The companion set to Workshop 3. Twelve real-style questions on main idea and inference, played one at a time. Predict the answer before you look, then check yourself against the four traps.
Before you read the choices, answer the question in your own words. Then find the choice that matches your prediction. Three of the four choices are built to fool you, usually in one of these ways:
Word Echo. Repeats words from the passage but misses the point.
Opposite Direction. Says the reverse of what the text says.
Too Extreme. Overreaches with "all," "only," or "never."
True but Irrelevant. A real detail, but not what the question asks.
Plausible but Unsupported. Sounds reasonable, but the passage never actually says it.
Question 1 of 12
Main IdeaWarm-up
Poets who compose in sign languages work with tools that spoken-language poets do not have. Deaf poet Rowan Adeyemi, for example, uses the space around her body as part of her poems: a sign placed high and far away can suggest a distant memory, while one made close to her chest can suggest something private. She also repeats hand shapes across several signs, creating a visual pattern that works much like rhyme does in spoken verse.
Which choice best states the main idea of the text?
The takeaway: The first sentence states the main idea (sign-language poets have special tools), and the rest gives Adeyemi's use of space and repeated hand shapes as examples. Choice A captures that point.
InferenceWarm-up
Embroidered samplers, pieces of cloth on which young people practiced stitching, were often signed but rarely dated. One sampler in a small Welsh museum shows a verse and a picture of a ship labeled with the name Morwennol. Curator Rhys Pritchard found shipyard records showing that the Morwennol was first launched in 1831 and that no earlier ship carried that name. It can therefore be concluded that the sampler ______
Which choice most logically completes the text?
The takeaway: The sampler shows a ship named Morwennol, and the records show no ship had that name until 1831. So the sampler must have been made in 1831 or later; this is the only conclusion the dating evidence forces.
Main IdeaWarm-up
Salt marshes are coastal wetlands covered with grasses and flooded by the tide twice a day. As the tide rises, the water carries fine particles of mud and sand. When the water flows through the dense grass stems, it slows down and drops these particles, which build up on the marsh surface. Ecologist Darnell Whitfield has measured this buildup and found that, in healthy marshes, it can raise the ground level fast enough to keep the marsh from being drowned as sea levels slowly rise.
Which choice best states the main idea of the text?
The takeaway: The passage explains how marsh grasses slow the tide so particles settle, and it ends with Whitfield's finding that this buildup can keep healthy marshes above rising seas. Choice B states that main idea.
InferenceWarm-up
Researcher Hana Kobayashi observed visitors in an art museum where some paintings had benches placed in front of them and others did not. Visitors spent an average of 50 seconds in front of paintings with benches but only about 20 seconds in front of similar paintings without benches. When the museum moved the benches to different paintings, the longer viewing times moved with them. These findings suggest that ______
Which choice most logically completes the text?
The takeaway: The key detail is that the longer viewing times moved along with the benches. That rules out the idea that visitors simply preferred certain paintings and supports the conclusion that benches lead visitors to look longer.
Main IdeaWarm-up
Most public libraries lend books, but some have expanded what they offer. The public library in the town of Wrenfield now lends power drills, sewing machines, telescopes, and even cake pans. Librarian Oksana Delacroix-Mwangi explains that many residents need such items only once or twice a year and would rather not buy them. Since the collection opened, she reports, the tools have been borrowed thousands of times, and many borrowers are people who had rarely visited the library before.
Which choice best summarizes the text?
The takeaway: The passage describes Wrenfield's new lending collection, why residents want it, and its results: heavy use and new visitors. Choice C summarizes the whole passage.
InferenceWarm-up
Limpets are small, cone-shelled animals that cling to rocks along the seashore. Marine biologist Chidi Okafor measured how much force was needed to pull limpets off rocks and found that the force was much greater on days with strong waves than on calm days. He concludes that limpets grip the rock more tightly when waves are rough. Based on Okafor's conclusion, a limpet on a rock during a storm with strong waves would most likely ______
Which choice most logically completes the text?
The takeaway: Okafor's measurements and conclusion show that limpets hold on more tightly in rough water. A limpet in a storm with strong waves should therefore be harder to pull off than the same limpet on a calm day.
Main IdeaWarm-up
Psychologist Ines Kowalczyk-Adebayo asked two groups of volunteers to memorize the same list of twenty grocery items. The first group simply studied the list as written. The second group was told to sort the items into categories, such as fruits, dairy, and cleaning supplies, before studying them. When tested an hour later, the second group recalled far more items, which led Kowalczyk-Adebayo to conclude that organizing information into categories makes it easier to remember.
Which choice best states the main idea of the text?
The takeaway: The passage describes an experiment and its result: the group that sorted items into categories remembered more. Choice D states that main finding.
InferenceWarm-up
Many potters use glazes that contain copper. Ceramic chemist Adebayo Ogun explains that when a copper glaze is fired in a kiln with plenty of oxygen, it turns green, but when the kiln's oxygen supply is limited, the same glaze turns deep red. A potter opened a kiln and found that a bowl coated in a copper glaze had come out bright green. This result indicates that the bowl was most likely fired ______
Which choice most logically completes the text?
The takeaway: Ogun links a green copper glaze to firing with plenty of oxygen and a red one to limited oxygen. Since the bowl came out bright green, the kiln most likely had plenty of oxygen.
Main IdeaWarm-up
In the early days of cinema, films had no recorded sound, so many theaters hired pianists to play during screenings. These musicians rarely received printed scores. Instead, pianist Mabel Okafor, who played in a Chicago theater in the 1910s, described watching each new film once in the morning and then improvising music that matched its scenes during the evening shows. She noted that a chase scene called for fast, rising passages, while a farewell called for slow, quiet chords.
According to the text, how did Mabel Okafor prepare to play for a new film?
The takeaway: The text directly states that Okafor watched 'each new film once in the morning' and then improvised music 'during the evening shows.' Choice A restates that detail.
InferenceWarm-up
Until 1870, the town council of a small farming community in the American Midwest kept its meeting records only in English. That year, after dozens of German-speaking families settled in the town, the council began recording each meeting in both English and German. Historian Grace Oyelaran notes that at the same time, the council also began posting notices of upcoming meetings in both languages. These changes suggest that the council ______
Which choice most logically completes the text?
The takeaway: Both changes, German records and German meeting notices, began just after German-speaking families settled in the town. Together they suggest the council wanted these new residents to be able to understand and follow its activities.
Main IdeaWarm-up
For centuries, wool dyers relied on plants such as madder and indigo for color. Textile artist Siobhan Nakashima has been experimenting with a different source: wild mushrooms. She simmers dried mushrooms in water to make a dye bath, then soaks wool in it for several hours. According to Nakashima, some species that look plain brown on the forest floor produce surprisingly bright colors, including rose, gold, and even blue-green.
According to the text, what has Nakashima found about some mushroom species?
The takeaway: The text states that, according to Nakashima, some species 'that look plain brown on the forest floor produce surprisingly bright colors.' Choice B restates that finding.
InferenceWarm-up
Linguist Salote Havili compared the vocabularies of two neighboring Pacific island communities whose languages are only distantly related. She found that the communities use nearly identical words for fishing nets, hooks, and canoe parts but very different words for farming tools and crops. Historical accounts show that fishers from both islands often worked the same waters and traded equipment, while farmers rarely traveled between the islands. This evidence suggests that ______
Which choice most logically completes the text?
The takeaway: The shared vocabulary is limited to fishing, and the historical accounts show that fishers, not farmers, had regular contact across the islands. This match between who met and which words are shared suggests the fishing words spread through the fishers' contact.
