Question 1

1. a kind person who enjoys nature. (correct answer)
2. a professional ornithologist studying birds.
3. someone who dislikes having birds near her home.
4. attempting to capture and sell the sparrows.

Explanation: When you encounter inference questions on the HSPT reading exam, you need to read between the lines and draw logical conclusions based on the evidence provided, rather than looking for directly stated information. Let's examine what Mrs. Gable's actions reveal about her character. The passage shows that when a sparrow begins tapping on her window, she responds by leaving out seeds for it. This is a caring, nurturing response that demonstrates kindness toward wildlife. Her continued feeding leads to more birds visiting, and there's no indication she's bothered by this development. These actions strongly suggest she's a kind person who enjoys nature, making choice A correct. Choice B is wrong because there's no evidence Mrs. Gable is studying the birds professionally. She's simply feeding them, not conducting research or taking scientific observations. Choice C contradicts the passage entirely—if she disliked birds near her home, she wouldn't feed them and encourage more to come. Choice D makes no sense given the context; she's providing free food to attract birds, which is the opposite of trying to capture them for profit. The key trap here is confusing what's directly stated versus what can be reasonably inferred. Mrs. Gable's kindness isn't explicitly mentioned, but her generous actions toward the sparrows clearly demonstrate this trait. For HSPT inference questions, focus on character actions and their logical implications. What someone does often reveals more about their personality than what they say, so pay close attention to behavioral evidence when drawing conclusions about character traits.

Question 2

1. believes his team lacks talented players.
2. values cooperation more than individual achievement. (correct answer)
3. plans to replace the team's top scorer soon.
4. thinks passing drills are the only way to win.

Explanation: When you encounter reading comprehension questions asking what can be "logically concluded," you need to identify what the evidence directly supports, not what might be possible or what requires assumptions beyond the text. The coach's actions consistently demonstrate that he prioritizes team cooperation over individual performance. He opens by stating that "teamwork" wins championships, dedicates more practice time to "passing drills and team-based strategies" rather than individual skills, and directly tells the top scorer that "a single player cannot win a game alone." This pattern of words and actions clearly shows he values cooperation more than individual achievement, making B correct. Let's examine why the other options don't work: A is wrong because the coach acknowledges that "talent is important" - he doesn't suggest his team lacks talented players, just that talent alone isn't enough. C makes an unsupported leap; disagreeing with a player about practice priorities doesn't indicate plans to replace them. D uses extreme language ("only way") that the passage doesn't support - the coach emphasizes passing drills and teamwork but never claims these are the only methods for winning. On HSPT reading questions, watch for answer choices that go beyond what the text actually supports. The correct conclusion will be directly backed by evidence from the passage, while wrong answers often include extreme language, unsupported assumptions, or details that sound plausible but aren't actually stated or implied by the text.

Question 3

1. It caused sundials and hourglasses to become illegal to own.
2. It made people less reliant on the weather for daily scheduling. (correct answer)
3. It was initially very unpopular with the general public.
4. It was less accurate than the water clocks that came before it.

Explanation: When you encounter reading comprehension questions asking about effects or implications, look for what the passage directly states or strongly suggests, rather than making large assumptions. The passage explains that early timekeeping methods like sundials were "dependent on specific conditions like sunny weather," meaning people had to wait for good weather to accurately tell time. When the pendulum clock was invented, it provided "a level of accuracy previously unimaginable" without these weather dependencies. This strongly suggests that people became less reliant on weather conditions for managing their daily schedules, making choice B correct. Let's examine why the other options don't work: Choice A claims sundials and hourglasses became "illegal to own," but the passage never mentions any legal restrictions—it only discusses the superior accuracy of pendulum clocks. Choice C suggests the pendulum clock was "initially very unpopular," but the passage presents it as a positive "major leap forward" with no indication of public resistance. Choice D states it was "less accurate than water clocks," which directly contradicts the passage's claim that pendulum clocks offered unprecedented accuracy. For HSPT reading questions about cause and effect, focus on what the passage explicitly supports rather than extreme conclusions. The test often includes distractors that go too far beyond what's stated (like making something "illegal") or that directly contradict the passage. Stick to logical inferences that flow naturally from the given information.

