- According to Dr. Rodriguez's analysis, how many galaxies existed when the universe was less than 800 million years old were identified in the SMACS 0723 field of view?
Answer: The Webb data analysis identified 23 galaxies that existed when the universe was less than 800 million years old.
When you encounter reading comprehension questions about scientific data, focus on locating specific numerical information and matching it precisely to what the question asks.
The passage states that "Dr. Maria Rodriguez's analysis of the Webb data has identified 847 individual galaxies within the cluster's field of view, including 23 galaxies that existed when the universe was less than 800 million years old." The key word here is "including" - this tells you that 23 is a subset of the larger 847 total galaxies. The question specifically asks for galaxies that existed when the universe was less than 800 million years old, which corresponds exactly to these 23 galaxies.
Choice A correctly identifies 23 as the number of ancient galaxies from that specific time period. Choice B incorrectly uses 847, which represents the total number of galaxies identified in the field of view, not just the ancient ones. Choice C mistakenly uses 2,300, which refers to the total member galaxies in the entire cluster itself. Choice D uses 460, which comes from the cluster's mass measurement (460 trillion suns) and has nothing to do with galaxy count.
The wrong answers all use numbers that appear elsewhere in the passage but don't answer the specific question being asked. This is a common trap in reading comprehension - test makers include multiple numerical values to see if you can distinguish between different measurements and match the right data to the right question.
Always read the question twice and underline the specific detail being requested before scanning the passage for your answer.
- Where are the library's reference books currently kept during the renovation?
Answer: In the basement storage area during construction
When you encounter reading comprehension questions asking for specific details, you need to scan the passage for explicit information rather than making inferences.
The passage directly states that "all reference books were temporarily relocated to the basement storage area" during the renovation. This clear, factual statement tells you exactly where the books are currently located. The text also mentions that Ms. Hill posted signs to help patrons find these materials in their temporary location, confirming that choice A is correct.
Looking at the wrong answers: Choice B mentions a trailer behind the loading dock, but the passage never references a trailer or loading dock anywhere. Choice C describes rolling carts in the first-floor hallway, which isn't mentioned in the text at all. Choice D suggests the books are in Ms. Hill's office under supervision, but the passage only mentions that Ms. Hill posted signs—it doesn't say anything about her office or supervision.
Each incorrect answer introduces details that simply don't appear in the passage. These are classic distractors designed to test whether you're carefully reading the actual text or filling in gaps with assumptions.
For TACHS reading questions, always stick to what's explicitly stated in the passage. When a question asks "where," "when," or "what," scan for the exact words or phrases that answer that question directly. Don't overthink or add information that isn't there—the correct answer will always be supported by specific text from the passage.
- What percentage of the final grade does each of Professor Rowan's quizzes represent?
Answer: Five percent of the grade
When you encounter reading comprehension questions asking for specific factual details, your job is to locate the exact information stated in the passage without making inferences or assumptions.
The passage directly states that "Each quiz counts for only five percent of the final grade." This explicit statement gives you the answer immediately - no calculation or interpretation required.
Looking at the answer choices: A) Five percent is correct because it matches the passage's exact wording. B) Twenty percent might seem plausible if you mistakenly thought about multiple quizzes adding up, but the question asks what each individual quiz represents. C) Thirty-five percent has no basis in the passage and likely serves as a distractor. D) Fifty percent is clearly too high and contradicts the passage's emphasis that each quiz counts for "only" five percent.
The word "only" in the passage is a helpful signal - it indicates that five percent is a relatively small portion of the grade, which eliminates the larger percentages immediately.
For TACHS reading questions that ask "what," "when," "where," or "how much," always scan the passage for the specific detail being requested. These factual questions test your ability to locate and accurately identify information rather than analyze or interpret it. Don't overthink - if you see the exact information stated clearly in the passage, that's almost certainly your answer.
- According to Dr. Vasquez's research, what specific percentage of photosynthetic carbon can mature trees share with smaller trees during drought conditions?
Answer: Up to 15% of their photosynthetic carbon can be transferred to support neighboring trees during water stress periods.
When you encounter reading comprehension questions asking for specific data or statistics, your task is to locate the exact information in the passage without getting distracted by other numbers mentioned nearby.
The passage states that mature 'mother trees' can share "up to 15% of their photosynthetic carbon" with smaller trees during drought conditions. This information appears in the middle of the passage, specifically describing how these trees support neighbors within a 30-meter radius during water stress. Answer A correctly captures this precise figure and context.
