Question 1

1. The tree was tall, but it had wide branches and shaded our picnic table.
2. The tall tree with wide branches shaded our picnic table. (correct answer)
3. The tree was tall, it had wide branches, it shaded our picnic table.
4. The tree was tall. It had wide branches. It shaded our picnic table.

Explanation: This question tests CCSS.L.5.3.a: expanding, combining, and reducing sentences for meaning, reader/listener interest, and style. Effective writers vary their sentences by combining related ideas using coordinating conjunctions (and, but, so) or subordinating conjunctions (because, when, while), creating compound or complex sentences that improve flow and maintain reader interest. The stimulus presents three choppy sentences describing different aspects of the same tree, creating an opportunity to combine descriptive elements into one concise sentence. Choice B is correct because it transforms the separate descriptive sentences into one fluid sentence by using 'tall' as an adjective modifier and 'with wide branches' as a prepositional phrase modifier, eliminating all repetition of 'tree' and 'it' while maintaining all original information in a more sophisticated structure. Choice C represents a comma splice error, joining three independent clauses with only commas and no conjunctions, which creates a run-on sentence that violates grammar rules. To help students: Model how to transform separate descriptive sentences into single sentences using adjectives and prepositional phrases. Have students practice identifying the main noun and converting related sentences into modifying phrases. Use visual diagrams to show how descriptive elements can branch off from a main noun. Watch for: comma splices when students try to join multiple descriptions, and loss of information when students oversimplify combinations.

Question 2

1. Marcus finished his poster, added color, and wrote a title at the top. (correct answer)
2. Marcus finished his poster, and he wrote a title, but he added color.
3. Marcus finished his poster and Marcus added color, and Marcus wrote a title at the top.
4. Marcus finished his poster. Marcus added color. Marcus wrote a title at the top.

Explanation: This question tests CCSS.L.5.3.a: expanding, combining, and reducing sentences for meaning, reader/listener interest, and style. Effective writers vary their sentences by combining related ideas using coordinating conjunctions (and, but, so) or subordinating conjunctions (because, when, while), creating compound or complex sentences that improve flow and maintain reader interest. The stimulus presents three choppy sentences with repeated subject 'Marcus' describing sequential actions in completing a poster, creating an opportunity to combine using a compound predicate. Choice C is correct because it uses a compound predicate structure (finished, added, and wrote) that eliminates the repetitive subject while maintaining the logical sequence of poster creation, creating a smooth, parallel construction. Choice D represents an illogical use of 'but' which suggests contrast between writing a title and adding color, when these are complementary actions in poster creation, demonstrating a common error of misusing conjunctions. To help students: Model how to identify sequential versus contrasting actions before choosing conjunctions. Have students act out or visualize the actions to determine their relationship (sequential, simultaneous, or contrasting). Use graphic organizers to map action sequences before writing. Watch for: students using 'but' randomly without considering meaning, forgetting commas in series, or changing the logical sequence of events when combining.

Question 3

1. The class planted seeds, and the class watered them every day.
2. The class planted seeds and watered them every day to help them grow. (correct answer)
3. The class planted seeds watered them every day to help them grow.
4. The class planted seeds, but watered them every day to help them grow.

Explanation: This question tests CCSS.L.5.3.a: expanding, combining, and reducing sentences for meaning, reader/listener interest, and style. Effective writers vary their sentences by combining related ideas using coordinating conjunctions (and, but, so) or subordinating conjunctions (because, when, while), creating compound or complex sentences that improve flow and maintain reader interest. The stimulus presents two sentences about planting and watering seeds with an implied purpose, creating an opportunity to combine while adding the purpose relationship. Choice B is correct because it combines the two actions with 'and' while adding an infinitive phrase 'to help them grow' that clarifies the purpose of watering, creating a sentence that flows smoothly while enhancing meaning through the addition of purpose. Choice C represents a missing conjunction error by joining 'seeds' and 'watered' without any connecting word or punctuation, creating a run-on sentence that is grammatically incorrect and confusing. To help students: Model how infinitive phrases (to + verb) can show purpose or intention. Have students identify the 'why' behind actions before combining sentences to see if purpose can be added. Use mentor texts to show how authors clarify intentions through purposeful combining. Watch for: students creating run-ons by omitting conjunctions, using 'but' when showing addition or purpose, or losing important relationship information when combining.

