Question 1
(1) The chameleon is famous for its ability to change color. (2) This ability is used primarily for communication and regulating body temperature. (3) It is less often used for camouflage.
What is the best way to combine these sentences to clarify the relationship between the ideas?
- The chameleon can change color, an ability famous for communication, regulating body temperature, and also for camouflage, which is used less often.
- Famous for its ability to change color for camouflage, the chameleon also uses this ability for communication and regulating its body temperature.
- The chameleon's famous ability to change color is used primarily for communication and regulating body temperature, not so much for camouflage.
- The chameleon is famous for its ability to change color, which is used less for camouflage and more for communication and regulating body temperature. (correct answer)
Explanation: When you encounter sentence combining questions, focus on preserving the logical relationships and emphasis from the original sentences while creating smooth, clear prose.
The original passage establishes a specific hierarchy: chameleons are famous for color-changing, this ability serves primarily two functions, and camouflage is actually the lesser use. The best combination should maintain this structure and contrast.
Choice D correctly preserves all these relationships. It keeps the chameleon's fame for color-changing as the main clause, then uses "which" to introduce the ability's actual uses. The phrase "less for camouflage and more for communication and regulating body temperature" clearly establishes the contrast between common assumptions (camouflage) and reality (communication/temperature regulation).
Choice A creates confusion by listing all three uses equally, losing the important distinction that camouflage is less common. The phrase structure also becomes awkward with "an ability famous for communication."
Choice B completely reverses the passage's meaning by putting camouflage first and making it seem primary, directly contradicting the original point that camouflage is the lesser function.
Choice C uses "not so much," which is less precise than the comparative structure in D. It also changes "regulating body temperature" to "regulating its body temperature," introducing an unnecessary pronoun.
For sentence combining questions on the SHSAT, always check that your chosen answer maintains the original meaning and emphasis. Pay special attention to contrast words like "primarily," "less often," or "more" — these signal important relationships that must be preserved in your combined sentence.
Question 2
(1) The concert was supposed to be outdoors. (2) A thunderstorm began an hour before the show. (3) The organizers moved the concert into the arena.
What is the best way to combine these sentences to show a clear cause-and-effect relationship?
- Although the concert was supposed to be outdoors, the organizers moved it into the arena after a thunderstorm began an hour before the show.
- Because a thunderstorm began an hour before the show, the organizers moved the concert, which was supposed to be outdoors, into the arena. (correct answer)
- When a thunderstorm began an hour before the outdoor concert, the organizers made the decision to move the event into the arena.
- The concert was supposed to be outdoors, and a thunderstorm began an hour before the show, so the organizers moved it into the arena.
Explanation: When you're asked to combine sentences to show cause-and-effect relationships, you need to identify which event caused another and choose the connecting word that makes this relationship clearest. Here, the thunderstorm (cause) led to moving the concert indoors (effect).
Choice B correctly establishes this cause-and-effect relationship by starting with "Because a thunderstorm began," which immediately signals that the storm is the cause. The subordinate clause "which was supposed to be outdoors" efficiently provides the background information without disrupting the main cause-and-effect flow. This structure follows the logical pattern: Because [cause], [effect].
Choice A uses "Although," which creates a contrast relationship rather than cause-and-effect. This suggests the concert was moved despite the storm, not because of it, which reverses the logical relationship.
Choice C uses "When," which shows timing but doesn't emphasize the causal connection as strongly as "because." While grammatically correct, it's less precise for highlighting cause-and-effect.
Choice D connects the ideas with "and" and "so," creating a choppy, coordinate structure. Though it shows the sequence of events, the cause-and-effect relationship isn't as clear or elegant as using a subordinating conjunction like "because."
For sentence combination questions on the SHSAT, always identify the logical relationship first (cause-and-effect, contrast, sequence, etc.), then choose the option with the most precise connecting words. "Because" is your strongest signal word for cause-and-effect relationships.
Question 3
(1) The old house stood on a hill overlooking the town. (2) It had been abandoned for decades. (3) Local children claimed it was haunted.
Which of the following is the best way to combine these sentences?
- The old house stood on a hill overlooking the town, where it had been abandoned for decades and was claimed by local children to be haunted.
- Local children claimed the old house on the hill overlooking the town was haunted, so it had been abandoned for many decades.
- Standing on a hill overlooking the town, the old house, which local children claimed was haunted, had been abandoned for decades. (correct answer)
- Abandoned for decades on a hill overlooking the town, the old house was the one that the local children all claimed was haunted.
Explanation: When you encounter sentence combining questions, focus on creating a clear, logical flow while preserving all the original information without changing the meaning or creating awkward constructions.