Looking at the incorrect choices: Answer B uses 26%, which actually refers to the increase in seedling survival rates in areas with functional networks, not the carbon sharing percentage. Answer C mentions 40%, which describes how much faster forests with intact networks recover from disturbances, and incorrectly suggests this happens during "recovery periods" rather than drought. Answer D claims 90%, which refers to the percentage of fungal connections severed by logging equipment, not carbon transfer rates.
Each wrong answer contains a real statistic from the passage but applies it to the wrong context. This is a common trap in reading comprehension questions - test makers use actual data from the text to create plausible-sounding but incorrect options.
For TACHS reading questions with specific data, always match both the number and its context exactly. Don't just scan for the number mentioned in the question - make sure you're reading the complete sentence to understand what that statistic actually measures.
- How long will the new bicycle lane on River Avenue be?
Answer: Three miles in total length
This question tests your ability to locate and extract specific factual information directly stated in a reading passage. When you encounter questions asking for concrete details like measurements, dates, or quantities, the answer should be explicitly mentioned in the text.
Looking at the passage, the first sentence clearly states: "The city council approved funding for a new bicycle lane that will extend three miles along River Avenue." The word "extend" indicates the total length of the lane will be three miles. This directly supports answer choice A, which correctly identifies the bicycle lane as "three miles in total length."
Now let's examine why the other options are incorrect. Answer choice B claims the lane is "half a mile ending at the park entrance," but the passage mentions neither a half-mile length nor a park entrance. Answer choice C suggests "ten miles looping around downtown," but there's no mention of ten miles or any loop configuration in the text. Answer choice D describes "twenty miles stretching to the neighboring county," but again, neither twenty miles nor a neighboring county appears anywhere in the passage.
For reading comprehension questions asking about specific details, always scan the passage for exact information rather than making assumptions. The TACHS reading section frequently includes distractors that sound plausible but aren't supported by the text. Train yourself to find the precise wording in the passage that answers the question, and be wary of answer choices that introduce details not mentioned in the original text.
- According to the passage, what was the height of Temple IV when it was completed around 741 CE?
Answer: The structure reached a height of 65 meters, making it the tallest pre-Columbian building in the Americas.
When you encounter reading comprehension questions asking for specific details, your task is to locate the exact information in the passage and match it precisely with the answer choices.
The passage states: "The city's Temple IV, completed around 741 CE, stands 65 meters tall and was the tallest pre-Columbian structure in the Americas until the Spanish conquest." This sentence provides both pieces of information you need: the height (65 meters) and its historical significance (tallest pre-Columbian structure in the Americas).
Looking at the wrong answers: Choice B incorrectly states 575 meters, which confuses Temple IV's height with the total area of Tikal's urban complex (575 square kilometers). Choice C gives 61 meters instead of 65 meters, mixing up the temple's height with the number of structures discovered (over 61,000). Choice D claims 100 meters, which appears to confuse the temple's height with Tikal's estimated population (100,000 inhabitants).
Choice A correctly identifies both the 65-meter height and the historical distinction as the tallest pre-Columbian building in the Americas, making it the complete and accurate answer.
Strategy tip: In detail-oriented reading questions, watch out for number confusion—test makers often use other numerical data from the passage as distractors. Always trace back to the exact sentence containing your target information and double-check that all parts of the answer choice match the passage precisely.
- At what time does the train reach Willow Junction?
Answer: 7:15 p.m.
When you encounter time calculation problems on reading comprehension tests, focus on identifying the key time details and the relationship between them. Here, you need to track departure time, travel duration, and arrival time.
The passage states the train departs at 6:15 p.m. and takes "exactly one hour" to reach Willow Junction. To find the arrival time, add one hour to the departure time: 6:15 p.m. + 1 hour = 7:15 p.m.
Looking at the wrong answers: Choice B (6:20 p.m.) represents a common error where students might add only the 5-minute boarding time mentioned in the passage, forgetting that this boarding time happens before departure, not after. Choice C (8:45 p.m.) suggests confusion with the times given—perhaps misreading the departure time or incorrectly calculating the travel duration. Choice D (5:15 p.m.) is clearly impossible since it's before the departure time, indicating a student might have subtracted instead of added the travel time.
The correct answer is A (7:15 p.m.) because it accurately reflects adding the one-hour travel time to the 6:15 p.m. departure.
Strategy tip: In time problems, always identify what you're solving for first, then locate the relevant numbers while ignoring distractors. The 5-minute boarding time here is extra information that doesn't affect when the train arrives—only when passengers should board. Focus on departure time plus travel duration to find arrival time.
