Question 1

When the teacher finally paused, Tatiana ventured a tentative suggestion, fully aware that her idea might be dismissed.

In the sentence above, what does the word "tentative" most nearly mean?

  1. bold and forceful
  2. uncertain and cautious (correct answer)
  3. fully prepared
  4. lengthy and detailed
Explanation: When you encounter vocabulary-in-context questions on the TACHS reading exam, you need to use the surrounding words and situation to determine the meaning of the unfamiliar word, rather than relying on memorized definitions. Let's examine the clues in this sentence. Tatiana "ventured" her suggestion only after the teacher "finally paused," suggesting she was waiting for the right moment. Most importantly, she was "fully aware that her idea might be dismissed." This shows she's uncertain about how her suggestion will be received and is proceeding carefully. The word "tentative" describes how she offered her suggestion—with hesitation and caution. Choice B, "uncertain and cautious," perfectly captures this meaning. Someone making a tentative suggestion is testing the waters carefully, unsure of the response they'll receive. Choice A, "bold and forceful," is the opposite of tentative. If Tatiana were being bold, she wouldn't wait for a pause or worry about dismissal. Choice C, "fully prepared," doesn't fit because being tentative suggests doubt, not confidence in one's preparation. Choice D, "lengthy and detailed," describes the content or format of a suggestion, not the manner in which it's offered. Study tip: For vocabulary questions, always look for context clues in the same sentence and surrounding sentences. Words like "fully aware that her idea might be dismissed" are huge hints about the character's emotional state and approach. Practice identifying these emotional and behavioral signals—they're your best tools for determining word meaning on the TACHS.

Question 2

Grandmother's stories were rich with vivid descriptions that evoked the bustling markets of her youth.

The word "evoked" in the sentence most nearly means

  1. commented on in passing
  2. brought to mind (correct answer)
  3. ignored entirely
  4. purchased cheaply
Explanation: This question tests your ability to determine word meaning from context clues, a crucial reading comprehension skill. When you encounter an unfamiliar word or need to choose the best meaning, look at the surrounding words and the overall sentence structure for hints. The key context clues here are "Grandmother's stories were rich with vivid descriptions" and "the bustling markets of her youth." The sentence structure tells us that the vivid descriptions did something to these markets from her past. Since we're talking about stories and descriptions, the word "evoked" must describe how these descriptions affected the listener's mind. Choice B, "brought to mind," fits perfectly. When grandmother told stories with vivid descriptions, those descriptions brought the bustling markets to mind for her listeners. This makes logical sense with storytelling. Choice A, "commented on in passing," suggests something casual or brief, which contradicts "rich with vivid descriptions." Choice C, "ignored entirely," makes no sense since the sentence emphasizes that the stories were rich with these descriptions. Choice D, "purchased cheaply," is completely unrelated to storytelling and descriptions. When tackling vocabulary-in-context questions on the TACHS, always substitute each answer choice back into the original sentence to see which one maintains the logical flow and meaning. Don't rely on your prior knowledge of the word alone—the context of the passage should guide you to the answer that best fits the author's intended meaning.

Question 3

Seeing the broken vase, Leo offered a contrite apology to his sister.

The word "contrite" most nearly means

  1. mildly amused
  2. deeply sorry (correct answer)
  3. completely confused
  4. delighted and proud
Explanation: When you encounter vocabulary questions on the TACHS reading exam, use context clues from the sentence to help determine the word's meaning. The situation described here provides strong hints about Leo's emotional state. The context shows Leo seeing a broken vase and then apologizing to his sister. This sequence suggests Leo likely broke the vase (either accidentally or intentionally) and feels bad about it. When someone damages another person's property, a sincere, remorseful apology would be expected and appropriate. The word "contrite" means deeply sorry or genuinely remorseful, making choice B correct. Leo's apology reflects true regret for what happened to his sister's vase. Choice A (mildly amused) makes no sense in this context - being amused while apologizing for breaking someone's property would be inappropriate and contradictory. Choice C (completely confused) doesn't fit because Leo clearly understands what happened; there's no indication of confusion about the broken vase or the need to apologize. Choice D (delighted and proud) is completely opposite to what the situation calls for - feeling happy about breaking someone else's belongings would be callous and strange. When tackling vocabulary questions, always examine the surrounding context carefully. Look for emotional cues, cause-and-effect relationships, and logical connections between events. The tone and situation in the sentence will often guide you toward the correct meaning, even if you've never encountered the word before. Practice identifying these contextual clues to improve your vocabulary question performance.