Question 4

1. proud of his rapid progress with the violin.
2. bored and is looking for a new hobby to try.
3. angry at his grandfather for giving him the violin.
4. discouraged by the difficulty of learning the instrument. (correct answer)

Explanation: When you encounter inference questions on reading passages, you need to look beyond what's directly stated and use context clues to understand the character's emotional state. Pay attention to descriptive language, actions, and comparisons the author makes. The passage provides several key clues about Samuel's feelings. His fingers "still felt clumsy" after six months of lessons, and he produces "screechy" sounds rather than music. Most telling is the contrast between his disappointing performance and his memory of his grandfather "filling the house with beautiful, soaring melodies." The passage ends with Samuel sighing and putting the violin away – actions that signal frustration and disappointment. This evidence points to answer D: Samuel feels discouraged by the difficulty of learning the instrument. Looking at the wrong answers: A is incorrect because Samuel is clearly not proud – the word "still" emphasizes his ongoing struggles rather than progress. B misses the emotional connection Samuel has to the violin; he's not bored but rather invested in honoring his grandfather's memory. C is wrong because there's no anger toward his grandfather – instead, Samuel fondly remembers his grandfather's beautiful playing. For inference questions, always look for emotional indicators like sighs, body language, and contrasting descriptions. The HSPT often tests your ability to read between the lines by having characters express feelings through actions rather than direct statements. Focus on the overall mood the author creates rather than isolated details.

Question 5

1. has proven that dragons once existed.
2. is less accurate than ancient cultural beliefs.
3. can replace superstitious explanations with natural ones. (correct answer)
4. is the main cause of supernatural events.

Explanation: When you encounter reading questions that contrast old beliefs with modern understanding, focus on identifying what the passage suggests about the relationship between these different ways of explaining phenomena. The passage presents a clear before-and-after comparison: ancient cultures used supernatural explanations for solar eclipses (dragons, angry gods), while scientists today understand eclipses as predictable natural events caused by celestial alignment. The key phrase is that scientists "can now predict the exact time and path" and "understand it as a natural alignment" — this shows scientific knowledge replacing supernatural beliefs with natural explanations. Choice C correctly captures this progression from superstitious to scientific understanding. The passage demonstrates exactly this replacement: supernatural explanations gave way to natural, predictable ones. Choice A misreads the passage entirely — nowhere does it suggest dragons actually existed. The passage treats dragon explanations as cultural beliefs, not historical facts. Choice B contradicts the passage's clear implication that scientific understanding is superior, as evidenced by scientists' ability to make precise predictions years in advance. Choice D reverses the relationship — the passage shows science explaining supernatural beliefs, not causing supernatural events. For HSPT reading questions, pay attention to implied relationships between ideas rather than just stated facts. When passages contrast past and present understanding, the test often asks you to identify what this suggests about progress, accuracy, or the nature of knowledge. Focus on the author's implied judgment about which approach is more reliable or effective.

Question 6

1. They were seen as a dangerous nuisance.
2. Their presence was viewed as a special and welcome event. (correct answer)
3. Most people in the town were indifferent to them.
4. They were considered a threat to the town's water supply.

Explanation: When you encounter inference questions on the HSPT reading exam, you need to look for clues in the text that reveal attitudes or feelings that aren't directly stated. The key is finding evidence that supports logical conclusions about what people think or feel. Looking at this passage, several details reveal the community's positive attitude toward the eagles. First, the newspaper gave the story front-page coverage, suggesting it was considered newsworthy and important. Second, birdwatchers flocked to see them, indicating public interest and excitement. Most significantly, the town council postponed a construction project to avoid disturbing the birds, showing they prioritized the eagles' welfare over their own plans. These actions collectively demonstrate that the community viewed the eagles as something special worth protecting and celebrating. Choice A is wrong because nothing suggests the eagles were seen as dangerous or problematic. Choice C contradicts the evidence of widespread community engagement and media attention. Choice D has no support in the text—there's no mention of water supply concerns or any perceived threat to the reservoir's function. The correct answer is B because all the evidence points to the eagles being "viewed as a special and welcome event"—the front-page story, the influx of interested birdwatchers, and especially the council's willingness to delay their own project. For inference questions, always look for concrete actions and decisions that reveal underlying attitudes. What people do often tells you more about their feelings than what they explicitly say.