- For how long did Stefan set the baking timer?
Answer: Fifteen minutes
This question tests your ability to locate specific information directly stated in a passage. When you encounter detail questions like this, you need to scan the text carefully for the exact information being asked about.
The passage clearly states in the first sentence: "After setting the timer for fifteen minutes, Stefan placed the tray of oatmeal cookies into the preheated oven." This directly tells you that Stefan set his baking timer for fifteen minutes, making choice A correct.
Let's examine why the other options are wrong. Choice B (thirty minutes) is not mentioned anywhere in the passage and represents double the actual time Stefan set. Choice C (five minutes) is also not stated in the text and would be an unusually short baking time for cookies. Choice D (sixty minutes) appears nowhere in the passage and would likely result in the overbaked, hardened cookies that the recipe specifically warned against.
Notice that the passage provides additional context about Stefan's concern over overbaking, but this information serves as a distraction from the main detail being tested. The question asks for a straightforward fact that's explicitly stated in the opening sentence.
On reading comprehension tests, always look for questions that ask "according to the passage" or request specific details. These answers will be directly stated in the text, not inferred. Train yourself to locate key information quickly by scanning for numbers, names, and specific facts rather than getting caught up in descriptive details.
- Based on Dr. Murphy's analysis, what is the orbital period of the outermost planet TRAPPIST-1h?
Answer: TRAPPIST-1h has an orbital period of 18.77 days according to the comprehensive Kepler data analysis.
When you encounter reading comprehension questions asking for specific factual details, your task is to locate the exact information in the passage rather than making inferences or calculations.
The passage explicitly states: "The system's innermost planet, TRAPPIST-1b, completes an orbit in just 1.51 Earth days, while the outermost planet, TRAPPIST-1h, has an orbital period of 18.77 days." This directly answers the question about TRAPPIST-1h's orbital period, making choice A correct with its statement of "18.77 days according to the comprehensive Kepler data analysis."
Choice B incorrectly assigns the 1.51 Earth days orbital period to the outermost planet, when this actually describes TRAPPIST-1b, the innermost planet. This is a classic detail reversal trap. Choice C fabricates an orbital period of 2,550 days by misusing the star's surface temperature measurement (2,550 Kelvin) as an orbital period—a completely unrelated astronomical measurement. Choice D invents an orbital period of 66 days, possibly confusing the orbital period with the fact that TRAPPIST-1e receives 66% of Earth's stellar energy, again mixing unrelated data points.
On reading comprehension questions, always return to the passage for direct quotes rather than relying on memory. Watch for answer choices that mix up details from different parts of the text or incorrectly combine unrelated measurements—these are common traps designed to test whether you're reading carefully and tracking information accurately.
- What location are the wolves headed toward after crossing the meadow?
Answer: The river with deer tracks
Reading comprehension questions often test your ability to extract specific details directly stated in the passage. When asked about locations or directions, you need to trace the movement described in the text carefully.
The passage clearly maps out the wolves' journey: they emerge from the forest, cross the frost-covered meadow, and then head toward their next destination. The text explicitly states that Tala signals her companions "to continue toward the river, where deer tracks had been spotted the previous evening." This directly tells you their destination after crossing the meadow.
Choice A is correct because the passage explicitly mentions the wolves are heading "toward the river" where deer tracks were found. Choice B (rocky hilltop overlook) is never mentioned anywhere in the passage. Choice C (cave for shelter) also doesn't appear in the text - while wolves do use caves, this passage focuses on their hunting movement, not seeking shelter. Choice D (abandoned farmhouse) is completely absent from the passage, which describes a natural wilderness setting with forest, meadow, and river.
The key detail that confirms the answer is the phrase "where deer tracks had been spotted the previous evening" - this explains why the wolves are specifically heading to the river, making it clear this is their intended destination.
When answering detail questions, always look for information that's directly stated rather than making assumptions. Scan the passage for keywords from the question, and be wary of answer choices that introduce elements not mentioned in the text.
- Which student was NOT named as a recipient of a perfect attendance certificate?
Answer: Marcus
When you encounter reading comprehension questions that ask "which was NOT mentioned" or "which student was NOT named," you need to carefully track what information the passage actually provides versus what it doesn't mention.
The passage clearly states that Ms. Torres selected three specific students for perfect attendance certificates: Leila, Andre, and Priya. Each of these students attended every class without a single absence. This gives you a complete list of the certificate recipients.