Choice C works best because it uses effective subordination and maintains logical relationships. The participial phrase "Standing on a hill overlooking the town" efficiently establishes the setting, while the relative clause "which local children claimed was haunted" smoothly incorporates the third piece of information. The main clause focuses on the house being abandoned, creating a natural emphasis and flow.
Choice A creates confusion with "where it had been abandoned" — the word "where" incorrectly suggests the abandonment happened in the town rather than describing the house itself. The phrasing also becomes unnecessarily wordy and awkward.
Choice B distorts the logical relationship by using "so," which incorrectly implies that the children's claims caused the abandonment. This changes the meaning of the original sentences, which simply present three separate facts about the house.
Choice D is wordy and awkward with phrases like "the one that the local children all claimed." The opening participial phrase "Abandoned for decades on a hill" also creates unclear modification — it suggests the house was abandoned specifically on the hill, rather than describing a house that happens to be on a hill.
For sentence combining questions, look for the choice that maintains the original meaning while creating the smoothest, most natural flow. Avoid options that change logical relationships between ideas or create unnecessarily complex or awkward phrasing.
Question 4
(1) The athlete trained rigorously for the competition. (2) She injured her ankle a week before the event. (3) She was unable to participate.
What is the best way to combine these sentences to clarify the relationship between the ideas?
- Although the athlete trained rigorously for the competition, she injured her ankle a week before the event and was consequently unable to participate. (correct answer)
- The athlete trained rigorously for the competition, but she injured her ankle a week before the event, so then she was unable to participate.
- After training rigorously for the competition, the athlete injured her ankle a week before the event, which meant she was unable to participate.
- The athlete's rigorous training for the competition was stopped when she injured her ankle a week before the event and could not participate.
Explanation: When combining sentences, you need to choose transitions that clearly show the logical relationships between ideas. This passage presents a sequence where effort leads to an unfortunate outcome that prevents success.
Choice A is correct because it uses the most precise transitions to clarify these relationships. "Although" effectively sets up the contrast between the athlete's preparation and the unfortunate outcome. "Consequently" explicitly shows that her inability to participate was a direct result of the injury. This creates a clear logical flow: despite preparation → injury occurred → result was inability to participate.
Choice B uses weaker transitions that don't clarify relationships as effectively. "But" and "so then" are more casual and less precise than "although" and "consequently." The phrase "so then" is also redundant and awkward.
Choice C changes the meaning by suggesting the training happened before everything else with "after training," when actually the training and injury timing overlap. "Which meant" is also less direct than "consequently" in showing cause and effect.
Choice D significantly alters the original meaning by focusing on the training being "stopped" rather than on the athlete's inability to participate in the competition. This shifts emphasis away from the main point about missing the event.
When combining sentences on the SHSAT, look for answer choices that use precise transitional words to show exact relationships (contrast, cause-effect, sequence) while preserving the original meaning. Avoid options that use vague transitions or change the focus of the passage.
Question 5
(1) The public library is expanding its collection of e-books. (2) This will provide more resources to patrons. (3) Patrons can access these resources from home.
What is the best way to combine these sentences?
- The public library is expanding its collection of e-books, and this will provide more resources to patrons, and they can access them from home.
- To provide more resources to patrons at home, the public library is expanding its collection of e-books which can be accessed there.
- Patrons can access more resources from home because the public library is expanding its collection of e-books for them.
- The public library is expanding its collection of e-books to provide more resources that patrons can access from the comfort of their home. (correct answer)
Explanation: When you encounter sentence combining questions, you're being tested on your ability to create clear, concise, and logically flowing sentences while preserving all the original meaning. The key is finding the version that connects ideas smoothly without redundancy or awkward phrasing.
The correct answer is D because it efficiently combines all three ideas in a logical sequence: the library's action (expanding e-books), the purpose (to provide more resources), and the benefit to patrons (home access). The phrase "to provide more resources that patrons can access from the comfort of their home" creates a clean cause-and-effect relationship using an infinitive phrase and a relative clause.
Choice A fails because it uses repetitive "and" connectors, creating an awkward, choppy rhythm. The pronoun "they" also creates ambiguity about whether it refers to patrons or resources.
Choice B contains unclear pronoun reference with "there" and "which." The phrase "patrons at home" suggests patrons are permanently at home, distorting the original meaning that patrons can access resources from home.
Choice C changes the emphasis by starting with patrons rather than the library's action, and "for them" is unnecessarily wordy since "patrons" was already mentioned.
For SHSAT sentence combining questions, look for the option that maintains the original meaning while using the most sophisticated and efficient sentence structure. Avoid choices with unclear pronoun references, awkward repetition, or unnecessarily complex phrasing. The best combinations flow naturally and show clear relationships between ideas.
