What you will learn

  • State the subject and the author’s point in one sentence.
  • Distinguish an important detail from the main idea.

A method you can repeat

  1. Ask what the passage is mostly about: this gives you the subject.
  2. Ask what the author explains about that subject: this gives you the point.
  3. Check your summary against every sentence. Reject answers that are too narrow, too broad, or unsupported.

Worked example: follow the evidence

Read: The repair shop placed outline labels above its tool racks. Workers could now see where each tool belonged, and new employees needed less help finding equipment. At closing time, empty outlines also made missing tools easy to spot.

Which statement best expresses the main idea?

Supported answer: Outline labels help workers locate, return, and account for tools.

Why it fits: Finding equipment and spotting missing tools are both benefits of the same labeling system. A useful summary must cover both.

Tempting wrong answer: New employees need help finding equipment.

Why it fails: This is connected to one sentence, but it leaves out returning tools and spotting missing ones. A related detail is not necessarily the main idea.

Before each answer: Before choosing, say: “This passage is about ___, and its main point is ___.”

Question 1: Main idea

Question 1 · Main idea · hard

The history’s chapters follow the town from its first quay to its later railway station. A reader turning the pages in order encounters lamp makers briefly in three different periods. Another reader, investigating lamps, begins instead with the index. Its entry separates workshop locations, designs and repairs, directing that reader to several sections rather than to one continuous account. During revision, the author kept the chronological chapters and expanded these subentries. She rejected a proposed index that merely repeated the chapter titles. The index supplies page locations, not definitions or new essays; the surrounding pages still explain how each example belongs to its period.

Which statement best captures the main idea?

Choose an answer for question 1
Worked answer and explanation

Answer: D. The book supports both following a continuous history and tracing a particular subject across that history.

The retained chronology serves sequential reading, while detailed subentries connect scattered examples for a targeted inquiry without replacing their context. The chapters are retained, and the index supplies page locations rather than new narratives. The passage specifically says the index does not supply definitions; its subentries point to relevant discussions. The passage explains how the examples belong to their periods, not that the chronological account is incoherent.

Question 2: Main idea

Question 2 · Main idea · medium

At the reading group, Dev asked everyone to turn to page ninety-four. In Rosa’s larger-print copy, that page was still several scenes behind his. Dev then quoted the first few words of the innkeeper’s warning and described the door closing just before it. Rosa found the same wording on page one hundred thirty-seven. Another reader used those details to find it in a pocket edition. The copies arranged the words differently on their pages, but the warning and the event around it gave the group a shared place to begin.

What is the main idea?

Choose an answer for question 2
Worked answer and explanation

Answer: A. Details from the text can identify a common passage when page numbers differ across editions.

The failed page-number reference is replaced by a distinctive line and event that remain recognizable across the different layouts. Rosa finds the same wording and scene, despite a different page number. The passage makes no connection between page number and textual accuracy. The readers locate the shared scene by its words and surrounding event in their existing copies.

Question 3: Main idea

Question 3 · Main idea · medium

Rosa had to remember a candle, a ribbon, a spoon, and a small bell. Repeating the four names soon left her unsure which one she had missed. She imagined a candle wearing a ribbon, the ribbon tied to a spoon, and the spoon striking the bell. At the shop, she recalled that unlikely scene from its beginning and named each object as it appeared. The story had no practical meaning, but in this instance its connections gave her a path through the list.

What is the main idea?

Choose an answer for question 3
Worked answer and explanation

Answer: D. Linking separate items in an imagined sequence helped Rosa recall them.

The imagined links supply an order Rosa can follow to retrieve the individual items. Their connection is an invented, unlikely scene, not an ordinary shared use. She recalls and names the same four objects. It reports one person’s experience in one instance, not a universal result.

Question 4: Main idea

Question 4 · Main idea · easy

The charcoal portrait contains no continuous outline around the face. A dark mark beneath the cheek suggests its turn, and another beside the nose gives that feature depth. Between those marks, much of the paper remains bare. Viewers nevertheless recognize a complete face. The artist has not drawn every edge; a few carefully placed shadows lead the eye to supply connections across the untouched areas.

