Specific Details and Facts
The Mechanics of Scanning
Scanning is the targeted search for Anchor Words to locate Explicit Information without reading the entire passage.
Visual Matching: Focus your eyes on unique shapes like numbers, capital letters, or technical terms.
Keyword Selection: Identify nouns and verbs in the question that are unlikely to be paraphrased (dates, names, places).
Synonym Matching: Be prepared for the text to use a synonym of your anchor word — the passage may say 'inhabitants' where the question says 'residents'.
Scanning Order: Read the question first, lock onto 1–2 anchor words, then sweep the passage top-to-bottom. Do not re-read sentences that lack your anchors.
Verifying Information
The According to the Passage rule dictates that an answer must be verified directly by text evidence, not external knowledge.
Paraphrasing: Correct answers often restate facts using different vocabulary but the same logical Scope. 'Annual rainfall decreased' may appear as 'yearly precipitation declined'.
Literal Bounds: The passage's explicit statements override outside knowledge, even when 'common sense' suggests otherwise.
Scope Lock: The answer must match the same degree of generality as the text. If the passage says 'some researchers believe,' an option claiming 'all scientists agree' exceeds the stated scope.
Qualifier Traps
A Qualifier is a word that limits the scope of a statement (e.g., 'most,' 'some,' 'nearly,' 'often'), and misreading it is the most common source of wrong answers in detail questions.
Absolute vs. Hedged: 'Nearly all species' has a different scope than 'all species' — the qualifier 'nearly' restricts the claim to slightly less than the full set.
Extreme Qualifiers: 'Always,' 'never,' 'only,' and 'every' are absolute qualifiers. Passages rarely use absolutes, so their presence in an option is a strong signal to verify carefully.
Numerical Precision: 'Approximately 40%' ≠ 'exactly 40%.' 'More than 200' ≠ '200.' Match the qualifier exactly.
Temporal Qualifiers: 'Before the war' vs. 'during the war' vs. 'after the war' — a single preposition changes which detail is correct.
Fact vs. Opinion and Examples
Authors utilize Objective Facts and illustrative examples as evidence to support a central claim, and distinguishing facts from opinions is essential for detail questions.
Evidence Hierarchy: Specific details (dates, statistics, measurements) function as the foundation for broader arguments.
Subjective Opinion: Recognize when a detail reflects an author's view rather than a verifiable fact — signal words include 'arguably,' 'perhaps,' 'it seems.'
Purpose Identification: Ask why the author included a specific name or statistic; it usually illustrates a point, not stands alone.
Fact Signals: Dates, percentages, proper nouns, and citations mark objective facts. Adjectives like 'remarkable' or 'unfortunate' mark opinion.
Handling Negative Details
Negative Detail questions (NOT/EXCEPT) require an Elimination Strategy to find the one item missing from the text.
Checklist Method: Locate each option's claim in the text. Mark found items with a mental checkmark. The unmarked option is your answer.
Contradiction vs. Absence: The correct answer may be something the passage never mentions OR something it explicitly contradicts — both count as 'NOT mentioned/true.'
Sequence and Chronological Details
Some detail questions ask about the order or timing of events described in the passage, requiring careful attention to Temporal Markers like 'before,' 'after,' 'subsequently,' and 'prior to.'
Narrative Order ≠ Chronological Order: A passage may describe Event B first and then flash back to Event A. Read for logical sequence, not paragraph position.
Transition Signals: Words like 'meanwhile,' 'consequently,' 'thereafter,' and 'preceding' establish time relationships between details.
Multi-Step Processes: When a passage describes a procedure (e.g., 'First… then… finally'), the question may ask which step comes before or after another.