Question 4

The detective was known for his uncanny ability to notice clues that others overlooked.

What is the meaning of "uncanny" as used in the sentence?

  1. poorly rehearsed
  2. completely accidental
  3. strangely remarkable (correct answer)
  4. politely restrained
Explanation: When you encounter vocabulary questions asking for word meaning, use context clues from the surrounding sentence to guide your understanding. The key phrase here is "ability to notice clues that others overlooked" - this describes something impressive and unusual about the detective's skills. The word "uncanny" means mysteriously skillful or strangely remarkable - beyond what seems normal or expected. In this context, it emphasizes that the detective's observational abilities are so extraordinary they seem almost supernatural. This makes choice C, "strangely remarkable," the correct answer, as it captures both the unusual nature and the impressive quality of the detective's talent. Let's examine why the other options don't work. Choice A, "poorly rehearsed," suggests something unprepared or sloppy, which contradicts the positive description of the detective's exceptional abilities. Choice B, "completely accidental," implies the detective succeeds by chance rather than skill, which doesn't align with describing an "ability" - abilities are developed talents, not accidents. Choice D, "politely restrained," describes mannerly or controlled behavior, which has nothing to do with the detective's observational skills or the context of finding overlooked clues. For vocabulary questions on the TACHS, always read the entire sentence carefully and look for context clues that reveal the word's meaning. Words like "ability" and phrases describing what others cannot do often signal that you're looking for a word with positive, exceptional connotations. Don't be misled by unfamiliar-sounding answer choices that don't fit the sentence's logic.

Question 5

During the storm, the lighthouse stood as a steadfast beacon for sailors navigating the treacherous waters.

Here, the word "steadfast" most nearly means

  1. recently constructed
  2. brief but bright
  3. hidden from view
  4. firm and reliable (correct answer)
Explanation: When you encounter vocabulary-in-context questions, you need to use the surrounding words and situation to determine what the word means in that specific passage, rather than relying on memorized definitions. In this passage, the lighthouse is described during a storm as a "beacon for sailors navigating treacherous waters." The context tells us that sailors are in dangerous conditions and need guidance. A lighthouse that serves as a beacon in such circumstances must be dependable and unwavering. The word "steadfast" describes how the lighthouse maintains its function despite the challenging storm conditions, making choice D) "firm and reliable" the correct answer. Let's examine why the other options don't fit. Choice A) "recently constructed" has nothing to do with the lighthouse's behavior during the storm - the age of the structure is irrelevant to its role as a beacon. Choice B) "brief but bright" contradicts the context since sailors need consistent, not temporary, guidance during dangerous weather. Choice C) "hidden from view" makes no sense because a lighthouse that's hidden couldn't function as a beacon to guide sailors. For vocabulary questions on the TACHS, always read the entire sentence and consider what role the unknown word plays in the situation being described. The context clues - like "storm," "beacon," and "treacherous waters" - will guide you toward the meaning that makes logical sense in that specific scenario, even if the word might have different meanings in other contexts.

Question 6

After listening to the lengthy debate, the judge rendered a decision that was both judicious and fair.

As used in the sentence, "judicious" most nearly means

  1. excessively harsh
  2. hastily delivered
  3. mathematically precise
  4. wise and prudent (correct answer)
Explanation: When you encounter vocabulary-in-context questions, focus on how the word functions within the sentence and what clues the surrounding words provide about its meaning. The key context clues here are "judge rendered a decision" and the phrase "both judicious and fair." The word "judicious" is paired with "fair" using the word "both," which indicates these two qualities work together to describe the same type of decision. Since "fair" suggests impartiality and rightness, "judicious" must complement this meaning. Additionally, we expect judges to make thoughtful, well-reasoned decisions rather than rash or harsh ones. Choice D, "wise and prudent," perfectly captures this meaning. A judicious decision is one made with careful thought, good judgment, and wisdom—exactly what we'd want from a judge after a lengthy debate. Choice A, "excessively harsh," contradicts the positive tone established by pairing "judicious" with "fair." Harsh decisions aren't typically described as fair. Choice B, "hastily delivered," directly opposes the context—the judge listened to a "lengthy debate" before deciding, suggesting careful consideration rather than haste. Choice C, "mathematically precise," doesn't fit because legal decisions involve weighing evidence and applying judgment, not mathematical calculations. Remember that vocabulary-in-context questions test whether you can use surrounding clues to determine meaning, not just whether you know the word in isolation. Look for parallel words or phrases that work together, and consider what makes logical sense given the situation described.

