1. Origami Development Question: Though its early history is not fully known, origami, the art of folding objects out of paper without cutting, pasting, or decorating, seems that it had developed from the older art of folding cloth. Options: a. developing, it seems, out of b. seems it would have been developed out of c. seems to have developed from d. NO CHANGE Correct Answer: c. seems to have developed from Rationale: The phrase "seems to have developed from" correctly uses the present perfect infinitive ("to have developed") to indicate an action that occurred in the past relative to the present. The original sentence incorrectly uses "had developed," which creates a tense inconsistency.
2. Ethan’s Valuation of Mattie Question: The description in the first paragraph indicates that what Ethan values most about Mattie is her... Options: a. fitness for farm labor b. vivacious youth c. freedom from worry d. receptive nature
Correct Answer: d. receptive nature Rationale: The text highlights Mattie’s ability to harmonize with Ethan’s moods and desires, emphasizing her attentiveness and adaptability, which align with a "receptive nature."
3. Textual Evidence for Ethan/Mattie Question: Which choice from paragraph one provides the best evidence for the answer to the previous question? Options: a. Lines beginning "But it...hearth" b. Lines beginning "Mattie...farm" c. Lines beginning "She had...will" d. Lines beginning "He had...anyhow" Correct Answer: c. Lines beginning "She had...will" Rationale: These lines likely describe Mattie’s willingness to align with Ethan’s preferences, directly supporting the idea of her "receptive nature."
4. Rectangle and Squares Perimeter Question: A large rectangle divided into six identical squares has a perimeter of 30. What is the perimeter of one small square? Options: a. 8 b. 9 c. 10 d. 12
Rationale: The imagery emphasizes Mattie’s effort to synchronize her steps with Ethan’s longer stride, highlighting adjustment rather than mutual enthusiasm.
7. Sunset and Hemlock Descriptions Question: The descriptions in paragraph 2 are included to... Options: a. show fleeting time b. emphasize acute sensations c. foreshadow decline d. suggest peacefulness Correct Answer: b. emphasize the acuteness of two characters’ sensations Rationale: Vivid natural imagery amplifies the characters’ heightened emotional and sensory experiences, underscoring their intense connection.
8. Charles Dodgson Sentence Correction Question: British author Charles Dodgson... is renowned for when he wrote Alice’s Adventures in Wonderland. Options: a. NO CHANGE b. renowned in that he wrote c. received renown, he wrote d. is renowned for writing Correct Answer: d. is renowned for writing Rationale: "Renowned for writing" correctly follows the structure "renowned for + gerund." The original incorrectly uses "when he wrote."
9. Algebraic Equation Question: Solve (\sqrt{X - 3} + 5 = 9). Options: a. 3 b. 5 c. 16 d. 19 Correct Answer: d. 19 Rationale: Subtract 5: (\sqrt{X - 3} = 4). Square both sides: (X - 3 = 16), so (X = 19 ).
10. Confused Words Question: These are commonly confused words. Think carefully. Options: a. NO CHANGE b. affects of excess c. effects of access d. affects of access Correct Answer: a. NO CHANGE Rationale: "Effects of excess" is correct: "effects" (results) and "excess" (overabundance). Other options misuse "affects" (influences) or "access" (entry).
a. NO CHANGE b. passed their c. past there d. passed there Correct Answer: a. NO CHANGE Rationale: "Past" is a preposition meaning "beyond." "Passed" is a verb (e.g., "they passed the land"), which is incorrect here.
14. Margin of Error Question: Which sample reduces the margin of error? Options: a. 40 psychology students b. 40 random students c. 300 psychology students d. 300 random students Correct Answer: c. 300 randomly selected undergraduate psychology-degree program students Rationale: A larger sample size ((n = 300)) from the same population reduces variability and margin of error. To determine whether chimpanzees are more likely to delay gratification for a cooked food reward than they are for a raw food reward, cognition researchers Felix Warneken and Alexandra Rosati conducted an experiment comparing chimpanzees' decisions [1] in two situations: a "raw-delay" condition and a "cooked-delay" condition. In the raw- delay condition, Warneken and Rosati offered the chimpanzees a choice between receiving a piece of raw food immediately and waiting for one minute to receive three pieces of raw food; the chimpanzees chose the larger, delayed reward 60 percent of the time. In the cooked-delay condition, in which the chimpanzees could receive one piece of raw food immediately or wait one minute for three pieces of cooked food, they chose the larger, delayed reward approximately 85 percent of the time.

