ISEE UPPER LEVEL • READING COMPREHENSION

Find Information Stated Explicitly

Master the skill of locating facts and details directly stated in a passage—no guessing required.

Why Explicit-Detail Questions Exist

Standardized reading tests have relied on explicit-detail questions for over a century. These questions check whether you can locate specific facts, dates, names, or descriptions that appear directly in the passage. Unlike inference questions, which require you to read between the lines, explicit-detail questions reward careful, precise reading. The ISEE Upper Level includes them on every passage because finding stated information is the foundation of all higher-order comprehension.

1900s
Early Comprehension Tests
Educators begin measuring reading skill by asking students to recall facts from short passages. The emphasis is on literal understanding.
1947
ETS Founded
The Educational Testing Service standardizes multiple-choice reading formats. Questions begin to distinguish between explicit recall and inference.
1960s
ERB & ISEE Launch
The Educational Records Bureau develops the ISEE for independent school admissions. Explicit-detail questions form a core question type across all levels.
Today
ISEE Upper Level Format
The ISEE Upper Level features six passages with six questions each. Explicit-detail questions—often called 'Supporting Ideas' questions—appear on virtually every passage.

Here is the central question this lesson addresses: when a question asks you about a specific fact, how do you find the right answer quickly and confidently, even under the time pressure of the ISEE? The answer lies in a repeatable strategy that turns every explicit-detail question into a scavenger hunt—with the answer always hiding in plain sight.

Core Principles of Finding Explicit Information

Explicit-detail questions are the most straightforward type on the ISEE Reading Comprehension section. However, 'straightforward' does not mean 'easy.' Test writers design wrong answer choices—called distractors—to closely resemble correct answers. Success depends on understanding a few non-negotiable principles.

1

The Answer Is in the Passage

Explicit-detail answers are always stated directly in the text. You should never need to guess, assume, or use outside knowledge. If you cannot point to the sentence that supports your choice, keep looking.
2

Read the Question First

Before scanning the passage, identify exactly what the question asks. Look for key nouns, dates, or names in the question stem—these are your search terms.
3

Locate, Then Match

Find the relevant sentence or sentences in the passage. Read them carefully. Then compare each answer choice to the text. The correct choice will paraphrase—not copy word-for-word—what the passage says.
4

Beware of Paraphrase Traps

Distractors often use vocabulary from the passage but change the meaning. A choice can quote a real phrase from the text and still be wrong if it distorts the original idea.
5

Eliminate with Evidence

Cross out any choice that contradicts the passage, goes beyond what is stated, or addresses a different part of the text. On the ISEE, there is no penalty for guessing, so always select an answer.

The Locate-and-Match Process

The diagram below illustrates the four-step process you should follow every time you encounter an explicit-detail question on the ISEE. This visual workflow turns a potentially stressful task into a simple, repeatable procedure.

Follow this four-step workflow for every explicit-detail question: identify key words, scan, read carefully, then match. Notice that the final step involves elimination—you are not just picking the best-sounding answer; you are ruling out choices that do not align with the passage.

Step 1 is where most students can save time. Instead of re-reading the entire passage, you extract key words from the question—proper nouns, dates, technical terms, or unique phrases—and use them as search terms in Step 2. Once you locate the relevant area of the passage, Step 3 requires you to read not just the target sentence but the sentences immediately before and after it, because the answer sometimes spans two sentences. Step 4 is the moment of truth: compare each answer choice against the passage and eliminate anything unsupported.

How Explicit-Detail Questions Work on the ISEE

On the ISEE Upper Level, explicit-detail questions are classified under the broader category of Supporting Ideas questions. They typically use question stems that signal you need to find a fact rather than make a judgment. Recognizing these signal phrases is essential for applying the right strategy.

Common Question Stems

  • "According to the passage, …"
  • "The author states that …"
  • "Which of the following is mentioned in the passage?"
  • "The passage indicates that …"
  • "Based on the passage, [specific noun] is described as …"
  • "In lines X–Y, the author mentions … in order to …" (when asking what, not why)

When you see phrases like "according to the passage" or "the author states," the test is telling you directly: do not go beyond the text. Your answer must be something the passage literally says, even if it is rephrased. This is different from inference questions, which use stems like "it can be inferred" or "the author would most likely agree." Making this distinction quickly will save you valuable time.

The Anatomy of a Distractor

Test writers craft wrong answers using four common techniques. A too broad distractor generalizes beyond the passage's specific claim. A too narrow distractor picks only a small part of the answer and misses the rest. A misquote uses real words from the passage but rearranges or alters them to change the meaning. Finally, an out-of-scope distractor introduces information that sounds plausible but never actually appears in the text. Understanding these patterns helps you eliminate wrong answers confidently.