Question 7

1. getting lost while traveling to other neighborhoods.
2. experiencing boredom due to a lack of restaurants.
3. paying lower prices for their groceries on average.
4. developing health problems related to poor nutrition. (correct answer)

Explanation: When you encounter reading comprehension questions that ask what can be "inferred," you're being tested on your ability to draw logical conclusions from the given information, even when those conclusions aren't explicitly stated in the passage. The passage describes food deserts as areas lacking access to affordable, quality fresh food, with residents relying heavily on fast-food restaurants and convenience stores that offer "few healthy options." When people consistently lack access to fresh fruits, vegetables, and whole foods, the logical consequence is poor nutrition, which leads to health problems like obesity, diabetes, and heart disease. This makes choice D correct. Let's examine why the other options don't follow logically from the passage. Choice A focuses on getting lost while traveling, but the passage mentions travel distance as a barrier to accessing food, not navigation difficulties. Choice B suggests boredom from lack of restaurants, but food deserts actually have "an abundance of fast-food restaurants" – the problem is food quality, not quantity of dining options. Choice C claims lower grocery prices, but this contradicts the passage's emphasis on difficulty finding "affordable" fresh food, suggesting residents actually face higher costs for quality nutrition. For HSPT reading inference questions, remember that the correct answer should be a logical consequence that flows naturally from the passage's facts. Avoid choices that introduce new concepts not supported by the text, like navigation problems or restaurant variety, and focus on what the described situation would realistically cause.

Question 8

1. She did not like the friends who were at the party.
2. She is likely an introverted person. (correct answer)
3. She is always dishonest about her feelings.
4. She prefers walking to all other forms of travel.

Explanation: When you encounter inference questions about character traits, look for patterns in the character's actions and reactions that reveal deeper personality tendencies. The passage provides key clues about Maria's personality through her behavior and emotional responses. She leaves the party because "loud music and crowded rooms were making her feel overwhelmed," and she experiences "relief" when alone in the quiet evening air. This pattern—discomfort in stimulating social environments and comfort in solitude—strongly suggests introversion. Introverts typically find large, noisy gatherings draining and need quiet time to recharge, which matches Maria's experience perfectly. Choice A is incorrect because there's no evidence Maria dislikes her friends. She tells them she's not feeling well rather than making excuses about them, suggesting she maintains positive relationships. Choice C misinterprets her partial truth as habitual dishonesty, but the passage shows she's being considerate by giving a simpler explanation rather than lying completely. Choice D makes an unsupported leap—while Maria walks home, this single instance doesn't indicate a general preference for walking over other transportation. For HSPT reading inference questions, focus on what the evidence directly supports rather than making assumptions. Look for behavioral patterns that consistently point toward a particular trait, and avoid answer choices that go beyond what's actually demonstrated in the passage. The strongest inferences come from multiple pieces of evidence working together, like Maria's overwhelm in crowds plus her relief in solitude.

Question 9

1. the club's new, more experienced faculty advisor.
2. a change in the school's policy on extracurriculars.
3. a winning streak by the school's competitive team.
4. the influence of a recent piece of popular culture. (correct answer)

