Question 1: Main idea
Question 1 · Main idea · medium
In Grandmother’s version, the traveler asks a ferryman for help beside a flooded river. Her cousin sets the same story at a mountain pass and gives the warning to a mule driver. A younger teller moves it to a snowbound railway station. Each traveler first dismisses advice, encounters the predicted obstacle, and returns willing to listen. When the family compares the versions, they recognize the story before agreeing on any place names. Their disagreements concern the route and the guide, while the traveler’s change of mind remains familiar.
Which statement best summarizes the passage?
Worked answer and explanation
Answer: B. The story remains recognizable through a shared conflict and change in attitude even as its setting and characters vary.
The repeated dismissal, obstacle, and changed attitude provide continuity across the river, mountain, and railway settings. They recognize the story before agreeing on place names, which vary among versions. Each version includes dismissed advice, an obstacle, and a return with greater willingness to listen. The comparison centers on recognizable story versions, not proof of a real traveler’s route.
Question 2: Main idea
Question 2 · Main idea · easy
In a natural-history display, a robin’s nest rests beside a drawing of its layers. Dry grass and small twigs form much of the outer cup. A strip of paper is caught among them, while the label identifies mud beneath the softer inner lining. The guide asks the class to look at the different materials before counting any of them. What first appeared to be a simple bundle of grass turns out to contain several kinds of material.
What is the passage mainly about?
Worked answer and explanation
Answer: C. The variety of materials visible in a robin’s nest.
The description moves from an apparent grass bundle to several identified components, emphasizing material variety. No color preference or matching-color intention is established. The nest also contains twigs, paper, mud, and an inner lining. The class observes one displayed nest; the passage gives no universal count.
Question 3: Main idea
Question 3 · Main idea · hard
On Sela’s board, each knotted cord hangs beneath a small card. Two knots that look almost alike have cards describing different tasks; another pair, whose loops look quite different, shares a task heading. Sela once arranged the cords by the shapes they made, placing the neatest loops along the top. When preparing the board for a visitor who had asked about its uses, she moved those cords apart and set the two differently shaped examples together. She kept their individual names and descriptions on separate cards. The neat row at the top disappeared, although no knot had been retied or replaced.
Which statement best expresses the central point of the passage?
Worked answer and explanation
Answer: D. The board’s arrangement can emphasize practical relationships that are not evident from the knots’ appearance alone.
The unlike forms grouped under one task, the similar forms assigned different tasks, and Sela’s rearrangement together distinguish practical grouping from visual resemblance. The differently shaped examples are grouped by task, but their individual names remain on separate cards. The cords are rearranged without any knot being retied or replaced. The cards preserve names and descriptions while the new grouping deliberately separates the neatest visual row.
Question 4: Main idea
Question 4 · Main idea · hard
The chart records a pale object appearing darker at regular intervals during a tabletop experiment. In the original margin, the observer wrote that the object might be changing. A later sheet records the same intervals while a second, motionless object was placed beside it; both darkened together. The observer then checked the lamp and found its output falling at those intervals. On the chart, a dated note directs readers from the first suggestion to the lamp check. The measured times and the first suggestion remain legible. When the folder was cataloged, the later sheet was kept with the chart instead of being filed as an unrelated experiment.
Which statement best captures the passage’s main idea?
Worked answer and explanation
Answer: D. Preserving the linked records shows how further evidence changed an explanation without erasing the original observations.
The common timing, lamp check, dated cross-reference, and preservation of the earlier suggestion form a traceable change in interpretation while the observations remain available. The intervals are repeated and retained; the changed element is the explanation for the darkening. Legibility preserves the history of reasoning; the dated direction and lamp check supply additional evidence for the revised explanation, not equal support. The shared darkening and lamp check locate the cause in illumination, rather than establishing that the added object changed the first one.
Question 5: Main idea
Question 5 · Main idea · easy
The class compared twelve leaves collected beneath one tree after a windy night. Some were small and unmarked; others were larger, with torn edges or small holes. No single leaf displayed all the features present in the group. When the students chose a leaf for a drawing, their teacher asked them to keep the rest nearby for comparison. A drawing of one leaf could show that specimen well without representing every leaf they had found.
What is the main idea of the passage?
Worked answer and explanation
Answer: A. Leaves collected from one place can vary, so one specimen does not show every feature of the group.
The observed differences and the instruction to retain comparison specimens show the limits of treating one leaf as representative of the whole group. The passage describes differences in both size and damage. No such restriction is stated; one specimen can be represented well even if it is not representative of all the others. The windy night is background to the collection, not proof of the origin of every hole.
Question 6: Main idea
Question 6 · Main idea · easy
At Sela’s fruit stall, two trays hold the same kind of pear. One sign says “For today,” and the other says “For later in the week.” A customer points to the largest pear, but Sela first asks when it will be eaten. For tonight’s supper she chooses from the first tray; for a planned meal several days away she considers the second. Size is easy to see, but the stall’s arrangement directs attention to another part of the choice.
What is the main idea?
Worked answer and explanation
Answer: C. The seller helps customers match their purchase to when they intend to use it.
