What the Passages Look Like

Most Reading Comprehension items present a single paragraph, often 100 to 170 words, on a topic from science, technology, history, government, business, or military affairs, followed by one question. No outside knowledge is required or rewarded: every correct answer is grounded in the passage itself.

The passages are written in a compressed, formal style. Qualifiers such as most, often, may, usually, and in some cases carry real meaning, and the wrong answers are usually built by quietly removing or strengthening them.

How Wrong Answers Are Built

Overstatement

The passage says some or often; the choice says all or always.

Reversed relationship

The passage says A causes B; the choice says B causes A, or turns a correlation into a cause.

Out of scope

The choice introduces a comparison, cause, or recommendation the passage never mentions, even if it is true in real life.

Distorted detail

Real words from the passage rearranged into a claim it does not make.

Too narrow or too broad

For main-idea questions, a single detail or a topic larger than the paragraph.

The first part matches the passage but a second clause adds an unsupported claim.

On a best-supported question, the correct choice is often modest and plainly worded. A choice that sounds impressive or sweeping is usually the trap.

Passage: “Coral reefs occupy less than one percent of the ocean floor, yet they support roughly a quarter of known marine species. Many reef organisms depend on symbiotic algae that supply nutrients through photosynthesis. When water temperatures remain unusually high for several weeks, corals may expel these algae, a process called bleaching. Bleached corals are not dead, but they are weakened and, if conditions do not improve, may die.”

Which statement is best supported? A choice such as “Bleaching always kills the affected coral” overstates the passage, which says bleached corals may die. “Rising temperatures are the only threat to reefs” goes beyond it. “A prolonged period of high water temperature can threaten a coral's survival” is directly supported by the last two sentences and is the answer.

Answer from the passage only; outside knowledge is a trap. Watch qualifiers: may, some, often, usually. The best-supported choice is often the least dramatic one.

Read the Question, Then the Paragraph

Because each item usually has one paragraph and one question, read the question stem first so that you know whether to look for the main idea, a detail, an inference, or an unsupported statement. Then read the paragraph once, actively, noting its topic sentence, any contrast (however, but, although), and any cause-and-effect or conditional statements.

Identify the claim

Summarize the paragraph in one sentence before looking at the choices.

Decide what kind of statement the passage could support.

Test each choice

Point to the sentence that supports it; if you cannot, eliminate it.

Compare the survivors

Choose the one that requires the fewest assumptions.

Pacing on an Adaptive Test

You cannot skip or return, so commit to an answer on every item after eliminating what you can.

Spend the most care on the first several items; they set the difficulty level for the rest of the subtest. Budget roughly one to one and a half minutes per paragraph and keep moving; do not reread the whole paragraph

Use the scratch paper to jot a two- or three-word summary when a paragraph is dense.

Regular practice with dense expository writing, such as science journalism, government reports, professional journals, and naval history, builds the speed and precision the test rewards. After each paragraph, state its main point aloud and name one statement the author did not claim.

Read the stem first; read the paragraph once, actively. Every correct choice must be traceable to the text. Never leave an item unanswered.

Main Idea and Supporting Details

The main idea is the central point that the whole paragraph develops; it often appears in the first or last sentence. Supporting details are the facts, examples, and reasons that back it up. A correct main-idea choice covers the entire paragraph without adding anything new.

ORGANIZATIONAL PATTERNS Pattern Signal words because, therefore, consequently, as a result the difficulty, one remedy, to address this for example, studies show, this is demonstrated by

An inference is a statement that is not written in the passage but must be true, or is very strongly implied, given what is written. If a passage states that a new sonar system detects submarines at twice the range of the old one and that it has been installed only on destroyers, a valid inference is that destroyers now have a detection advantage over ships without the system. An invalid inference is that the old system will be retired, because the passage does not address it.

Inform or explain

Persuade or argue

Compare or evaluate

Weighing alternatives or strengths and weaknesses.

Many words have several meanings; the test asks for the one that fits the sentence. In “The commander's sanction was required before the operation could proceed,” sanction means approval, not penalty. Substitute each choice into the sentence and keep the one that preserves the meaning.

A fact can be verified (“The bridge opened with four lanes”); an opinion expresses a judgment (“The bridge is the city's finest structure”). In argument-based paragraphs, identify the claim, the evidence, and any unstated assumption that links them. A choice that depends on an assumption the author never made does not follow from the passage.

Main idea = the whole paragraph, no more and no less.

An inference must be true given the text, not merely possible. Choose word meanings from the sentence, not from memory.