Explanation: When you encounter reading comprehension questions asking about cause and effect, look for explicit connections the passage makes between events. The key is identifying what the text directly states or strongly implies as the reason for a change. The passage establishes a clear sequence: the chess club was small and quiet, then a popular movie about a young chess prodigy was released, and immediately afterward ("the following week") membership tripled. The new members were discussing "strategies they had seen in the movie," which directly connects their interest to the film. This chain of events makes the movie the primary cause of increased membership, making D correct. Let's examine why the other options fail. Choice A mentions a new faculty advisor, but the passage never discusses any advisor, experienced or otherwise. Choice B suggests a policy change regarding extracurriculars, but again, no school policy changes are mentioned or implied in the text. Choice C proposes that a winning streak attracted new members, but the passage provides no information about the team's competitive performance or any wins. Each incorrect option introduces information that simply isn't present in the passage—a common trap in reading comprehension questions. For HSPT reading questions about cause and effect, stick closely to what the passage explicitly states. Don't bring in outside assumptions about what might logically cause membership increases. The test rewards you for finding evidence directly in the text, not for making reasonable but unsupported inferences.

Question 10

1. to make the city's skyline more beautiful.
2. to create more jobs for local gardeners.
3. to address environmental and energy issues. (correct answer)
4. to lower the cost of constructing new buildings.

Explanation: When you encounter reading comprehension questions asking what a passage "implies," you need to look for the underlying reasons or motivations that aren't explicitly stated but can be reasonably inferred from the evidence provided. The passage presents two key pieces of evidence about green roofs: they reduce energy consumption for cooling by up to 20 percent, and they help manage storm water runoff, which is described as "a major problem" in the city. These benefits directly point to environmental concerns (managing runoff pollution and reducing energy use) and practical energy efficiency issues. Therefore, choice C correctly identifies that the ordinance addresses environmental and energy issues. Looking at the wrong answers: Choice A suggests aesthetic motivation, but the passage focuses entirely on functional benefits rather than visual appeal. Choice B assumes job creation is the goal, but gardeners aren't even mentioned in the passage. Choice D implies cost reduction for construction, but green roofs would likely increase building costs initially—the savings mentioned are operational energy costs, not construction expenses. Notice that the question asks for the "primary motivation," meaning you need to identify what drove the council's decision based on the evidence they considered. The study they reviewed highlighted environmental and energy benefits, making these the logical driving forces behind the ordinance. Strategy tip: For implication questions, stick closely to what the text supports. Don't choose answers that might be true in real life but aren't supported by the specific evidence the passage provides.

Question 11

1. prolonged exposure to the desert climate. (correct answer)
2. an inability to find sufficient food sources.
3. a lack of other animals to share its burrow.
4. the difficulty of digging burrows in hard soil.

Explanation: When you encounter reading comprehension questions that ask what a passage "suggests" about threats or challenges, you need to make inferences based on the adaptations or behaviors described, rather than looking for directly stated information. The passage describes three key adaptations of the desert tortoise: surviving over a year without water by getting moisture from plants, spending most of its time in underground burrows to escape extreme heat, and digging burrows up to 30 feet long. These adaptations all point to one major challenge: surviving the harsh desert climate. The tortoise's entire lifestyle revolves around avoiding heat and conserving water, which indicates that prolonged exposure to desert conditions would be its greatest threat. Choice A is correct because the tortoise's primary adaptations (water conservation, underground shelter) are specifically designed to counter the desert's extreme climate conditions. Choice B is incorrect because the passage indicates the tortoise successfully derives moisture from plants, suggesting food sources are adequate rather than threatening. Choice C misses the point entirely—the passage mentions burrow-sharing as a neutral fact, not as something essential for the tortoise's survival. Choice D focuses on a minor logistical detail rather than a survival threat. The passage presents the tortoise's digging ability as a successful adaptation, not a struggle. Remember: when a passage describes multiple adaptations, ask yourself what environmental challenge these adaptations are designed to overcome. The most extensive adaptations usually point to the greatest threat.

Question 12

1. taught by older butterflies to the younger generation.
2. an inherited or instinctual trait, not a learned one. (correct answer)
3. dependent on following the same route as their parents.
4. a new phenomenon that has only recently been observed.