Looking at the answer choices, you need to identify which name doesn't appear in this list. Choice A (Marcus) is correct because Marcus is never mentioned anywhere in the passage as receiving a certificate or even as a student in the class.
Choices B (Leila), C (Andre), and D (Priya) are all incorrect because each of these students is explicitly named in the passage as receiving a perfect attendance certificate. These are trap answers designed to test whether you read carefully and understood what the question was asking.
The key trap here is that three of the four answer choices come directly from the passage, which might make you think they're correct. However, the question asks for the exception—the one NOT mentioned. On reading comprehension questions like this, always double-check whether you're looking for what IS stated or what IS NOT stated in the passage. Circle or underline the word "NOT" when you see it to remind yourself what you're actually searching for.
- Based on Dr. Kim's surveys, what percentage of reefs in the northern section showed severe bleaching during the 2016-2017 event?
Answer: The northern section experienced 81% of surveyed reefs showing severe bleaching during the thermal stress event.
When you encounter reading comprehension questions that ask for specific data or statistics, your strategy should be to locate the exact information in the passage rather than relying on memory or making assumptions.
This question tests your ability to extract precise numerical data from a scientific text. The passage states: "The northern section experienced the most severe damage, with 81% of surveyed reefs showing severe bleaching compared to 33% in the central section and 1% in the southern section." This directly tells us that 81% of northern section reefs showed severe bleaching.
Choice A correctly identifies this 81% figure for the northern section. Choice B incorrectly states 33%, which is actually the percentage for the central section, not the northern section. Choice C gives 67%, which represents the mortality rate for fast-growing Acropora corals, not the percentage of northern reefs with severe bleaching. Choice D claims 45%, which refers to the percentage of affected reefs showing signs of regeneration 18 months later, not the initial bleaching percentage.
The wrong answers demonstrate a common trap in reading comprehension: mixing up different statistics from the same passage. The passage contains multiple percentages (81%, 33%, 1%, 67%, 12%, 45%), and test makers deliberately use these figures as distractors.
Always return to the passage to verify specific data points. Don't rely on your first reading, especially when dealing with dense scientific texts containing multiple statistics. Circle or underline key numbers as you read to avoid confusion.
- How many points did Jordan score in the first quarter?
Answer: Twelve points
This question tests your ability to locate and extract specific information directly stated in a reading passage. When you encounter questions asking for concrete details like numbers, dates, or names, your task is to scan the text for the exact information requested.
The passage clearly states: "Jordan scored twelve points in the first quarter alone." This direct statement gives you the answer without requiring any interpretation or calculation. The word "alone" emphasizes that this twelve-point total was achieved in just the first quarter, making the information even more explicit.
Looking at the wrong answers: Choice B (three points) appears nowhere in the passage and significantly understates Jordan's performance. Choice C (twenty-five points) is also not mentioned in the text and would be an unusually high first-quarter score that doesn't match the "twelve points" stated. Choice D (zero points) directly contradicts the passage, which emphasizes Jordan's strong early performance that "energized the team."
The correct answer is A (twelve points) because it matches the passage exactly.
For reading comprehension questions that ask for specific details, always look for direct statements in the text rather than making inferences. Scan for key words from the question—in this case, "Jordan," "points," and "first quarter"—to quickly locate the relevant sentence. Be wary of answer choices that seem reasonable but aren't actually supported by the passage text.
- According to the passage, what was Dr. Elena Morales's main purpose for traveling across the Atacama Desert in 1923?
Answer: To collect unstudied cactus specimens with potential healing properties
When you encounter reading comprehension questions asking about a character's main purpose or goal, look directly for explicit statements in the passage that reveal their primary motivation.
The passage clearly states that Dr. Elena Morales's "primary goal was to collect previously unstudied cactus specimens that, she believed, held medicinal properties." This direct statement makes choice A correct - she wanted to collect unstudied cactus specimens with potential healing properties. The phrase "medicinal properties" directly corresponds to "potential healing properties" in the answer choice.
Choice B is incorrect because the passage never mentions mapping uncharted desert sections or expedition planning for others. While she traveled across the desert, mapping wasn't her stated purpose. Choice C is wrong because there's no mention of testing equipment - the passage only notes that her team "braved" extreme temperatures, not that they were testing gear designed for those conditions. Choice D is incorrect because the passage doesn't mention searching for water sources for agriculture. While the team experienced water shortages, finding water wasn't their mission.