Question 7

Rising early each day became habitual for Carla, a routine so ingrained that she barely noticed the alarm.

What does "ingrained" mean in this context?

  1. dangerously risky
  2. recently attempted
  3. socially approved
  4. deeply established (correct answer)
Explanation: When you encounter vocabulary-in-context questions, focus on how the surrounding words and sentences provide clues about the word's meaning. The passage tells us that Carla's early rising became "habitual" and was "a routine so ingrained that she barely noticed the alarm." The key phrase here is "so ingrained that she barely noticed" — this suggests something that has become automatic and deeply rooted in her behavior. The word "ingrained" means deeply established or firmly fixed, making D the correct answer. The context clues support this: something that's habitual and so automatic that you barely notice it must be deeply embedded in your routine. Let's examine why the other choices don't fit. Choice A, "dangerously risky," makes no sense in context — there's nothing in the passage suggesting Carla's morning routine poses any danger. Choice B, "recently attempted," contradicts the meaning entirely since the passage emphasizes how established and automatic her routine has become, not something new she's trying. Choice C, "socially approved," isn't supported by any context clues about society's opinion of her wake-up time. For vocabulary questions on the TACHS, always read the entire sentence and look for context clues that hint at the word's meaning. Words like "habitual," "routine," and phrases like "barely noticed" often signal that something has become automatic through repetition. Pay attention to these signal words — they're your roadmap to the correct definition.

Question 8

The speaker's analogy was so apt that the audience immediately grasped the complex concept.

The word "apt" most nearly means

  1. overly humorous
  2. well-suited (correct answer)
  3. completely new
  4. typographically correct
Explanation: When you encounter vocabulary-in-context questions, look for clues in the surrounding words that reveal the meaning. The key here is understanding how the analogy functions in the sentence. The sentence tells us that "the audience immediately grasped the complex concept" because of how the speaker's analogy was described. This cause-and-effect relationship is crucial. If an analogy helps people quickly understand something difficult, it must be particularly effective or fitting for the situation. The word "apt" means well-suited or appropriate. Choice B captures this perfectly. An apt analogy is one that fits the situation so well that it makes a complex idea suddenly clear to the audience. Choice A suggests "overly humorous," but nothing in the passage indicates the analogy was funny, and being humorous doesn't necessarily help people understand complex concepts. Choice C, "completely new," doesn't work because novelty alone wouldn't guarantee comprehension—in fact, unfamiliar comparisons might confuse rather than clarify. Choice D, "typographically correct," relates to proper formatting or printing, which has nothing to do with how effectively an analogy communicates ideas. The word "immediately" in the sentence reinforces that the analogy was perfectly chosen—it worked so well that understanding happened instantly. For vocabulary questions on the TACHS, always examine the entire sentence for logical relationships. Words like "because," "since," "so that," and "immediately" often signal cause-and-effect connections that will guide you to the correct meaning. The context will almost always provide the clues you need.

Question 9

Despite the company's public enthusiasm, insiders regarded the proposal with palpable anxiety.