Question 6
(1) The city of Pompeii was buried by a volcanic eruption in 79 A.D. (2) The eruption came from Mount Vesuvius. (3) The city was remarkably preserved under layers of ash.
What is the best way to combine these sentences?
- Buried by the eruption of Mount Vesuvius in 79 A.D., the city of Pompeii was remarkably preserved under layers of volcanic ash. (correct answer)
- The city of Pompeii was buried by a volcanic eruption from Mount Vesuvius in 79 A.D., therefore it was remarkably preserved under layers of ash.
- Mount Vesuvius erupted in 79 A.D., and it buried the city of Pompeii, which was then remarkably preserved under layers of ash.
- Remarkably preserved under layers of ash, the city of Pompeii was buried by the eruption of Mount Vesuvius in the year 79 A.D.
Explanation: When you encounter sentence combination questions, you need to create a single, flowing sentence that maintains all the original information while using effective writing techniques like subordination and proper sequencing.
The best combination uses a participial phrase to create a sophisticated sentence structure. Choice A begins with "Buried by the eruption of Mount Vesuvius in 79 A.D.," which serves as a participial phrase that efficiently combines the cause (the eruption) with the time (79 A.D.) and source (Mount Vesuvius). The main clause then focuses on the result: the remarkable preservation. This structure emphasizes the most interesting outcome—Pompeii's preservation—while subordinating the historical details.
Choice B uses "therefore," which creates a logical connection but results in a wordier, less elegant sentence. The word "therefore" also suggests a stronger causal relationship than what the original sentences imply.
Choice C strings together multiple clauses with "and" and "which," creating a choppy, run-on sentence that lacks the smooth flow of effective writing. This coordination-heavy approach doesn't prioritize information effectively.
Choice D places "Remarkably preserved under layers of ash" at the beginning, which creates confusion about the sequence of events. Readers might initially think Pompeii was already preserved before being buried, disrupting the logical flow of cause and effect.
For SHSAT sentence combination questions, look for answers that use participial phrases or subordinate clauses to create sophisticated sentence structures while maintaining chronological logic and emphasizing the most significant information in the main clause.
Question 7
(1) The author published her first novel. (2) The novel received critical acclaim. (3) Its sales were initially quite slow.
What is the best way to combine these sentences to highlight the contrast?
- Although the author's first novel received widespread critical acclaim after its publication, its sales were initially quite slow. (correct answer)
- The author published her first novel, which received critical acclaim, and its sales were initially quite slow.
- Receiving critical acclaim, the author's first novel had sales that were initially quite slow after she published it.
- The author's first novel received critical acclaim, but its sales were initially quite slow, so she published it.
Explanation: When combining sentences to show contrast, you need to use connecting words and structures that clearly highlight the opposing relationship between ideas. Here, the contrast is between critical success and poor sales performance.
Choice A effectively uses "although" to establish the contrast right from the start. This subordinating conjunction signals that despite one positive outcome (critical acclaim), there was an unexpected negative result (slow sales). The sentence flows logically and emphasizes the surprising nature of this contrast.
Choice B uses "and" as a connector, which simply adds information rather than showing contrast. While it mentions both facts, it doesn't highlight that these outcomes are surprising when considered together.
Choice C uses a participial phrase "Receiving critical acclaim" but fails to establish a clear contrast. The structure makes the sentence awkward and doesn't emphasize the unexpected relationship between critical praise and sales performance.
Choice D contains a logical error with "so she published it." This suggests the author published the novel because of the acclaim and slow sales, which doesn't make sense chronologically or causally. The novel was already published before it could receive reviews or sales data.
Remember that contrast words like "although," "despite," "however," and "while" are your best tools for highlighting opposing ideas. Look for the option that not only combines the information but also uses language that emphasizes the unexpected or contradictory relationship between the facts presented.
Question 8
(1) A new bridge is being constructed over the river. (2) It will connect the downtown area with the suburbs. (3) The project is expected to be completed next year.
What is the best way to combine these sentences?
- A new bridge being constructed over the river will connect the downtown area with the suburbs, and the project is expected to be completed next year.
- Connecting the downtown area with the suburbs, a new bridge is being constructed over the river, a project expected to be completed next year.
- A new bridge, which will connect the downtown area with the suburbs, is being constructed over the river and is expected to be completed next year. (correct answer)
- Expected to be completed next year, a new bridge is being constructed over the river; it will connect the downtown area with the suburbs.
Explanation: When you encounter sentence combination questions on the SHSAT, you're being tested on your ability to merge multiple ideas while maintaining clarity, proper grammar, and logical flow. The key is to preserve all essential information while creating a smooth, well-structured sentence.