What is the main idea?

Choose an answer for question 4
Worked answer and explanation

Answer: C. Selected marks can suggest a complete form without outlining every part.

The recognized face emerges from a few shadow marks and the viewer’s connections between them. Viewers recognize the face despite the absence of a continuous outline. No hidden lines are mentioned; the eye supplies connections between the visible marks. The marks are described as giving the face form and depth, not covering errors.

Question 5: Main idea

Question 5 · Main idea · easy

At the gathering, clean cups stood on a tray at one end of the table. At the other end, a basin marked USED CUPS held the cups that guests had finished with. Nola asked people to place a used cup in the basin instead of setting it beside the clean stack. New arrivals could then choose from the tray without wondering whether a cup left loose on the table had already been used.

What is the main idea of the passage?

Choose an answer for question 5
Worked answer and explanation

Answer: B. Separate places for clean and used cups make their status easier to recognize.

The tray and labeled basin distinguish cups available for use from cups already used. The passage describes clean cups supplied on a tray, not a requirement to bring them. It is labeled for used cups; clean cups remain on the separate tray. The stated distinction concerns use, and no decorative comparison is described.

Question 6: Main idea

Question 6 · Main idea · medium

Before bringing an umbrella from the lost-property cupboard, the clerk asked its claimant to describe it. Two umbrellas matched the stated color and curved handle, but only one had the small stitched patch the visitor described on the inner fabric. The clerk found that feature before setting the umbrella on the counter. Later, another visitor described a notebook inside a zipped pocket of a bag that had not yet been shown. In each case, the clerk wrote down the distinguishing information before checking the stored object.

What is the main idea of the passage?

Choose an answer for question 6
Worked answer and explanation

Answer: C. Details supplied before an object is shown help the clerk distinguish the claimed item from similar belongings.

Both examples use independently supplied, specific details to help match a claim to a stored belonging. Two umbrellas share the stated color and handle, so the more specific patch matters. The descriptions are recorded before the objects are shown. That detail belongs to the bag in the second example, not all objects.

Question 7: Main idea

Question 7 · Main idea · medium

At rehearsal in the stone hall, the reader began each new line while the last words of the previous one were still audible around her. From the back row, her partner heard the sounds overlap. For the evening reading, she left a longer silence between lines and waited for that lingering sound to fade. She kept every word and retained the original order. Her marked copy recorded pauses chosen for that hall, rather than a revised version of the poem’s text.

What is the main idea of the passage?

Choose an answer for question 7
Worked answer and explanation

Answer: A. The reader adjusts the poem’s delivery to the way sound behaves in the performance space.

The repeated sound in the hall prompts a timing adjustment while the verbal text remains unchanged. Every word and its order are retained; the change concerns timing. The pauses are chosen in response to the particular hall’s lingering sound. The observed overlap leads to longer silences, not the removal of pauses.

Question 8: Main idea

Question 8 · Main idea · medium

The retired deckhand built his model of the ship without a plan, relying on what he remembered. The winches and working lines were carefully placed, and he could explain how each had been used during a busy departure. Below the removable deck, however, several rooms were left blank. He had seldom entered those spaces and did not try to invent their furniture. The model was most detailed where his own work had carried him repeatedly, and its gaps followed the boundaries of that experience.

What is the main idea of the passage?

Choose an answer for question 8
Worked answer and explanation

Answer: D. The maker’s firsthand familiarity shapes both the model’s detail and its omissions.

The contrast between well-known deck equipment and unfamiliar blank rooms connects representation to the maker’s experience. Several rooms are left blank, while familiar working equipment is carefully represented. He specifically avoids inventing the furniture in spaces he barely knew. The lines are carefully placed, and he can explain their use.

After this set: choose one missed answer and name the exact mistake: an added assumption, a lost condition, a detail mistaken for the main idea, or another mismatch with the text. Explain the correction in your own words before trying the next set.