Here, the word "palpable" most nearly means

  1. wildly exaggerated
  2. easily perceived (correct answer)
  3. financially motivated
  4. legally binding
Explanation: When you encounter vocabulary questions on the TACHS reading exam, context clues are your best tool for determining word meaning. Look at how the word functions within the sentence and what the surrounding words tell you about its meaning. In this passage, "palpable" modifies "anxiety," and the sentence creates a contrast between the company's "public enthusiasm" and how "insiders regarded the proposal." The word "Despite" signals this opposition. The insiders felt anxiety that was so strong it could be described as "palpable." The correct answer is B) easily perceived. "Palpable" literally means "able to be touched or felt," but it's commonly used figuratively to describe something so intense or obvious that it's almost tangible. The insiders' anxiety was so strong that others could easily sense or perceive it, even though the company was publicly enthusiastic. Let's examine why the other choices don't work. A) "wildly exaggerated" suggests the anxiety was overblown, but nothing in the context indicates exaggeration. C) "financially motivated" introduces a reason for the anxiety that isn't supported by the passage. D) "legally binding" makes no sense when describing an emotion like anxiety. For TACHS vocabulary questions, always use the context to guide your thinking rather than trying to recall isolated definitions. Pay special attention to contrast words like "despite," "however," and "although" – they often signal that you need to understand opposing ideas to grasp the word's meaning in context.

Question 10

Although the novel is replete with complex themes, its language remains accessible to young readers.

The word "replete" in the sentence most nearly means

  1. carefully restricted
  2. filled to capacity (correct answer)
  3. surprisingly brief
  4. poorly organized
Explanation: Vocabulary questions on the TACHS often test words that might be unfamiliar but can be decoded through context clues and word relationships. When you encounter "replete," look at how it's used in the sentence structure. The sentence creates a contrast using "Although" - it sets up the idea that despite one characteristic of the novel, another characteristic remains true. The novel is "replete with complex themes" BUT its language stays accessible. This contrast suggests that having many complex themes would normally make something difficult to read, but this novel manages to remain readable anyway. The word "replete" describes the novel's relationship with complex themes. Given the contrasting structure, "replete" must mean the novel has an abundance of these themes - so much so that you'd expect the language to be difficult. Choice B, "filled to capacity," captures this meaning of being completely full or abundantly supplied with something. Choice A, "carefully restricted," contradicts the contrast structure since having few themes wouldn't create reading difficulty. Choice C, "surprisingly brief," doesn't make sense with "themes" - you can't have a brief amount of themes. Choice D, "poorly organized," doesn't fit the positive tone about the novel's accessibility and doesn't create the logical contrast the sentence establishes. When tackling vocabulary questions, always examine the sentence structure for clues. Words like "although," "however," and "despite" signal contrasts that can help you determine meaning even when you don't know the word.

Question 11

Far from being a trivial matter, the committee saw the oversight as a grievous error.

In this context, "grievous" most nearly means

  1. quickly forgotten
  2. serious and damaging (correct answer)
  3. mildly humorous
  4. financially neutral
Explanation: When you encounter vocabulary questions on the TACHS reading exam, context clues are your most powerful tool. Look at the surrounding words and phrases to understand how the unknown word functions in the sentence. The phrase "Far from being a trivial matter" immediately signals that whatever follows will be the opposite of trivial. Since trivial means unimportant or minor, you should expect "grievous" to mean something significant or major. The word "error" also suggests something negative and problematic. When a committee views an oversight as a "grievous error," they're treating it as something serious and harmful to their work or reputation. Choice A, "quickly forgotten," contradicts the emphasis the sentence places on the error's importance. If something is far from trivial, it's memorable and significant, not easily dismissed. Choice C, "mildly humorous," completely misreads the tone—committees don't treat errors as amusing, especially when they're described in such grave terms. Choice D, "financially neutral," introduces an irrelevant concept since nothing in the passage mentions money or financial impact. Choice B, "serious and damaging," perfectly captures both the gravity implied by "far from trivial" and the negative consequences suggested by calling it an "error" that demands the committee's attention. For TACHS vocabulary questions, always use contrast clues like "far from" or "rather than" to understand relationships between ideas. These signal words often point directly toward the correct meaning by showing you what the unknown word is not.

Question 12

The software update aims to mitigate the glitches users have been reporting.