Choice C effectively combines all three sentences by using a relative clause ("which will connect the downtown area with the suburbs") to embed the second sentence's information, then coordinates the two main actions with "and." This creates a clear, grammatically correct sentence that flows naturally: the bridge is being constructed AND is expected to be completed next year, with its purpose explained in the middle.
Choice A creates an awkward construction with "being constructed" that makes the sentence unclear about what's actually happening when. The participial phrase doesn't connect smoothly to the rest of the sentence.
Choice B uses a dangling modifier. "Connecting the downtown area with the suburbs" appears to modify "a new bridge," but the way it's positioned creates confusion about the sentence's main focus. The comma splice with "a project expected to be completed next year" also creates a grammatical error.
Choice D separates the ideas with a semicolon and places "Expected to be completed next year" at the beginning, which creates an awkward emphasis and doesn't flow as smoothly as the integrated approach in choice C.
Study tip: When combining sentences, look for the option that maintains all original information while using proper connecting words (relative pronouns, conjunctions) rather than awkward phrases or incorrect punctuation.
Question 9
(1) The invention of the printing press was a pivotal moment in history. (2) It was invented by Johannes Gutenberg around 1440. (3) It allowed for the mass production of books.
What is the best way to combine these sentences?
- Invented by Johannes Gutenberg around 1440, the printing press was a pivotal moment in history that allowed for the mass production of books.
- Allowing for the mass production of books, the printing press was invented by Johannes Gutenberg around 1440, which was a pivotal moment in history.
- Johannes Gutenberg invented the printing press around 1440, and it was a pivotal moment in history, allowing for the mass production of books.
- The invention of the printing press by Johannes Gutenberg around 1440 was a pivotal moment in history because it allowed for the mass production of books. (correct answer)
Explanation: When combining sentences, you need to maintain clear meaning while creating smooth, logical connections between ideas. This question tests your ability to merge related information without creating confusion or awkward constructions.
The correct answer is D because it preserves the logical flow and clarity of the original sentences. It starts with the main subject ("The invention of the printing press by Johannes Gutenberg around 1440"), identifies it as historically significant ("was a pivotal moment in history"), and then explains why using a clear causal connection ("because it allowed for the mass production of books"). The sentence structure is straightforward and easy to follow.
Answer A contains a structural problem: "the printing press was a pivotal moment in history" is illogical because the printing press itself wasn't a moment—the invention was the pivotal moment. Answer B creates confusion with its word order, making "which was a pivotal moment in history" seem to refer to the year 1440 rather than the invention itself. The opening phrase "Allowing for the mass production of books" also creates an awkward sentence start. Answer C uses coordination ("and") when subordination would be more effective, making the connection between ideas less clear and creating a somewhat choppy rhythm.
When combining sentences on the SHSAT, look for the version that maintains the clearest subject-verb relationships and uses appropriate connecting words to show how ideas relate. Avoid constructions that create ambiguous pronoun references or illogical connections between sentence elements.
Question 10
(1) The scientist conducted an experiment. (2) Her hypothesis was proven incorrect. (3) She learned valuable information from the results.
What is the best way to combine these sentences?
- The scientist conducted an experiment, and her hypothesis was proven incorrect, but she learned valuable information from the results.
- Having conducted an experiment where her hypothesis was proven incorrect, the scientist learned valuable information from the results anyway.
- Even though the scientist's hypothesis was proven incorrect in the experiment she conducted, she still learned valuable information from the results. (correct answer)
- The scientist learned valuable information from the results after her hypothesis was proven incorrect when she conducted her experiment.
Explanation: When you encounter sentence combining questions, you're being tested on your ability to merge ideas while maintaining clarity and showing the proper relationships between concepts. Look for the logical connections: cause and effect, contrast, sequence, or emphasis.
The correct answer is C because it effectively uses "Even though" to establish the contrast between the failed hypothesis and the positive outcome. This subordinating conjunction clearly shows that despite one negative result, something valuable still occurred. The sentence flows naturally and emphasizes the key message: scientific value can come from unexpected results.
Let's examine why the other options fall short. Choice A uses simple coordination with "and" and "but," which creates a choppy, list-like structure rather than showing sophisticated relationships between ideas. Choice B awkwardly includes "anyway" and uses a participial phrase that makes the sentence unnecessarily complex without adding clarity. Choice D creates confusion with its word order—"after her hypothesis was proven incorrect when she conducted her experiment" scrambles the chronology and makes the sentence harder to follow.
The key difference is that C uses subordination effectively. "Even though" creates a dependent clause that properly frames the contrast, while the independent clause delivers the main point about learning valuable information.