Explanation: When you encounter reading comprehension questions about animal behavior, look for clues about whether a behavior is learned or instinctual. The key evidence here lies in the timing and generational gap described in the passage. The passage tells us that "no single butterfly completes a round trip" and that the butterflies making each journey are "several generations removed" from those who made the previous trip. Despite this generational separation, they still navigate to "the exact same location." This strongly suggests the navigational ability must be inherited rather than learned, since there's no opportunity for direct teaching between generations. Choice A is incorrect because older butterflies cannot teach younger ones when they're separated by several generations and never make the return trip. Choice C fails because the butterflies aren't following their parents—their parents are long gone by the time they make the journey. Choice D misreads the passage entirely; nothing suggests this is a new phenomenon, and the word "every" implies this happens regularly. Choice B correctly identifies that this navigational ability must be inherited or instinctual. The butterflies somehow "know" where to go without any prior experience or guidance, which points to genetic programming rather than learned behavior. When tackling HSPT reading questions about animal behavior, pay attention to words that signal whether knowledge could realistically be passed down through learning. Phrases like "several generations removed" or "never meet" are strong indicators that you're dealing with inherited traits rather than learned behaviors.

Question 13

1. believed the community could influence the city's decision. (correct answer)
2. were responsible for the city's budget cuts.
3. wanted to get summer jobs at the new car wash.
4. thought the swimming pool was unsafe and should be closed.

Explanation: When you encounter inference questions on reading passages, you're looking for conclusions that must be true based on the evidence provided, even if not directly stated. The key is to follow the logical chain of actions and motivations. The teenagers' behavior reveals their underlying belief system. They organized a fundraising effort specifically to "Save Our Pool" and donated all proceeds to the city's parks department. This sequence of actions only makes sense if they believed their community fundraising could influence the city's budget decision. Their sign and sustained effort over multiple Saturdays demonstrate they thought collective action could make a difference. Therefore, answer A is correct—the teenagers believed the community could influence the city's decision. Looking at the wrong answers: B suggests the teenagers caused the budget cuts, but the passage clearly states the city made cuts due to budget constraints, with no indication the teenagers were responsible. C misinterprets their motivation—they weren't seeking employment but rather trying to save their pool through fundraising. D contradicts their entire effort; if they thought the pool was unsafe and should close, they wouldn't have organized a campaign to save it. For HSPT reading inference questions, always ask yourself: "What must be true for these characters to act the way they did?" The characters' actions and words reveal their beliefs and motivations. Avoid answers that require information not provided in the passage or that contradict the characters' demonstrated goals.

Question 14

1. unpopular and caused fewer students to participate.
2. ineffective at changing students' reading habits.
3. successful in encouraging students to explore new topics. (correct answer)
4. designed to make the challenge much more difficult.

Explanation: When you encounter reading comprehension questions that ask what a passage "suggests," you're looking for conclusions you can reasonably draw from the evidence provided, even if not explicitly stated. The passage gives us clear evidence about the new rule's impact: librarians reported "a surge in the checkout of books from the history, poetry, and science fiction sections by young readers." This directly indicates that students responded to the requirement by exploring genres they hadn't tried before. The word "surge" suggests a significant increase, pointing to the rule's success in achieving its apparent goal of broadening reading habits. Choice A is incorrect because there's no evidence of unpopularity or decreased participation. The passage only mentions positive outcomes. Choice B contradicts the evidence entirely—the surge in diverse genre checkouts shows the rule was quite effective at changing reading habits. Choice D focuses on difficulty, but the passage doesn't suggest the rule made the challenge harder to complete, only that it encouraged different book selections. The correct answer is C because the evidence (increased checkouts of previously unexplored genres) directly supports the conclusion that the new rule successfully encouraged exploration of new topics. For HSPT reading questions asking what a passage "suggests" or "implies," always look for concrete evidence in the text that supports your conclusion. Avoid answers that contradict the evidence or introduce ideas not supported by the passage. The key is connecting the dots between what's stated and what logically follows.

Question 15

1. a potential inconsistency in the candidate's promises. (correct answer)
2. a popular aspect of the candidate's political platform.
3. the candidate's detailed knowledge of the city budget.
4. the journalist's personal support for the candidate.