Classifying and Defeating Distractors

The diagram below categorizes the four main distractor types and shows how each one deviates from the passage's actual content. Learning to recognize these patterns will sharpen your elimination skills and increase your accuracy.

This diagram shows how the four distractor types deviate from the passage's actual fact. The correct answer accurately paraphrases the passage—never adding, removing, or distorting information.
Four distractor types and how to defeat them
Distractor TypeWhat It DoesHow to Spot It
Too BroadExpands a specific detail into a sweeping generalizationLook for words like "all," "always," "every," or "never" that the passage did not use
Too NarrowFocuses on only one part of the answer, ignoring the restCheck whether the answer choice captures the full idea of the relevant sentence
MisquoteBorrows real words from the passage but changes relationships or meaningsRe-read the original sentence word by word; check cause-effect or comparison relationships
Out of ScopeIntroduces plausible information that the passage never mentionsAsk: "Where in the passage does it say this?" If you cannot find it, eliminate the choice

Worked Example: Locating Explicit Information

Let's walk through a complete example. Read the following short passage and question, then follow along as we apply the four-step workflow.

SAMPLE PASSAGE
QUESTION
1
Step 1 — Identify Key Words in the QuestionThe question asks: "According to the passage, why do some Arctic terns take a zigzag route?" The key search terms are zigzag route and Arctic terns. The phrase "according to the passage" confirms this is an explicit-detail question.
2
Step 2 — Scan the PassageScanning for "zigzag route," we find it in the third sentence: "Scientists discovered in 2010 that some individual terns take a zigzag route over the Atlantic Ocean rather than a direct path."
3
Step 3 — Read the Surrounding SentencesThe very next sentence provides the reason: "Researchers believe the birds follow this indirect route because it allows them to exploit prevailing wind patterns, ultimately conserving energy despite the greater distance." This sentence directly answers the 'why' in the question.
4
Step 4 — Match and EliminateChoice (A) mentions avoiding predators—never stated in the passage (out of scope). Choice (C) mentions searching for food—also never stated (out of scope). Choice (D) mentions magnetic interference—entirely fabricated (out of scope). Choice (B) says "following prevailing wind patterns to conserve energy," which directly paraphrases the passage's final sentence.
Correct Answer: (B)

Strategies, Strengths, and Common Pitfalls

Explicit-detail questions are among the most reliable opportunities to earn points on the ISEE because the answer is always in the passage. However, students frequently lose points on these questions due to predictable mistakes. Understanding both the strengths and pitfalls of this question type will help you approach them with maximum confidence.

Strengths vs. pitfalls for explicit-detail questions
Strengths (Why These Are Scoreable)Common Pitfalls (Why Students Miss Them)
The answer is always stated in the text—no interpretation neededRushing and choosing an answer from memory instead of re-checking the passage
You can verify your choice by pointing to a specific sentenceBeing tricked by a misquote that uses real passage vocabulary in a twisted way
Process of elimination is highly effective—distractors are provably wrongConfusing an explicit-detail question with an inference question and over-thinking
Key-word scanning makes relocating information fastReading only the target sentence and missing context in surrounding sentences

Explicit Detail vs. Other Question Types

As you grow more comfortable with explicit-detail questions, it is important to understand how they relate to the other question types on the ISEE. The table below contrasts explicit-detail questions with inference and main idea questions—two types that students sometimes confuse with explicit detail.

Comparing three core ISEE question types
FeatureExplicit DetailInferenceMain Idea
Signal words"According to the passage," "the author states""It can be inferred," "the author implies""The main idea of the passage is," "primarily about"
Where is the answer?Stated directly in a specific sentenceImplied by evidence; requires a logical step beyond the textCaptured by the overall message of the entire passage
StrategyLocate the fact, match the paraphraseIdentify evidence, draw a reasonable conclusionConsider the passage as a whole, not just one detail
Common mistakeAdding personal interpretation when only recall is neededChoosing an answer that is directly stated (too literal)Selecting a detail from one paragraph rather than the whole-passage theme

Mastering explicit-detail questions builds a strong foundation for tackling inference and main idea questions. Once you can reliably find what the passage says, you are better positioned to determine what it implies and what overarching message it conveys. Think of explicit detail as Level 1 comprehension—and the other question types as Level 2 and Level 3 built on top of it.

Reading Passage

In 1928, Alexander Fleming noticed that mold in a contaminated petri dish had killed nearby bacteria while more distant bacteria survived. He identified the mold as Penicillium and named the antibacterial substance penicillin.

Penicillin became a practical medicine in 1940 when Howard Florey and Ernst Boris Chain developed methods to purify and mass-produce it. During World War II, penicillin saved many soldiers from potentially fatal infections.

In 1945, Fleming, Florey, and Chain received the Nobel Prize. Fleming also warned that overuse of antibiotics could lead to resistant bacterial strains.