For sentence combining questions on the SHSAT, always look for the option that uses subordinating conjunctions (like "even though," "although," "because") to show clear relationships between ideas, rather than just stringing clauses together with "and" or "but."
Question 11
(1) Geysers are hot springs. (2) They intermittently eject a column of water and steam. (3) Old Faithful in Yellowstone National Park is a famous example.
Which of the following is the best way to combine these sentences?
- Old Faithful in Yellowstone National Park is a famous example of a geyser, which is a hot spring that ejects a column of water and steam.
- Geysers are hot springs, and they intermittently eject a column of water and steam, and Old Faithful is a famous example.
- Geysers, such as the famous Old Faithful in Yellowstone National Park, are hot springs that intermittently eject a column of water and steam. (correct answer)
- As hot springs that intermittently eject a column of water and steam, geysers are famously exemplified by Old Faithful in Yellowstone National Park.
Explanation: When combining sentences, you want to create a clear, smooth flow that maintains all the important information while avoiding awkward repetition or confusing structure.
Choice C works best because it presents the information in the most logical order: it starts with the general term "geysers," provides a specific example in parenthetical form ("such as the famous Old Faithful in Yellowstone National Park"), then defines what geysers are and do. This structure flows naturally from specific example to general definition, and the phrase "such as" elegantly incorporates the example without disrupting the main idea.
Choice A is problematic because it starts with the specific example (Old Faithful) before defining what a geyser is, creating a backwards flow of information. The relative clause structure also makes the sentence feel heavy and awkward.
Choice B uses repetitive coordination with multiple "and" connectors, creating a choppy, list-like feel rather than smooth integration. This approach doesn't truly combine the sentences—it just strings them together.
Choice D contains unnecessarily complex and awkward phrasing. The phrase "famously exemplified by" is wordy and formal to the point of being confusing. The opening phrase "As hot springs that..." also creates an unclear sentence structure.
When combining sentences on the SHSAT, look for the option that creates the smoothest flow from general to specific (or vice versa) while avoiding unnecessary wordiness or awkward constructions. The best combinations feel natural when read aloud.
Question 12
(1) The architect designed a new skyscraper. (2) The skyscraper has an innovative triangular shape. (3) It is also designed to be highly energy-efficient.
What is the best way to combine these sentences?
- The new skyscraper designed by the architect has an innovative triangular shape, and it is also designed to be highly energy-efficient.
- The architect designed a new skyscraper that, in addition to being highly energy-efficient, features an innovative triangular shape.
- The architect designed a new skyscraper with an innovative triangular shape that is also designed to be highly energy-efficient. (correct answer)
- Designed by the architect, the new skyscraper has an innovative triangular shape and is also designed to be highly energy-efficient.
Explanation: When combining sentences, you want to create a clear, concise structure that eliminates redundancy while preserving all important information. Look for opportunities to use subordinate clauses and phrases that show relationships between ideas.
Choice C works best because it efficiently combines all three sentences using a clean structure: "The architect designed a new skyscraper with an innovative triangular shape that is also designed to be highly energy-efficient." The prepositional phrase "with an innovative triangular shape" smoothly incorporates the second sentence, while the relative clause "that is also designed to be highly energy-efficient" adds the third piece of information. This creates one flowing sentence without awkward repetition.
Choice A unnecessarily repeats "designed" twice and uses a clunky coordinate structure with "and it is also designed," making the sentence wordy and repetitive. Choice B awkwardly places the energy efficiency information before the shape description using the phrase "in addition to," which disrupts the natural flow and makes the sentence harder to follow. Choice D starts with a participial phrase "Designed by the architect," which creates a less direct sentence structure, and still contains the redundant phrase "is also designed," making it unnecessarily wordy.
When combining sentences on the SHSAT, always look for the version that eliminates redundant words while maintaining clarity. The best combinations use subordinate structures (relative clauses, prepositional phrases) rather than just linking sentences with conjunctions. Practice identifying repeated words and phrases that can be streamlined without losing meaning.
Question 13
(1) The new software update was released. (2) It contains several security patches. (3) It also introduces a new user interface.
What is the best way to combine these sentences?
- The new software update was released, containing several security patches, and also introducing a new user interface.
- Released with several security patches, the new software update also introduces a completely new user interface.
- In addition to containing several security patches, the newly released software update introduces a new user interface. (correct answer)
- The new software update that was released contains several important security patches as well as introducing a new user interface.
Explanation: When you encounter sentence combination questions, you're being tested on your ability to create clear, concise, and grammatically correct compound sentences while maintaining the original meaning and improving flow.