Question 4

1. Amir packed his lunch and Amir grabbed his backpack and Amir ran.
2. Amir packed his lunch, grabbed his backpack, and ran to the bus stop. (correct answer)
3. While Amir packed his lunch, his backpack ran to the bus stop.
4. Amir packed his lunch. Amir grabbed his backpack. Amir ran to the bus stop.

Explanation: This question tests CCSS.L.5.3.a: expanding, combining, and reducing sentences for meaning, reader/listener interest, and style. Effective writers vary their sentences by combining related ideas using coordinating conjunctions (and, but, so) or subordinating conjunctions (because, when, while), creating compound or complex sentences that improve flow and maintain reader interest. The stimulus presents three choppy sentences with repeated subject 'Amir' describing a sequence of actions, creating an opportunity to combine them into a series with compound predicates. Choice B is correct because it creates a compound predicate with three verbs in a series (packed, grabbed, and ran), using commas and 'and' appropriately while eliminating the repetitive 'Amir,' which creates a smooth, flowing sentence that maintains the chronological sequence. Choice C represents poor combination technique by keeping unnecessary repetitions of 'Amir' and 'and,' creating an awkward, run-on structure that doesn't improve the original choppy writing. To help students: Model how to create series with three or more verbs, emphasizing comma placement before the final 'and' in a series. Have students identify action sequences in their writing and practice combining them using compound predicates. Use physical demonstrations where students act out sequences to understand how multiple actions by one subject can be combined. Watch for: students who forget commas in a series, those who use too many 'ands,' and confusion about when to keep or remove repeated subjects.

Question 5

1. While Emma opened the window, and felt the cool air, she smiled.
2. Emma opened the window, felt the cool air, and smiled. (correct answer)
3. Emma opened the window, she felt the cool air, and she smiled.
4. Emma opened the window. Emma felt the cool air. Emma smiled.

Explanation: This question tests CCSS.L.5.3.a: expanding, combining, and reducing sentences for meaning, reader/listener interest, and style. Effective writers vary their sentences by combining related ideas using coordinating conjunctions (and, but, so) or subordinating conjunctions (because, when, while), creating compound or complex sentences that improve flow and maintain reader interest. The stimulus presents three short sentences with repeated subject 'Emma' describing a sequence of actions and reactions, creating an opportunity to combine using a compound predicate. Choice C is correct because it uses a compound predicate (opened, felt, and smiled) that eliminates repetitive subjects while maintaining the cause-and-effect sequence of opening leading to feeling leading to smiling, creating a flowing sentence with parallel verb forms. Choice D represents incorrect punctuation and conjunction use by combining 'while' with 'and' inappropriately, creating a grammatically incorrect construction that confuses the time relationship between the actions. To help students: Model how compound predicates maintain chronological or causal sequences. Have students identify whether actions happen sequentially or simultaneously before combining. Practice combining sentences orally first to hear natural flow before writing. Watch for: students overusing conjunctions creating awkward constructions, losing the logical sequence of cause and effect, or creating fragments by omitting necessary subjects.

Question 6

1. Maya packed her lunch and she ran to the bus stop.
2. Maya packed her lunch, grabbed her backpack, and ran to the bus stop. (correct answer)
3. Although Maya packed her lunch, she grabbed her backpack and ran to the bus stop.
4. Maya packed her lunch, she grabbed her backpack, and she ran to the bus.

Explanation: This question tests CCSS.L.5.3.a: expanding, combining, and reducing sentences for meaning, reader/listener interest, and style. Effective writers vary their sentences by combining related ideas using coordinating conjunctions (and, but, so) or subordinating conjunctions (because, when, while), creating compound or complex sentences that improve flow and maintain reader interest. The stimulus presents three choppy sentences with repeated subject 'Maya' that describe sequential actions, creating an opportunity to combine using a compound predicate structure. Choice B is correct because it uses a compound predicate (packed, grabbed, and ran) which eliminates repetitive subjects while maintaining the sequential meaning and improving flow through parallel structure. Choice A represents unnecessary repetition by keeping 'she' before each verb, which creates wordiness without improving clarity. To help students: Model how compound predicates work when one subject performs multiple actions in sequence. Have students identify repetitive subject-verb patterns in their own writing and practice combining them into compound predicates while maintaining parallel verb forms. Use mentor texts to show how authors create rhythm through varied sentence structures. Watch for: students who forget to maintain parallel verb forms or who create comma splices when combining sentences.