The term "mitigate" in the sentence most nearly means

  1. predict accurately
  2. advertise widely
  3. duplicate exactly
  4. reduce the severity of (correct answer)
Explanation: This is a vocabulary-in-context question that tests your ability to determine word meaning from surrounding clues. When you encounter an unfamiliar word, look at the sentence structure and context to guide you toward the correct meaning. The key context clue here is "glitches users have been reporting." Software glitches are problems or errors that cause frustration. When a company releases an update specifically targeting these reported problems, the logical goal would be to lessen or reduce their impact. The word "mitigate" means to make less severe, intense, or painful—essentially to reduce the severity of something negative. Looking at the wrong answers: Choice A, "predict accurately," doesn't make sense because you can't predict glitches that users have already reported—they've already happened. Choice B, "advertise widely," is illogical since companies don't want to publicize their software problems. Choice C, "duplicate exactly," would mean recreating the glitches, which would be counterproductive for a software update meant to fix issues. Choice D correctly captures that the update aims to "reduce the severity of" the glitches, making them less problematic for users. For vocabulary questions like this, remember that context is your best friend. Look for clues in the surrounding words that indicate whether something positive or negative is happening, then choose the answer choice that logically fits that context. Words like "problems," "issues," or "glitches" often pair with solutions that reduce, fix, or eliminate them.

Question 13

Because the painting's provenance was unclear, experts hesitated to authenticate it.

In this context, "provenance" most nearly means

  1. public popularity
  2. monetary value
  3. artistic style
  4. record of origin (correct answer)
Explanation: Vocabulary-in-context questions test your ability to determine word meanings from surrounding clues rather than memorizing definitions. The key is to look at how the word functions within the sentence's logic. In this passage, the word "provenance" appears in a cause-and-effect relationship: "Because the painting's provenance was unclear, experts hesitated to authenticate it." This tells you that unclear provenance creates doubt about authenticity. Think about what information experts would need to confidently verify a painting's genuineness. The correct answer is D) record of origin. Art authentication requires knowing a painting's history—who owned it, where it came from, and how it can be traced back to the original artist. Without this documented chain of ownership and origin, experts cannot be certain the painting is genuine, which explains their hesitation. Looking at the wrong answers: A) public popularity wouldn't affect authentication since many authentic masterpieces aren't widely known, while popular works can be forgeries. B) monetary value doesn't determine authenticity—experts authenticate first, then determine value, not the other way around. C) artistic style being unclear wouldn't make experts hesitate to authenticate, since they're trained to analyze various styles and even identify works in unfamiliar styles. When tackling vocabulary-in-context questions, always substitute each answer choice back into the sentence to see which one maintains the logical relationship between ideas. The word that preserves the cause-and-effect connection while making sense in context is your answer.

Question 14

The athlete's decision to retire at her peak struck many fans as counterintuitive.

The word "counterintuitive" most nearly means

  1. financially insignificant
  2. painfully obvious
  3. technically illegal
  4. contrary to common sense (correct answer)
Explanation: When you encounter vocabulary-in-context questions, focus on breaking down word parts and using context clues to understand meaning. The word "counterintuitive" contains the prefix "counter-" meaning "against" or "opposite to," combined with "intuitive," which relates to what seems natural or obvious. The passage tells us that fans found the athlete's decision to retire "at her peak" to be counterintuitive. This context suggests something unexpected or puzzling—why would someone retire when they're performing at their best? Most people would intuitively expect an athlete to continue competing during peak performance, so retiring goes against this common expectation. Choice D, "contrary to common sense," perfectly captures this meaning. The decision defies what most people would naturally expect or consider logical. Choice A, "financially insignificant," is incorrect because the passage isn't discussing money or economic impact. The word "counterintuitive" has nothing to do with financial matters. Choice B, "painfully obvious," is wrong because it's actually the opposite of what "counterintuitive" means. Something counterintuitive is puzzling or unexpected, not obvious. Choice C, "technically illegal," is incorrect because "counterintuitive" doesn't relate to legality or rules. It's about expectations and logic, not laws. For vocabulary questions on the TACHS, always look for word parts (prefixes, roots, suffixes) and context clues. The prefix "counter-" appears in many words meaning "against" or "opposite," so recognizing this pattern will help you tackle similar questions confidently.

Question 15

Lydia refrained from commenting, sensing that any remark might be construed as criticism.