$\text{Rule: Match Anchor Words to Verified Text}$
Step 1
Anchor Word Identification
Read the question and identify the anchor words: 'decline', 'Mayan', 'reason'. These are the targets for our scan.
\text{Anchor} = \{\text{Mayan, Decline, Reason}\}
Step 2
Scanning the Text
Scan the passage specifically for 'Mayan' and 'decline' or synonyms like 'collapse'. Locate the specific sentence.
\text{Text:} \dots \text{soil analysis suggests a multi-decade drought depleted reservoirs}\dots
Step 3
Fact Extraction
Extract the core detail: 'multi-decade drought'. This is the literal cause mentioned in the environment-focused paragraph.
\text{Fact} = \text{Drought}
Step 4
Verification
Match this detail to the correct MCQ option. Ensure the choice doesn't add outside info like 'warfare' if the text only mentioned 'drought'.
\text{Option: (B) Sustained drought conditions}
Problem Statement
Determine which of four options is NOT mentioned as a benefit of solar energy according to a provided technical passage.

$\text{Checklist: A} \checkmark, \text{B} \checkmark, \text{C} \times, \text{D} \checkmark$
Step 1
Identify Question Type
Recognize the 'NOT' keyword. This means we are looking for the 'False' or 'Missing' statement.
\text{Goal} = \neg \text{Mentioned}
Step 2
Locate Benefits List
Scan for keywords like 'advantage', 'benefit', or 'positive'. The text lists: 1. Low maintenance, 2. Reduced bills, 3. Renewable source.
\text{List} = \{L.M., R.B., Ren.\}
Step 3
Option Comparison
Option A (Low maintenance) - Found. Option B (Renewable) - Found. Option C mentions 'lowest cost of installation,' but the text says 'high initial cost.'
\text{Option C} \neq \text{Text}
Step 4
Final Selection
Select Option C as the detail NOT mentioned or contradicted.
\text{Correct} = \text{Option C}
Problem Statement
A passage states: 'Nearly 70% of surveyed participants reported improved sleep after reducing screen time.' Which option correctly reflects this detail?
Qualifier IdentificationPrecision Matching
Strategic Toolkit
$\text{Rule: Qualifier in Text} \stackrel{?}{=} \text{Qualifier in Option}$
Step 1
Locate the Key Detail
Scan for the numerical detail. The passage says 'Nearly 70%' — lock onto both the number AND the qualifier 'nearly'.
\text{Detail} = \text{Nearly } 70\%
Step 2
Identify the Qualifier
The word 'nearly' limits the claim — it means slightly less than 70%, not exactly 70% or more than 70%.
\text{Nearly} \implies < 70\%
Step 3
Evaluate Trap Options
Option A: '70% reported improvement' (drops 'nearly' — too precise). Option B: 'Most participants reported improvement' (changes 'nearly 70%' to vague 'most'). Option C: 'Close to 70% of those surveyed saw sleep benefits after less screen time' (correct paraphrase). Option D: 'Over 70% improved' (reverses direction of qualifier).
\text{Only C preserves the qualifier's meaning}
Step 4
Final Selection
Select Option C — it paraphrases the detail while preserving the qualifier 'nearly' as 'close to,' the scope 'surveyed participants' as 'those surveyed,' and the cause-effect relationship.
\text{Correct} = \text{Option C}

In a passage discussing the history of penicillin, the author writes: 'Fleming's fortuitous observation of mold growth on an uncovered staphylococci culture — left unattended during his two-week holiday — would reshape modern medicine.' According to the passage, what specific circumstance led to the discovery?
Ans
A contamination of a bacterial culture while Fleming was away on holiday
Review
Tap to reveal
Identify the accidental setup
The key detail is that Fleming's culture was left unattended while he was away, so the discovery came from an unplanned contamination rather than an intentional experiment.
The mold grew on an uncovered culture left during his holiday.
Match the passage to the option
Option B restates that accidental contamination directly, while the other choices describe deliberate research or unrelated events.
Correct choice: B
2
A passage states: 'While most believe the Great Wall is a single continuous structure, it is actually a series of disconnected fortifications built across various dynasties, with the earliest sections dating to the 7th century BC.' Which detail is explicitly verified by the passage?
Ans
The earliest fortifications were built in the 7th century BC
Review