Choice C is correct because it creates the most polished and coherent sentence. The phrase "In addition to containing several security patches" effectively establishes one feature while smoothly transitioning to introduce the second feature with "introduces a new user interface." The structure is parallel, clear, and eliminates unnecessary words while preserving all the original information.
Let's examine why the other options fall short. Choice A creates an awkward construction with "containing...and also introducing" — the mixed verb forms (containing vs. introducing) create an unparallel structure that sounds clunky. Choice B changes the meaning by adding "completely" before "new user interface," which wasn't in the original text, and the phrase "Released with" creates an unclear relationship between the release and the patches. Choice D suffers from a major grammatical error with "contains...as well as introducing" — this mixes a finite verb (contains) with a gerund (introducing), creating faulty parallelism.
When tackling sentence combination questions, always check for three key elements: grammatical correctness, parallel structure, and preservation of original meaning. Watch out for answers that add new information not present in the original sentences or create awkward mixed constructions. The best combined sentence will flow naturally while maintaining precise meaning.
Question 14
(1) The Roman Empire was vast. (2) It stretched from Britain to the Middle East. (3) Its network of roads connected its distant provinces.
What is the best way to combine these sentences?
- The Roman Empire was vast, stretching from Britain to the Middle East, and its network of roads connected its distant provinces.
- The vast Roman Empire stretched from Britain to the Middle East, with its network of roads connecting its distant provinces. (correct answer)
- Stretching from Britain to the Middle East, the vast Roman Empire's network of roads connected its distant provinces.
- The Roman Empire was vast, stretching from Britain to the Middle East, its network of roads connecting its distant provinces.
Explanation: When you encounter sentence combining questions, you're being tested on your ability to create smooth, clear, and grammatically correct compound or complex sentences. The goal is to maintain all the original meaning while eliminating choppiness and redundancy.
Choice B works best because it creates a flowing, well-structured sentence using effective subordination. "The vast Roman Empire stretched from Britain to the Middle East" serves as the main clause, while "with its network of roads connecting its distant provinces" functions as a prepositional phrase that smoothly adds supporting information. This structure is both grammatically sound and easy to follow.
Choice A is grammatically correct but awkward because it uses two different connecting methods—first a participial phrase ("stretching") then a coordinating conjunction ("and")—creating an uneven rhythm. Choice C changes the emphasis incorrectly by making the roads the main focus rather than the empire's vastness and geographic reach, which distorts the original meaning. Choice D commits a serious grammatical error by creating a comma splice—the phrase "its network of roads connecting its distant provinces" cannot stand alone as an independent clause, so it cannot be joined to the previous independent clause with just a comma.
For sentence combining questions, look for the choice that maintains parallel structure, uses appropriate conjunctions or transitional phrases, and preserves the logical emphasis of the original sentences. Avoid comma splices and awkward shifts in grammatical structure.
Question 15
(1) The chef prepared the meal with great care. (2) The ingredients were all locally sourced. (3) The diners were very impressed.
What is the best way to combine these sentences to show a cause-and-effect relationship?
- Because the chef prepared the meal with great care using locally sourced ingredients, the diners were very impressed. (correct answer)
- The chef prepared the meal with great care using locally sourced ingredients, which greatly impressed the diners.
- The diners were very impressed with the meal, and the chef had prepared it with great care, and the ingredients were locally sourced.
- Preparing the meal with great care and using locally sourced ingredients, the chef's work was very impressive to the diners.
Explanation: When you encounter questions about combining sentences to show cause-and-effect relationships, look for transition words and sentence structures that clearly establish what caused what. The key is identifying which events are causes and which are effects, then choosing the option that makes this relationship most explicit.
In this passage, the chef's careful preparation and use of local ingredients are the causes, while the diners' impression is the effect. Answer A effectively combines all three sentences using "Because" at the beginning, which immediately signals a cause-and-effect structure. The word "because" explicitly shows that the chef's actions (careful preparation + local sourcing) directly led to the result (impressed diners).
Answer B uses "which" to connect the ideas, but this creates more of a descriptive relationship than a clear cause-and-effect one. The structure suggests the information is additional rather than causal.
Answer C simply strings the sentences together with "and," creating no cause-and-effect relationship at all. The conjunction "and" just adds information without showing how the pieces connect logically.
Answer D has a structural problem with the participial phrase. "Preparing the meal" and "using ingredients" seem to modify "the chef's work" rather than "the chef," creating awkward and unclear meaning. Additionally, it doesn't establish as strong a causal connection.
Remember: When combining sentences to show cause and effect, look for subordinating conjunctions like "because," "since," or "as" that explicitly signal causal relationships. These words immediately tell your reader which part is the cause and which is the effect.