Explanation: When you encounter reading comprehension questions about what a passage "implies," you're being asked to make logical inferences from the information given, not just identify directly stated facts. The journalist's question exposes a logical problem in the candidate's platform. The candidate promises both to lower taxes (reducing government revenue) and to improve schools (which typically requires increased spending). When pressed on how he would accomplish both simultaneously, the candidate gives only a vague response about "eliminating wasteful spending" without specifics. This reveals that his promises may be contradictory or at least poorly planned. Choice A is correct because the journalist's probing question highlighted this potential inconsistency between reduced revenue and increased spending promises. Choice B is wrong because the journalist's question wasn't about popularity—it was challenging the feasibility of the promises. Choice C is incorrect because the candidate's vague response actually suggests a lack of detailed budget knowledge, not expertise. Choice D misses the mark entirely; the journalist's challenging question shows professional skepticism, not personal support. For HSPT reading questions about implications, look for the logical connections between ideas that aren't explicitly stated. The author often presents information that allows you to draw reasonable conclusions about contradictions, motivations, or underlying meanings. Practice identifying when details in a passage create tension or reveal something deeper about a character or situation.

Question 16

1. the need for individual, focused work. (correct answer)
2. the employees' desire for higher salaries.
3. the architectural design of the building.
4. the company's official dress code policy.

Explanation: When you encounter inference questions asking about conflicts or contradictions, look for what the passage suggests indirectly rather than what it states outright. The key is identifying opposing forces or unintended consequences. The passage describes a classic workplace dilemma: the company wanted to boost collaboration by removing cubicle walls, but this created an unexpected problem. While communication did increase as intended, employees became "more distracted and less productive" and dramatically increased their use of noise-canceling headphones. This evidence points to workers struggling to concentrate in the new environment. Answer A correctly identifies this conflict—the open office succeeded in promoting collaboration but interfered with employees' ability to do focused, individual work. The rise in headphone use is a clear signal that people were trying to create artificial barriers to block out distractions. Answer B is wrong because salary concerns aren't mentioned anywhere in the passage. Answer C misses the mark because there's no conflict with the building's architecture itself—the floor plan change was intentional and successfully implemented. Answer D is completely irrelevant since dress code policies have nothing to do with office layout or the described problems. For HSPT reading inference questions, pay attention to unintended consequences and contradictory outcomes. When a passage describes a plan that partially backfires, the test often asks you to identify what competing need or goal was overlooked. Look for clue words like "however," "but," and "while" that signal conflicting results.

Question 17

1. the invention of the pizza delivery service.
2. a government campaign to promote Italian food.
3. cultural exposure through military service abroad. (correct answer)
4. a sudden decrease in the price of cheese and flour.

Explanation: When you encounter reading comprehension questions that ask what a passage "implies," you're looking for information that isn't directly stated but can be logically inferred from the evidence provided. The passage tells us that pizza remained niche for decades until "American soldiers returned from Italy after World War II, bringing with them a taste for the dish" and then "its popularity began to skyrocket across the entire country." This creates a clear cause-and-effect relationship: military service in Italy exposed soldiers to pizza, they brought this appreciation home, and pizza's popularity exploded nationally. This directly supports answer choice C - cultural exposure through military service abroad was the major factor in pizza's national popularization. Looking at the incorrect options: Answer choice A mentions pizza delivery service, but the passage doesn't discuss delivery methods at all. Answer choice B suggests a government campaign, but there's no mention of any official promotion of Italian food. Answer choice D proposes economic factors like cheaper ingredients, but the passage focuses entirely on cultural exposure and taste preferences, not pricing. The key word "implies" signals that you need to make a reasonable inference based on the evidence presented. The passage establishes a timeline and causal relationship between soldiers' overseas experience and pizza's subsequent popularity boom. On reading comprehension questions, always look for the answer choice that has the strongest textual support, even when making inferences. The correct answer should feel like a natural, logical extension of what's explicitly stated in the passage.

