Find Information Stated Explicitly

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.

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.

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.

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.

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.

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.

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.

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

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.

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.

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.

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.