Notice how the wrong answers include plausible activities someone might do in a desert expedition, but they aren't supported by the text. On TACHS reading questions, always distinguish between what could logically happen versus what the passage actually states. Look for key phrases like "primary goal," "main purpose," or "set out to" that directly signal the author's intent, then match that language to the answer choices.
- Based on the passage, what was the primary factor that led to Petra's initial decline before the earthquake damage?
Answer: The Romans redirected trade routes through Palmyra after annexing the Nabataean Kingdom in 106 CE, undermining Petra's economic foundation.
When you encounter reading comprehension questions asking about cause and effect, focus on finding explicit connections the passage makes between events and their consequences. Look for key transitional phrases and chronological markers that show how one event led to another.
The passage clearly establishes a timeline where Petra thrived as a trading center because the Nabataeans "controlled lucrative incense routes between Arabia and the Mediterranean." The text then explicitly states that "The city began to decline after the Romans annexed the Nabataean Kingdom in 106 CE and redirected trade routes through Palmyra." This direct cause-and-effect relationship shows that Roman annexation and the subsequent rerouting of trade undermined Petra's economic foundation, making choice A correct.
Choice B is incorrect because the passage never mentions the Nabataeans losing control to competing Arabian tribes - it was the Romans who took control. Choice C misinterprets the water system information; the passage presents the sophisticated water management as evidence of engineering success, not failure, and gives no indication it was failing. Choice D reverses the chronology - nomadic tribes used Petra seasonally only after it was "largely abandoned" in the 7th century, not as a cause of its initial decline.
For TACHS reading questions about cause and effect, always trace the chronological sequence the passage provides. Look for words like "after," "began to," and "further" that signal the order of events. The correct answer will match both the timeline and the explicit causal relationships the author establishes, not assumptions you might make from background knowledge.
- How much did Charlene pay for her refurbished laptop?
Answer: $450
When you encounter reading comprehension questions that ask for specific factual information, your job is to locate the exact detail mentioned in the passage without making any calculations or inferences.
The passage directly states that Charlene "finally purchased the computer, paying $450 in cash without using a credit card." This sentence gives you the exact amount she paid for the laptop - no math required, no additional reasoning needed.
Looking at the wrong answers: Choice B ($250) might tempt you if you mistakenly think this represents half of some amount, since the passage mentions Charlene saved "half of every weekly paycheck." However, the passage doesn't tell you her weekly earnings, so you can't calculate anything from this information. Choice C ($650) and Choice D ($900) have no basis in the passage at all - they seem designed to catch students who might try to perform unnecessary calculations or make assumptions about her savings timeline.
The correct answer is A ($450) because it's explicitly stated in the text.
Study tip: On reading comprehension questions asking "how much" or other factual details, resist the urge to overcomplicate. Look for the direct statement in the passage first. The TACHS reading section often includes numerical distractors that might seem mathematically logical, but if the passage gives you a clear fact, trust what's written rather than trying to calculate or infer additional information.
- Based on the data provided, what was the total number of confirmed livestock deaths attributed to wolves between 1995 and 2020?
Answer: The Montana Fish, Wildlife & Parks department documented exactly 342 confirmed livestock deaths during this entire period.
When you encounter data-heavy reading passages, success depends on your ability to locate and extract specific numerical information accurately, without confusing different statistics presented in the text.
The passage states clearly: "The Montana Fish, Wildlife & Parks department documented that wolves were responsible for 342 confirmed livestock deaths during this period." This directly answers the question about confirmed livestock deaths between 1995 and 2020, making choice A correct.
Let's examine why the other options are wrong. Choice B misinterprets the $1.4 million figure—this represents compensation payments in dollars, not the number of livestock deaths. The passage mentions "compensation payments totaling $1.4 million for livestock losses," which is a monetary amount, not a death count. Choice C incorrectly associates the number 95 with livestock deaths, when the passage actually states this is the current wolf population: "the wolf population had grown to approximately 95 individuals." Choice D references 67 as confirmed fatalities, but the passage uses this number for increased wolverine sightings: "wolverine sightings increased by 67%."
For reading comprehension questions with multiple statistics, always match the exact wording of what's being asked. Here, you needed "confirmed livestock deaths," not compensation amounts, wolf populations, or wildlife sightings. Scan for key phrases that directly correspond to the question, and be careful not to mix up different numerical data points that appear close together in the passage.
- According to Dr. Lebreton's survey, what percentage of the total mass in the Great Pacific Garbage Patch consists of abandoned fishing gear?