Question 7

1. It started raining, but Chen and his sister went inside to play a board game.
2. Because it started raining, Chen and his sister played a board game outside.
3. It started raining, Chen and his sister went inside to play a board game.
4. Because it started raining, Chen and his sister went inside to play a board game. (correct answer)

Explanation: This question tests CCSS.L.5.3.a: expanding, combining, and reducing sentences for meaning, reader/listener interest, and style. Effective writers vary their sentences by combining related ideas using coordinating conjunctions (and, but, so) or subordinating conjunctions (because, when, while), creating compound or complex sentences that improve flow and maintain reader interest. The stimulus presents two sentences showing a cause-and-effect relationship between rain starting and the children going inside, creating an opportunity to combine with a subordinating conjunction that shows causation. Choice A is correct because it uses 'because' to establish the causal relationship between the rain (cause) and going inside (effect), creating a complex sentence that clearly shows why the action happened while maintaining the original meaning. Choice C represents an incorrect conjunction choice because 'but' suggests contrast or opposition, implying the children went inside despite the rain rather than because of it, which changes the logical relationship between the ideas. To help students: Explicitly teach cause-and-effect relationships and appropriate conjunctions (because, since, as a result). Have students identify whether sentences show time, cause, contrast, or addition relationships before selecting conjunctions. Use graphic organizers to map cause-and-effect relationships in their own writing. Watch for: students using 'but' when they mean 'so' or 'because,' creating comma splices, or changing the logical relationship between ideas.

Question 8

1. After Yuki finished, her backpack checked her answers and put it in homework.
2. After Yuki finished her homework, she checked her answers and put it in her backpack. (correct answer)
3. Yuki finished her homework. Yuki checked her answers. Yuki put it in her backpack.
4. Yuki finished her homework, and she checked her answers, and she put it in her backpack.

Explanation: This question tests CCSS.L.5.3.a: expanding, combining, and reducing sentences for meaning, reader/listener interest, and style. Effective writers vary their sentences by combining related ideas using subordinating conjunctions that show time relationships, creating complex sentences that improve flow and eliminate repetitive subjects. The stimulus presents three choppy sentences with repeated subject 'Yuki' describing a sequence of actions, creating an opportunity to combine with time subordination. Choice C is correct because it uses 'After' to establish the time relationship, then combines the remaining actions with 'and' in a compound predicate, eliminating all repetition of 'Yuki' while maintaining the chronological sequence. Choice D represents a nonsense error which scrambles the words to create an illogical sentence where 'her backpack checked her answers,' showing complete misunderstanding of sentence structure. This error is common when students focus on rearranging words without maintaining logical subject-verb relationships. To help students: Model using time subordinators (after, before, when, while) to show sequence. Have students identify chronological actions in their writing and practice combining them while checking that subjects and verbs still make logical sense.

Question 9

1. Sofia finished her math work, but she checked her answers and turned it in.
2. Sofia finished her math work and turned it in, but she never checked it.
3. Sofia finished her math work, she checked her answers, and she turned it in.
4. Sofia finished her math work, checked her answers, and turned it in. (correct answer)

Explanation: This question tests CCSS.L.5.3.a: expanding, combining, and reducing sentences for meaning, reader/listener interest, and style. Effective writers vary their sentences by combining related ideas using coordinating conjunctions (and, but, so) or subordinating conjunctions (because, when, while), creating compound or complex sentences that improve flow and maintain reader interest. The stimulus presents three sequential actions with the same subject 'Sofia', creating an opportunity to combine using a compound predicate. Choice B is correct because it creates a compound predicate (finished, checked, and turned in) with one subject, eliminating repetition while maintaining the logical sequence of actions. Choice A represents ineffective combination keeping unnecessary subject repetition 'she', while C incorrectly uses 'but' suggesting contrast where none exists. To help students: Model compound predicates where one subject performs multiple actions. Have students highlight repeated subjects and practice combining the verbs. Use graphic organizers showing subject + verb1 + verb2 + verb3 structure. Watch for: students keeping pronouns when creating compound predicates, and incorrect conjunction use that changes relationships between actions.

Question 10

1. The desert is hot. The desert is dry. The desert has little rain.
2. The desert is hot and the desert is dry, and it has little rain.
3. The desert is hot, dry, and has little rain. (correct answer)
4. The desert is hot, and it has many lakes because it rains a lot.