In the sentence, the word "construed" most nearly means

  1. ignored
  2. celebrated
  3. interpreted (correct answer)
  4. printed
Explanation: This question tests your ability to determine word meaning from context clues, a crucial skill for reading comprehension. When you encounter an unfamiliar word or need to choose the best meaning, look at the surrounding words and the overall situation to guide your thinking. In this passage, Lydia is being careful about speaking because she's worried that "any remark might be construed as criticism." The context tells us that Lydia fears her words could be understood or perceived in a negative way. The word "construed" refers to how someone might understand or make sense of her comments. Choice C, "interpreted," captures this meaning perfectly. To construe something means to interpret it or understand it in a particular way. Lydia is concerned that people might interpret her remarks as criticism, even if that wasn't her intention. Choice A, "ignored," doesn't fit because Lydia wouldn't refrain from speaking if she thought her comments would simply be overlooked. Choice B, "celebrated," makes no sense in this context—why would Lydia worry about her remarks being celebrated as criticism? Choice D, "printed," is completely unrelated to the situation and doesn't connect to the idea of how her words might be received or understood. When tackling vocabulary-in-context questions, always substitute each answer choice back into the original sentence to see which one maintains the logical flow and meaning. The correct choice should feel natural and preserve the author's intended message.

Question 16

The documentary highlights how pollutants can permeate even the most remote ecosystems.

As used in the sentence, "permeate" most nearly means

  1. bounce off
  2. spread throughout (correct answer)
  3. appear suddenly
  4. evaporate quickly
Explanation: When you encounter vocabulary-in-context questions, focus on how the word functions within the specific sentence and passage. Look for clues in the surrounding words that reveal the word's meaning. In this sentence, "permeate" describes what pollutants do to remote ecosystems. The key context clue is that pollutants can reach "even the most remote ecosystems" — places that are far away and isolated. This suggests the pollutants are getting into or throughout these areas in a thorough way. The word "permeate" means to spread throughout or penetrate completely, making choice B correct. Choice A, "bounce off," contradicts the entire meaning of the sentence. If pollutants bounced off ecosystems, they wouldn't be affecting them at all, which goes against the documentary's point about environmental impact. Choice C, "appear suddenly," focuses on timing rather than the thoroughness that "permeate" implies. While pollutants might appear suddenly, this doesn't capture how they spread through an ecosystem. Choice D, "evaporate quickly," suggests the pollutants disappear rapidly, which again contradicts the idea that they're affecting these remote places. For vocabulary questions on the TACHS, always read the word in context rather than relying on your general knowledge of word meanings. Look for surrounding words that act as clues — here, "remote ecosystems" suggests something that reaches far and penetrates thoroughly. Practice identifying these context clues, as they're often more reliable than trying to recall dictionary definitions.

Question 17

The musician's performance was so lackluster that even her most devoted fans seemed disappointed.

In the sentence, the word "lackluster" most nearly means

  1. carefully planned
  2. unexpectedly brief
  3. shockingly loud
  4. dull and uninspiring (correct answer)
Explanation: This question tests your ability to determine word meaning through context clues, a crucial reading comprehension skill. When you encounter an unfamiliar word, the surrounding text often provides hints about its meaning. Look at the context surrounding "lackluster." The sentence tells us that the musician's performance was so lackluster that "even her most devoted fans seemed disappointed." This is key information - if even the people who love her most were let down, the performance must have been particularly poor or disappointing in some way. The correct answer is D) dull and uninspiring. The word "lackluster" literally means "lacking luster" or brightness, so it describes something that fails to shine or impress. The context confirms this - a performance that disappoints devoted fans would indeed be dull and uninspiring. Looking at the wrong answers: A) carefully planned doesn't fit because planning has nothing to do with fan disappointment, and a well-planned performance could still please fans. B) unexpectedly brief also doesn't work - while fans might prefer a longer show, a brief performance wouldn't necessarily disappoint devoted followers. C) shockingly loud makes no sense in context, as volume alone wouldn't typically disappoint fans unless it was so excessive it ruined the experience. When tackling vocabulary-in-context questions, always use the surrounding sentences as your guide. Look for emotional cues (like "disappointed") and logical relationships that help you understand how the unknown word functions in the passage.

Question 18

The scientist's hypothesis was compelling, but it remained speculative until further data could be gathered.