Question 16
(1) The museum acquired a new painting. (2) The painting is from the 17th century. (3) Its artist is unknown.
What is the best way to combine these sentences?
- The museum acquired a new 17th-century painting by an unknown artist. (correct answer)
- The museum acquired a new painting from the 17th century by an artist who is unfortunately unknown.
- A new painting acquired by the museum is from the 17th century, and its artist is unknown.
- Its artist unknown, the museum acquired a new painting from the 17th century.
Explanation: When you encounter sentence combining questions, you're being tested on your ability to create clear, concise writing that eliminates unnecessary words while preserving all important information. The goal is to find the most efficient way to express the same ideas.
Choice A is correct because it transforms the three separate sentences into one streamlined sentence by converting the information into modifying phrases. "17th-century" becomes a compound adjective, and "by an unknown artist" becomes a prepositional phrase. This creates the most concise version while maintaining all the essential information: the museum's acquisition, the painting's age, and the artist's anonymity.
Choice B is wordy and awkward. The phrase "who is unfortunately unknown" is unnecessarily long, and "unfortunately" adds an opinion not present in the original sentences. The word "from" is also redundant when you can use the compound adjective "17th-century."
Choice C fails to truly combine the sentences effectively. It keeps the same choppy structure with "and" connecting two independent ideas, making it feel like two sentences forced together rather than one fluid sentence.
Choice D creates an awkward construction with "Its artist unknown" at the beginning. This absolute construction is grammatically complex and sounds unnatural, making the sentence harder to read than necessary.
Strategy tip: In sentence combining questions, look for the version that eliminates redundant words and creates the smoothest flow. The best answer usually converts full clauses into modifying phrases or adjectives, making the writing more sophisticated and concise.
Question 17
(1) The Amazon rainforest produces a significant amount of the world's oxygen. (2) It is home to millions of species of plants and animals. (3) It is facing threats from deforestation.
What is the best way to combine these sentences?
- The Amazon rainforest produces a significant amount of the world's oxygen and is home to millions of species, but it is facing threats from deforestation.
- Despite producing much of the world's oxygen and being home to millions of species, the Amazon rainforest is facing severe threats from deforestation. (correct answer)
- The Amazon rainforest produces a lot of oxygen and has millions of species, so it is facing threats from deforestation.
- Producing the world's oxygen and being home to millions of species, the Amazon rainforest is facing threats from deforestation.
Explanation: When combining sentences, you need to consider both the grammatical structure and the logical relationships between ideas. This question tests your ability to create a cohesive sentence that preserves the original meaning while showing how the ideas connect.
The correct answer is B because it uses "Despite" to create a meaningful contrast between the Amazon's positive qualities (producing oxygen and housing species) and the negative threat it faces (deforestation). This contrast structure makes logical sense—it's particularly concerning that such an important ecosystem is under threat. The word "severe" also appropriately emphasizes the seriousness of deforestation without changing the core meaning.
Answer A uses "but" to show contrast, which is grammatically correct, but the sentence structure is less sophisticated and doesn't emphasize the irony of the situation as effectively as "Despite."
Answer C incorrectly uses "so," which suggests that producing oxygen and housing species somehow causes deforestation threats. This creates a illogical cause-and-effect relationship that contradicts the intended meaning.
Answer D uses a participial phrase structure that's grammatically acceptable but fails to show any logical relationship between the ideas. It simply lists the facts without indicating whether they're connected by contrast, cause-and-effect, or another relationship.
Strategy tip: When combining sentences, identify the logical relationship first (contrast, cause-and-effect, addition, etc.), then choose connecting words that accurately express that relationship. Words like "despite," "although," "because," and "so" each signal different logical connections.
Question 18
(1) The author researched her topic for over a year. (2) She traveled to three different continents. (3) She wanted her book to be as accurate as possible.
What is the best way to combine these sentences to clarify the author's motivation?
- The author researched her topic for over a year, and she traveled to three different continents, and she wanted her book to be accurate.
- After researching her topic for over a year and traveling to three different continents, the author wanted her book to be as accurate as possible.
- The author researched her topic for over a year and traveled to three different continents, although she wanted her book to be as accurate as possible.
- To ensure her book would be as accurate as possible, the author spent over a year researching her topic and traveling to three different continents. (correct answer)
Explanation: When you encounter a sentence combination question, look for the logical relationship between the ideas. Here, you need to identify that the author's desire for accuracy is her motivation for doing research and traveling—it's the reason behind her actions, not just another thing she did.