Explanation: This question tests CCSS.L.5.3.a: expanding, combining, and reducing sentences for meaning, reader/listener interest, and style. Effective writers vary their sentences by combining related ideas using coordinating conjunctions (and, but, so) or subordinating conjunctions (because, when, while), creating compound or complex sentences that improve flow and maintain reader interest. The stimulus presents three choppy sentences with repeated subject 'The desert' describing related characteristics, creating an opportunity to combine using a series with parallel structure. Choice C is correct because it combines all three characteristics into one concise sentence using commas in a series, eliminating repetition while maintaining all information about the desert being hot, dry, and having little rain. Choice B represents ineffective combination that keeps unnecessary repetition of 'the desert' and creates awkward coordination, while D changes the meaning entirely by stating the opposite (many lakes, lots of rain). To help students: Model how to identify related characteristics that can be combined in a series. Practice creating parallel structure when listing multiple attributes. Show how commas in a series create cleaner sentences than multiple 'and' conjunctions. Watch for: students creating run-on sentences by overusing 'and', and meaning changes when students don't carefully read what they're combining.

Question 11

1. Although it started raining, we went inside the library.
2. It started raining, we went inside the library.
3. It started raining, and we stayed outside the library.
4. When it started raining, we went inside the library. (correct answer)

Explanation: Going inside happened because of the rain, so joining the ideas with "When" shows that time and cause clearly: "When it started raining, we went inside the library." Choice D is correct. Choice A uses "Although," which wrongly suggests a contrast, Choice B is a comma splice, and Choice C changes the meaning to "stayed outside," so none combines the sentences well.

Question 12

1. The desert is dry, it gets little rain, many plants store water.
2. Although the desert is dry, it gets little rain because many plants store water.
3. The desert is dry, and it gets little rain, but plants do not need water.
4. The desert is dry; it gets little rain, so many plants store water. (correct answer)

Explanation: This question tests CCSS.L.5.3.a: expanding, combining, and reducing sentences for meaning, reader/listener interest, and style. Effective writers vary their sentences by combining related ideas using appropriate punctuation and conjunctions that show logical relationships between ideas, creating compound or complex sentences that improve flow and maintain reader interest. The stimulus presents three related facts about deserts that show a cause-and-effect chain: dryness leads to little rain, which causes plants to adapt by storing water. Choice A is correct because it uses a semicolon to connect the first closely related statement, then uses 'so' to show the cause-and-effect relationship between little rain and plants storing water, maintaining all original meanings while creating variety. Choice B represents a comma splice error which incorrectly joins three complete sentences with only commas, creating a run-on that violates punctuation rules. This error is common when students know they should combine sentences but haven't learned that commas alone cannot join complete thoughts. To help students: Explicitly teach semicolon use for closely related complete sentences and 'so' for showing results. Have students identify cause-and-effect relationships in informational writing and practice using appropriate conjunctions (because, so, therefore) to show these connections clearly.

Question 13

1. The library was quiet. The library was warm. The library was bright.
2. The library was quiet, warm, and bright. (correct answer)
3. The library was quiet and the library was warm and the library was bright.
4. The library was quiet, the library was warm, the library was bright.

Explanation: This question tests CCSS.L.5.3.a: expanding, combining, and reducing sentences for meaning, reader/listener interest, and style. Effective writers vary their sentences by combining related ideas using coordinating conjunctions (and, but, so) or subordinating conjunctions (because, when, while), creating compound or complex sentences that improve flow and maintain reader interest. The stimulus presents three repetitive sentences with the same subject and verb structure describing different qualities of the library, creating an opportunity to combine using a series with commas and a coordinating conjunction. Choice B is correct because it combines the three adjectives (quiet, warm, and bright) into a properly punctuated series, eliminating repetition while maintaining all descriptive information in a concise, flowing sentence. Choice C represents excessive repetition by keeping 'the library was' before each adjective connected with 'and,' which creates wordiness and choppy rhythm without adding clarity or meaning. To help students: Model how to identify sentences with the same subject-verb pattern that can be combined into a series. Have students practice creating lists with proper comma usage and the final 'and' before the last item. Use mentor texts to show how authors use series to create rhythm and avoid repetition. Watch for: students forgetting commas in a series, creating run-on sentences by connecting too many ideas, or changing meaning by combining unrelated ideas.

Question 14

1. First Amir fed the fish, then he cleaned the tank, after that he washed his hands.
2. After Amir fed the fish, he cleaned the tank and then washed his hands. (correct answer)
3. After Amir fed the fish, he cleaned the tank, he washed his hands.
4. After Amir fed the fish, he cleaned the tank, then washing his hands.

Explanation: Choice B combines the ideas smoothly and keeps the order clear: "After Amir fed the fish, he cleaned the tank and then washed his hands." So it is correct. Choice A is wordy and choppy, Choice C is a run-on (comma splice), and Choice D switches to "washing" and breaks the verb pattern, so none is the best combination.