The tray labels and the seller’s question both connect selection with the intended day of eating. The seller asks about timing before selecting a tray, rather than choosing by size alone. Both trays contain the same kind of pear. The passage describes choosing for different intended days, not a minimum quantity.
Question 7: Main idea
Question 7 · Main idea · medium
Some older printed books were made from sheets folded into groups of leaves. In a particular copy on display, several upper folds remain joined: opening the cover does not make every printed surface accessible. A reader would have needed those joined folds opened to reach the enclosed pages. The margin explains that these are called unopened leaves. It also warns that rough outer edges alone are a different matter; an untrimmed book need not have joined pages. This copy makes the act of reaching the text part of its physical story.
Which statement best captures the main idea?
Worked answer and explanation
Answer: C. The way a book’s leaves were formed can affect access to its printed text.
The joined folds connect the book’s construction with the reader’s ability to reach particular pages; the distinction from untrimmed edges limits the claim. The passage distinguishes untrimmed edges from unopened leaves and makes no such universal claim. The joined folds in the displayed copy prevent access to some printed surfaces. The passage specifically describes enclosed printed pages, not blank replacements.
Question 8: Main idea

The picnic basket has the same outer size for every outing, but its inside need not stay divided in the same way. Two wooden panels lift from their slots. With both in place, several small containers remain separated. With one panel removed, a wide dish fits beside the remaining narrow compartments. For a single large parcel, both panels can be lifted out. The owner chooses the arrangement after seeing what needs to be carried.
What is the main idea?
Worked answer and explanation
Answer: A. Removable dividers let the same basket accommodate different loads.
The three internal arrangements show how moving the panels adapts the space within a fixed basket. A panel can be removed to make room for a wide dish. The passage says the outer size stays the same. The passage also describes arrangements for a wide dish or one large parcel.
Question 9: Main idea
Question 9 · Main idea · easy
A line of fence posts crosses the dune. In early photographs, dark bands near their bases are visible above the sand. Later pictures show those bands buried while the tops remain in the same positions. After another season, part of one band appears again. Wind can move sand into an area and later carry some away. The marked posts give observers fixed points beside a surface that is continually being reshaped.
What is the main idea?
Worked answer and explanation
Answer: A. Fixed markers make changes in the dune’s sand level easier to recognize.
The unchanged post positions provide a reference for the burial and reappearance of bands as sand moves. The post tops remain in the same positions; the surrounding sand level changes. Part of one band appears again in a later season. The passage describes one set of observations and gives no universal rate.
Question 10: Main idea
Question 10 · Main idea · hard
The novel’s first chapter follows a baker from the noon chimes until a delivery cart reaches her door. The next chapter begins with those same chimes, heard by the cart driver at the far end of the square. His account ends as he lifts the baker’s parcel. A third chapter returns again to noon, when a child watching from an upper window sees the cart enter the square but mistakes its destination. Readers reach the baker’s doorway twice, from different directions and with different expectations. The three narrators never share their thoughts with one another, and the third chapter ends before the parcel is carried inside.
Which statement best describes the passage’s main point about the novel’s arrangement?
Worked answer and explanation
Answer: B. It revisits overlapping events through separate viewpoints rather than moving steadily forward in time.
The repeated noon openings and the third chapter’s earlier endpoint establish temporal overlap, while the separate locations and mistaken destination establish differing perspectives. Each later chapter returns to noon, and the third ends before an event already reached in the earlier accounts. The child mistakes the destination, and the passage emphasizes different expectations. The narrators do not share their thoughts, and no correcting conversation occurs.
Question 11: Main idea
Question 11 · Main idea · medium
Two similar clocks hang in the entrance hall. Staff wind one each morning and compare it with the station clock so visitors can judge how long they have before a train. The other has its hands fixed at six seventeen, the moment commemorated by the display beneath it. A label explains that setting. During maintenance, staff correct the first clock if it has gained time, but restore the second to six seventeen if a hand has shifted. They do not judge the two clocks by the same test.
What is the main idea?
Worked answer and explanation
Answer: C. The clocks are maintained differently because they serve different purposes.
One clock measures passing time, while the other preserves a meaningful fixed setting; their maintenance follows those distinct roles. Only one tracks current time; the other marks a particular commemorated moment. Staff restore its chosen setting if a hand shifts, so it receives attention. The working clock specifically helps visitors judge their time before a train.
Question 12: Main idea
Question 12 · Main idea · medium
Nico drew a straight tail on the paper plan for a small wooden bird. As he shaped the block, a curved band in the wood’s grain appeared where that tail would be. He paused, set the plan beside the block, and redrew the tail to follow the visible curve. The head and wings remained as planned. When the bird was finished, the curve seemed part of its movement rather than a line that the maker had tried to conceal.
What is the main idea of the passage?
Worked answer and explanation
Answer: D. A feature revealed in the material led the maker to revise part of his design.
The sequence from exposed grain to a redrawn tail shows a design responding to the particular material. Only the tail changes; the head and wings remain as planned. The curve appears in the wood while Nico is shaping it and guides his revised drawing. The newly visible curved band prompts a change from the original straight tail.