Choice D correctly establishes this cause-and-effect relationship by starting with "To ensure her book would be as accurate as possible." This structure immediately shows that accuracy was the driving purpose behind everything else the author did. The phrase "to ensure" creates a clear causal connection, making the research and travel the means to achieve the goal of accuracy.
Choice A fails because it simply lists three actions with "and" connectors, treating the desire for accuracy as just another event rather than the motivation behind the others. Choice B uses "after" to show time sequence, but this suggests the author only wanted accuracy as an afterthought following her research, which doesn't capture the motivational relationship. Choice C employs "although," which creates contrast and suggests the author wanted accuracy despite her research efforts—the opposite of the intended meaning.
The key difference is that D uses purpose language ("to ensure") while the other choices use additive (A), temporal (B), or contrasting (C) connections that miss the motivational relationship entirely.
Strategy tip: When combining sentences about someone's actions, always look for the underlying "why"—the motivation or purpose. Words like "to," "in order to," and "so that" often signal the correct relationship better than simple connectors like "and" or "after."
Question 19
(1) The desert is a harsh environment. (2) Many plants and animals have adapted to survive there. (3) The cactus, for example, stores water in its stem.
Which of the following best combines these sentences?
- The desert is a harsh environment, so many plants and animals, like the cactus that stores water in its stem, have adapted to survive there.
- The cactus stores water in its stem, for example, because many plants and animals have adapted to survive in the desert, which is a harsh environment.
- Although the desert is a harsh environment, many plants and animals have adapted to survive there, such as the cactus, which stores water in its stem.
- Many plants and animals have adapted to survive in the harsh environment of the desert; the cactus, for instance, stores water in its stem. (correct answer)
Explanation: When you encounter sentence combining questions, you're being tested on your ability to merge ideas while maintaining clear relationships between them and preserving all original information.
Choice D is correct because it effectively combines all three sentences while maintaining logical flow and clarity. It starts with the main idea that "many plants and animals have adapted," explains where they've adapted ("in the harsh environment of the desert"), and then provides a specific example using a semicolon and transitional phrase ("for instance") to introduce the cactus detail. This structure creates a smooth progression from general concept to specific example.
Choice A is problematic because it creates an awkward, run-on construction with "like the cactus that stores water in its stem" embedded within the main clause, making it difficult to follow.
Choice B scrambles the logical order by starting with the specific example (cactus) before establishing the general principle about adaptation. The phrase "for example" appears in the wrong position, disrupting the natural flow from general to specific.
Choice C uses "Although" to suggest contrast between the desert being harsh and animals adapting, but this relationship is actually cause-and-effect, not contrasting. Animals adapt because the environment is harsh, not despite it being harsh.
For sentence combining questions, look for the choice that maintains logical relationships between ideas, preserves all original information, and uses appropriate transitional words. Pay special attention to whether conjunctions like "although," "because," and "so" accurately reflect the relationships between the ideas you're combining.
Question 20
(1) The island is remote and difficult to reach. (2) It has a unique ecosystem. (3) Many of its species are found nowhere else on Earth.
What is the best way to combine these sentences?
- Because the island is remote and difficult to reach, it has developed a unique ecosystem in which many species are found nowhere else on Earth. (correct answer)
- The island is remote and difficult to reach, so it has a unique ecosystem with many species found nowhere else on Earth.
- The island is remote and difficult to reach, but it has a unique ecosystem where many of its species are found nowhere else on Earth.
- The unique ecosystem of the remote and hard-to-reach island has many species that cannot be found anywhere else on Earth.
Explanation: When combining sentences, you need to identify the logical relationship between the ideas and choose the connector that best expresses that relationship. These three sentences present a cause-and-effect chain: the island's isolation leads to its unique ecosystem, which results in endemic species.
Choice A correctly uses "because" to show that the island's remoteness caused its unique ecosystem to develop. The phrase "in which" smoothly connects the ecosystem to the endemic species, creating a clear causal chain. This combination preserves all the original meaning while showing how geographic isolation drives evolutionary uniqueness.
Choice B uses "so," which suggests the unique ecosystem is simply a result of being remote, but it doesn't capture the developmental process that isolation creates. The connection feels too simple for this complex relationship.
Choice C uses "but," which indicates contrast or contradiction. However, there's no opposing relationship here—the remoteness and unique ecosystem actually support each other rather than conflict.
Choice D combines the information but eliminates the crucial cause-and-effect relationship entirely. While it mentions the island is "remote and hard-to-reach," it doesn't explain why this geographic isolation matters for the ecosystem's development.
When combining sentences on the SHSAT, always identify the logical relationship first—cause and effect, contrast, addition, or sequence. Then choose the connector word that most precisely expresses that relationship. Watch for answer choices that preserve important causal connections rather than just listing facts.