Answer: Ghost nets and abandoned fishing gear comprise 46% of the total mass despite being less than 1% of individual pieces.
When you encounter reading comprehension questions asking for specific statistical data, your success depends on careful attention to exact numbers and what they represent. The passage provides multiple percentages, so you need to match the question's focus precisely.
The question asks specifically about the percentage of total mass consisting of abandoned fishing gear. Looking at the passage, you'll find this key sentence: "Surprisingly, abandoned fishing gear, known as 'ghost nets,' comprises 46% of the total mass despite representing less than 1% of the individual pieces counted." This directly states that abandoned fishing gear (ghost nets) makes up 46% of the total mass.
Choice A correctly captures both pieces of information from this sentence - the 46% mass figure and the less than 1% individual pieces detail. Choice B incorrectly states 34%, which actually refers to the percentage of plastic that "originated from fishing industry activities" - this is about source origin, not the mass percentage of abandoned gear specifically. Choice C uses 94%, which the passage identifies as the percentage of items that are microplastics, not fishing gear mass. Choice D claims 28%, but this figure represents debris "from land-based sources," not fishing equipment.
The trap here is that the passage contains several fishing-related statistics that could easily be confused. Always distinguish between percentages referring to mass versus individual pieces, and between abandoned fishing gear specifically versus broader fishing industry origins.
For TACHS reading questions with multiple data points, underline or highlight the specific statistic the question asks for, then match it exactly to avoid mixing up similar numbers.
- Based on Dr. Tanaka's expedition, what percentage of catalytic activity do the newly discovered enzymes maintain when exposed to temperatures 40°C higher than their natural environment?
Answer: The research revealed that these enzymes maintain 85% of their catalytic activity under elevated temperature conditions.
When you encounter reading comprehension questions that ask for specific numerical data, your task is to locate the exact information in the passage rather than making inferences or calculations.
The passage explicitly states: "The research revealed that these enzymes could potentially revolutionize industrial processes, as they maintain 85% of their catalytic activity even when exposed to temperatures 40°C higher than their natural environment." This directly answers the question about enzyme performance under elevated temperature conditions.
Choice A correctly captures this information, stating that the enzymes maintain 85% of their catalytic activity under the specified conditions. This matches the passage exactly.
Choice B claims 91% activity retention, but this number appears nowhere in the passage. The 91°C mentioned in the text refers to the temperature range around the vents, not enzyme activity levels.
Choice C suggests 80% activity retention, which is close to the correct figure but still inaccurate. This represents a common trap where test-makers use numbers similar to the correct answer.
Choice D states 60% activity persists, which is significantly different from the passage's data. The 60 meters mentioned in the text refers to the height of the Poseidon structure, not enzyme activity.
For TACHS reading questions involving specific data, always scan for exact numerical matches rather than trying to interpret or combine information. Underline key numbers as you read, and be wary of answer choices that use numbers from different parts of the passage in incorrect contexts.
- According to Dr. Walsh's report, what was the survival rate difference for adelie penguin chicks that fledge before adequate sea ice forms compared to those that fledge under normal ice conditions?
Answer: Chicks fledging before adequate sea ice forms have a 73% lower survival rate during their first year of life.
When tackling reading comprehension questions that ask for specific data from scientific passages, your first step is to locate the exact information rather than making inferences or calculations from related statistics.
The passage directly states: "chicks that fledge before adequate sea ice forms have a 73% lower survival rate in their first year." This matches answer choice A perfectly, making it correct. The passage presents this as a straightforward comparison between chicks that fledge early (before adequate ice) versus those that fledge under normal conditions.
Answer choice B incorrectly uses 56%, which actually represents the population decline at Cape Royds from 2018 to 2022 - a completely different statistic about breeding pairs, not chick survival rates. Answer choice C mistakenly uses 34%, which refers to the increased energy expenditure adult penguins face when traveling farther for food, not chick survival. Answer choice D incorrectly applies 21%, which describes the population growth at Cape Bird colony, again unrelated to chick survival rates.
The key trap here is that the passage contains multiple percentages (56%, 21%, 73%, 34%), and the incorrect answers deliberately mix these statistics from different contexts. Test writers often use this technique to see if you can distinguish between related but distinct pieces of data.
Strategy tip: In data-heavy reading passages, when asked for a specific statistic, scan for the exact keywords from the question. Here, look for "survival rate" and "chicks that fledge" rather than getting distracted by other numerical information. Always match the statistic to its precise context.