Option C is the only choice that repeats that verified detail without adding anything new.
Correct choice: C
3
A passage on the 1929 stock market crash lists three contributing factors: 'the prevalence of buying on margin by retail investors, overproduction of consumer goods creating an unsustainable glut, and a sharp decline in agricultural productivity across the Midwest.' Which factor is NOT mentioned in the passage?
Ans
A sudden increase in federal interest rates the week before the crash
Review
Tap to reveal
List the three stated causes
The passage mentions margin buying, overproduction, and falling agricultural productivity. Any correct answer must be outside that set.
Mentioned factors: margin buying, overproduction, declining farm output
Spot the absent item
Interest rates are not part of the passage at all, so Option B is the only choice that is not mentioned.
Correct choice: B

A passage states: 'Approximately 78% of the Earth's atmosphere consists of nitrogen, while oxygen accounts for nearly 21%, with the remaining fraction comprising argon, carbon dioxide, and trace gases.' According to the passage, what percentage of the atmosphere is oxygen?
Ans
Roughly 21%
Review
Tap to reveal
Preserve the qualifier
The passage does not say exactly 21%; it says nearly 21%, so the answer must keep the approximate wording.
Oxygen accounts for nearly 21%.
Choose the closest paraphrase
Option C keeps the same approximation without changing the meaning, making it the best match.
Correct choice: C
5
A passage on deep-sea ecosystems states: 'Giant Tube Worms, which can reach lengths of up to 2.4 meters, lack a digestive system entirely and instead rely on chemosynthetic bacteria housed within a specialized organ called the trophosome to convert hydrogen sulfide into usable energy.' Which detail about the Giant Tube Worm is verified by the passage?
Ans
They possess no digestive system and depend on internal bacteria for nutrition
Review
Tap to reveal
Use the biological function stated
The passage says Giant Tube Worms have no digestive system and depend on internal chemosynthetic bacteria for energy.
No digestive system; nutrition comes from bacteria
Match the paraphrase
Option C restates both parts of that claim accurately, so it is the verified detail.
Correct choice: C

A passage states: 'The Rosetta Stone, discovered by French soldiers in 1799 during Napoleon's Egyptian campaign, bore inscriptions in three scripts: hieroglyphic, Demotic, and Greek. It was not until 1822, however, that Jean-François Champollion successfully deciphered the hieroglyphic text.' How many years elapsed between the Stone's discovery and the decipherment of its hieroglyphs?
Ans
23 years
Review
Tap to reveal
Extract the two dates
The passage gives 1799 for discovery and 1822 for decipherment, so the time gap can be calculated directly.
$$1822 - 1799 = 23$$ years
Choose the exact difference
Since the gap is 23 years, the precise answer is not just 'about two decades' but the exact count given in Option A.
Correct choice: A
7
A passage states: 'While some historians argue that the printing press was Gutenberg's most significant contribution, recent scholarship suggests that his development of oil-based ink was equally revolutionary, as it adhered to metal type far more effectively than the water-based inks previously used.' According to the passage, what does recent scholarship emphasize about Gutenberg?
Ans
His oil-based ink was just as important as the printing press
Review
Tap to reveal
Track the emphasis in the passage
Recent scholarship does not reject the printing press, but it elevates oil-based ink to the same level of importance by calling it equally revolutionary.
Oil-based ink was as significant as the press
Match the scope exactly
Option B preserves the 'equally' relationship, while the other options either contradict or exaggerate it.
Correct choice: B
8
A passage states: 'The expedition, comprising 28 crew members and lasting 635 days, covered a total distance of approximately 56,000 kilometers before the vessel was ultimately crushed by pack ice at a latitude of 69°S.' According to the passage, how long did the expedition last?
Ans
635 days
Review

A passage about renewable energy states: 'Solar panels require minimal maintenance after installation but involve substantial upfront costs. Wind turbines, while efficient in coastal regions, generate significant noise pollution. Hydroelectric dams produce consistent output but can disrupt aquatic ecosystems.' Which statement is NOT supported by the passage?
Ans
Geothermal energy is the most cost-effective renewable source
Review
Tap to reveal
Check which sources are actually discussed
The passage covers solar, wind, and hydroelectric power. Geothermal energy never appears, so any geothermal claim is unsupported.
Discussed: solar, wind, hydroelectric
Select the unsupported statement
Option C is the only choice that introduces a completely new energy source, making it the unsupported statement.
Correct choice: C