Question 15

1. The puppy ran across the yard, the puppy chased a leaf, and barked loudly.
2. The puppy ran across the yard and the puppy chased a leaf and the puppy barked loudly.
3. The puppy ran across the yard. The puppy chased a leaf. The puppy barked loudly.
4. The puppy ran across the yard, chased a leaf, and barked loudly. (correct answer)

Explanation: Choice D combines the three ideas into one smooth sentence with a matching list of actions: "ran across the yard, chased a leaf, and barked loudly." So it is correct. Choice A is a run-on (comma splice), Choice B repeats "the puppy" too many times, and Choice C leaves the choppy separate sentences, so none improves the style.

Question 16

1. The tall tree was shady and near the playground. (correct answer)
2. The tree was tall, the tree was shady, and the tree was near the playground.
3. The tree was tall and it was shady, near the playground.
4. Although the tree was tall, it was shady and near the playground.

Explanation: The most effective revision moves "tall" in front of "tree" and joins the other details smoothly: "The tall tree was shady and near the playground." Choice A does this, so it is correct. Choice B just repeats "the tree was" three times, Choice C is choppy, and Choice D adds "Although," which wrongly suggests a contrast, so none combines the ideas as well.

Question 17

1. Yuki opened the box. She saw a note. She smiled.
2. Yuki opened the box, saw a note, and smiled. (correct answer)
3. Yuki opened the box she saw a note and smiled.
4. Although Yuki opened the box, she saw a note and smiled.

Explanation: This question tests CCSS.L.5.3.a: expanding, combining, and reducing sentences for meaning, reader/listener interest, and style. Effective writers vary their sentences by combining related ideas using coordinating conjunctions (and, but, so) or subordinating conjunctions (because, when, while), creating compound or complex sentences that improve flow and maintain reader interest. The stimulus presents three very short, choppy sentences describing a quick sequence of actions by the same subject, creating an opportunity to combine them into one flowing sentence with compound predicates. Choice B is correct because it creates a series of three verbs (opened, saw, and smiled) as compound predicates, using commas appropriately and eliminating the repetitive 'She,' which transforms the choppy writing into a smooth, engaging sentence that maintains the rapid sequence of events. Choice C represents a run-on sentence error by joining clauses without proper punctuation between 'box' and 'she,' creating confusion about where one thought ends and another begins. To help students: Model how very short sentences can often be combined into compound predicates when they share the same subject and show related actions. Have students identify 'choppy' passages in their writing and experiment with different combination strategies. Practice reading sentences aloud to hear how combining improves flow and pacing. Watch for: missing punctuation when combining, especially in series, and students who combine sentences that should remain separate for dramatic effect.

Question 18

1. When it started raining, Jamal went inside and forgot his sister outside. (correct answer)
2. It started raining, but Jamal and his sister went inside the house.
3. When it started raining, Jamal and his sister went inside the house.
4. It started raining, Jamal and his sister went inside the house.

Explanation: The original sentences say only Jamal went inside and he forgot his sister, so the best combination keeps that exact meaning. Choice A does this and joins the ideas smoothly, so it is correct. Choices B and C change the meaning by having the sister go inside too, and Choice D also changes the meaning and is a comma splice, so none is right.

Question 19

1. When the bell rang, Jamal closed his book and lined up for recess. (correct answer)
2. When the bell rang, Jamal lined up for recess.
3. The bell rang, Jamal closed his book and lined up for recess.
4. Although the bell rang, Jamal closed his book and lined up for recess.

Explanation: Choice A joins the two ideas smoothly with the word "When" and keeps everything the sentences said, so it is correct. Choice B drops the detail about closing the book and changes the meaning, Choice C is a comma splice that joins two sentences with only a comma, and Choice D uses "Although," which wrongly suggests a contrast that was not in the original.

Question 20

1. Although the science fair was exciting, it was quiet and empty all day.
2. The science fair was busy and loud, so it felt exciting to Emma. (correct answer)
3. The science fair was busy, and the science fair was loud, and the science fair was exciting.
4. The science fair was busy, the science fair was loud, the science fair was exciting.

Explanation: The best revision combines the three short sentences smoothly and adds variety: "The science fair was busy and loud, so it felt exciting to Emma." Choice B does that, so it is correct. Choice A wrongly says it was "quiet and empty," Choice C just repeats "the science fair was," and Choice D is a comma splice, so none improves the flow as well.