In this context, the word "speculative" most nearly means

  1. wildly improbable
  2. not yet confirmed (correct answer)
  3. officially patented
  4. financially rewarding
Explanation: When you encounter vocabulary questions on the TACHS reading exam, context clues in the surrounding sentence are your best tool for determining meaning. Look for words or phrases that hint at the definition. In this passage, the key context clue is the contrast signal "but" which sets up an opposition between two ideas. The sentence tells us the hypothesis was "compelling" (convincing or attractive) BUT it remained "speculative" until more data could be gathered. This structure suggests that "speculative" describes something that lacks sufficient evidence or proof. The correct answer is B) "not yet confirmed." The phrase "until further data could be gathered" directly supports this meaning - the hypothesis needs more evidence before it can be verified or confirmed as true. Let's examine why the other choices don't work: A) "wildly improbable" is too extreme and negative. Nothing in the passage suggests the hypothesis is unlikely - in fact, it's described as compelling. C) "officially patented" relates to legal ownership of inventions, which has no connection to scientific hypotheses or the context provided. D) "financially rewarding" refers to monetary gain, which is completely unrelated to the scientific context of gathering data to support a hypothesis. Remember this strategy: when tackling vocabulary-in-context questions, always look for signal words like "but," "however," or "although" that indicate contrasts, and connecting phrases like "until" that show cause-and-effect relationships. These structural clues often point directly to the word's meaning within that specific context.

Question 19

Though Marcus claimed to have forgotten the incident, the slight tremor in his voice belied his calm expression.

What does the word "belied" mean as it is used in the sentence?

  1. supported with evidence
  2. revealed as false (correct answer)
  3. imitated exactly
  4. discussed openly
Explanation: When you encounter vocabulary questions on the TACHS reading exam, look for context clues that reveal the word's meaning through contrast or contradiction within the sentence. The key to understanding "belied" lies in recognizing the contrast being presented. Marcus claims he forgot the incident and appears calm on the surface, but his voice trembles. The sentence structure sets up an opposition: "Though Marcus claimed... his calm expression" versus "the slight tremor in his voice." The word "belied" describes the relationship between his trembling voice and his calm appearance. Since a tremor suggests nervousness or distress, it contradicts or exposes the falseness of his supposedly calm demeanor. Therefore, "belied" means "revealed as false" (B). Choice (A) "supported with evidence" is the opposite of what's happening—the tremor doesn't support his calm appearance; it contradicts it. Choice (C) "imitated exactly" doesn't fit because his voice isn't copying his expression; it's revealing something different. Choice (D) "discussed openly" makes no sense in this context, as the sentence isn't about verbal discussion but about contradictory physical signs. When tackling vocabulary questions, pay attention to signal words like "though," "but," "however," and "while" that indicate contrast. These often point to the relationship the unknown word describes. If you see opposing ideas in a sentence, the vocabulary word likely relates to that contradiction or conflict.

Question 20

The professor offered only a cursory glance at the report, missing its most critical flaw.

Here, "cursory" most nearly means

  1. angrily dismissive
  2. meticulously thorough
  3. brilliantly creative
  4. hasty and superficial (correct answer)
Explanation: Vocabulary questions like this test your ability to use context clues to determine word meaning. When you encounter an unfamiliar word, look at the surrounding sentence for hints about what the word must mean. The key context clue here is the phrase "missing its most critical flaw." This tells you that whatever type of glance the professor gave was insufficient—it wasn't thorough enough to catch an important problem. The word "only" also suggests limitation or inadequacy. These clues point to a quick, shallow examination rather than a careful one. "Cursory" means hasty and superficial, making D correct. A cursory glance is a brief, surface-level look that doesn't examine details carefully—exactly what would cause someone to miss critical flaws. Choice A (angrily dismissive) is wrong because nothing in the context suggests anger or dismissal—the professor did look at the report, just not carefully enough. Choice B (meticulously thorough) is the opposite of what the context suggests; if the glance were thorough, the professor wouldn't have missed the flaw. Choice C (brilliantly creative) doesn't fit because creativity has nothing to do with how someone examines a report, and again, this type of glance wouldn't miss important details. For TACHS vocabulary questions, always read the entire sentence and look for context clues that reveal the word's meaning. Words that describe actions often have clues in the consequences or results mentioned in the same sentence.