Question 18

1. quickly finish grading all of the papers.
2. make students feel bad about their writing.
3. show off his knowledge of grammar rules.
4. encourage students to think more deeply. (correct answer)

Explanation: When you encounter inference questions on the HSPT reading exam, you need to read between the lines to understand what the author suggests but doesn't directly state. Look for patterns in the evidence provided. The passage gives us specific clues about Mr. Harrison's teaching approach. Notice that instead of simple praise like "Good job!" he asks probing questions: "Can you provide a specific example here?" and "How does this sentence support your main argument?" These questions don't just point out errors—they guide students to analyze and strengthen their own thinking. This pattern suggests his primary goal is to encourage deeper reflection, making D correct. Let's examine why the other choices miss the mark. Choice A assumes he wants to grade quickly, but asking thoughtful questions actually takes more time than simple corrections. Choice B might seem tempting since students feel nervous, but nervousness doesn't equal intentional cruelty—his questions are constructive, not mean-spirited. Choice C suggests he's showing off grammar knowledge, but the examples given focus on content and reasoning, not grammar rules. For HSPT inference questions, remember this strategy: distinguish between what characters feel versus what they intend. Students may feel nervous about Mr. Harrison's green pen, but his actual questions reveal his true purpose—developing their critical thinking skills. Always look for evidence of motivation in a character's specific actions and words, not just in others' reactions to them.

Question 19

1. add more water to speed up decomposition.
2. cover the pile with a plastic tarp to trap the smell.
3. turn the pile to introduce more oxygen. (correct answer)
4. assume that the composting process is working correctly.

Explanation: Reading comprehension questions often test your ability to make logical connections between a problem described in the passage and its most reasonable solution. When you encounter a cause-and-effect scenario like this one, look for clues about what's going wrong and what would logically fix it. The passage explains that bad smells from compost indicate "too much moisture and not enough air, creating an anaerobic condition." The key word here is "anaerobic," which means without oxygen. If the problem is lack of air/oxygen, the solution should involve adding more air to the pile. Choice C is correct because turning the pile would introduce oxygen and improve air circulation, directly addressing the root cause of the problem. This would restore the proper aerobic (oxygen-rich) conditions needed for healthy decomposition. Choice A suggests adding water, but the passage specifically states that too much moisture is part of the problem, so this would make things worse. Choice B recommends covering with plastic, which would trap moisture and further restrict airflow—exactly the opposite of what's needed. Choice D assumes the smell indicates normal composting, but the passage clearly states that a well-managed pile "should not produce strong, unpleasant odors." When tackling HSPT reading questions, always trace the logical chain: identify the problem the passage describes, understand its cause, then select the answer that directly addresses that cause. Don't be tempted by choices that seem related to the topic but don't actually solve the specific issue presented.

Question 20

1. It intentionally makes its instructions difficult to save money.
2. It is unaware that customers find the instructions challenging.
3. It is a new company that has not yet written instructions.
4. It has invested in customer support to address assembly problems. (correct answer)

Explanation: When you encounter an inference question, you need to look for what the passage suggests without explicitly stating. The key is finding evidence that supports a logical conclusion about what's happening behind the scenes. The passage reveals that Mark struggled with poorly designed instructions but "was immediately connected to a representative who patiently walked him through the final steps." This sequence suggests the company recognizes assembly problems and has prepared for them. The fact that customer service could immediately help with assembly steps indicates they're trained and equipped to handle these specific issues—a sign of deliberate investment in support resources. Choice A assumes malicious intent to save money, but there's no evidence the difficulty is intentional. Choice B suggests the company is unaware of the problem, but their prepared customer service response proves they know customers struggle with assembly. Choice C makes an unsupported assumption about the company being new—the passage gives no information about the company's age or history. Choice D correctly identifies what the evidence points to: the company has invested in customer support specifically to address assembly difficulties. The immediate connection and the representative's patient, knowledgeable assistance suggest a well-developed support system designed to compensate for the challenging instructions. For HSPT reading inference questions, always distinguish between what you can prove from the text versus assumptions you might make. Look for the choice that has the strongest textual support, even if other options seem plausible. The correct inference will always have clear evidence pointing toward it.