Which is the best punctuation choice to indicate that what follows is an elaboration or exampl - - correct ans- - a. NO CHANGE The measures of the angles of a triangle are in the ratio of 2x:3x:5x as illustrated below. What is the measure of the smallest angle in the triangle? a. 18 b. 20 c. 30 d. 36 - - correct ans- - d. 36 Looming above passersby in Lisbon, Portugal, a gigantic raccoon protrudes from the side of a building. A close look at this multimedia street sculpture reveals that the raccoon's eyes are made from discarded tires, its arms from dented bumpers, and its claws from assorted metal scraps. This larger-than-life 3-D street mural is the creation of Artur Bordalo, a Portuguese artist whose unusual animal sculptures made out of garbage are attracting international attention. That's exactly what Bordalo [1] wants. His goal is to: raise awareness about the destructive effects of excess consumerism. To that end, the broad appeal of the animal world serves Bordalo's purpose well. After the spectacle of the towering raccoon captures the interest of passersby, the sculpture's materials demand that viewers confront the waste products that are harming the natural world. Hint: A colon can be used to introduce an example or elaborati - - correct ans- - d. wants: his goal is to This passage is adapted from Fyodor Dostoevsky, The Brothers Karamazov originally published in 1880. Alyosha had been struck by Katerina Ivanovna's beauty when, three weeks before, Dmitri had first brought him, at Katerina Ivanovna's special request, to be introduced to her. There had been no conversation between them at that interview, however. Supposing Alyosha to be very shy, Katerina Ivanovna had talked all the time to Dmitri to spare him. Alyosha had been silent, but he had seen a great deal very clearly. He was
a. p b. p2 - 2 c. (p - 2) d. p2 - p - - correct ans- - d. p2 - p This passage is adapted from Christopher Intagliata, "Road Noise Takes a Toll on Migrating Birds." ©2015 by Scientific American. Building a road through wilderness certainly has a visibleimpact on local flora and fauna—you're physically paving over a slice of what was once habitat. But roads have less obvious effects, too. Like the introduction of traffic noise, which also takes a toll. "You can see an oil spill but you can't see a traffic noise spill. So convincing people that it's important is a little more difficult," said Heidi Ware. Ware is an ornithologist at the Intermountain Bird Observatory in Boise, Idaho. She and her colleagues studied the reactions by birds to the sounds of vehicles. And they did it without paving the great outdoors. Instead, they mounted 15 pairs of speakers on Douglas fir trees, along a ridge near Boise, and played traffic noise. They thus created what they call a "phantom road" throug - - correct ans- - b. Migration patterns start to change because the birds run out of energy sooner than they previously did. In the triangles above, 3(y - x) = a. 45 b. 60 c. 30 d. 15 - - correct ans- - a. 45 The following sentence is taken from a longer writing passage on the SAT. Read the sentence and determine which option expresses the information in the best way.
The writer wants to add the following sentence to the paragraph. The largest of the panderos—a hand drum called the seguidor—provides the pulse of the music. To make the paragraph most logical, the sentence should be placed HINT--Is there a place where information seems to be missing? a. before sentence 1 b. after sentence 2 c. after sentence 3 d. after sentence 8 - - correct ans- - b. after sentence 2 I f θ = 330 ∘ , w h a t i s t h e v a l u e o f θ i n r a d i a n s? HINT--Recall that there are2 πradians in one revolution of a circle. There are also 360 ∘in one revolution of a circle. This leads us to the following conversion: 2 πradians = 360 ∘. a. 3 π/ 2 b. 5 π/ 3 c. 7 π/ 4 d. 11 π/ 3 - - correct ans- - d. 11 π/ 3 The creation of today's animated films, frequently hailed for their lifelike artistry, relies heavily on mathematics. Animators use algorithms, or sequences of mathematical steps, to create, for instance, the rounded shapes making up an old man's knobby knuckles or a young girl's bouncy hair. One of the algorithms now considered an industry standard repeatedly subdivides a polygon by splitting and averaging the midpoint of a line. Developed by Pixar Animation Studio's Tony DeRose, this algorithm eliminated the problem of discernible edges of polygons by replacing them with the seamlessly rounded curves of the parabolas that emerge as a result of the polygon subdivision process. Innovations such as [1] DeRoses depend on an understanding of
d. more than 13 - - correct ans- - d. more than 13 To show how a common desk fan cools a person, Rhett Allain, a physics professor and writer for Wired magazine, performed a simple experiment. He wet a paper towel with warm water and wrapped it around a thermometer. Allain wrapped a second thermometer in a dry paper towel, and then he set both thermometers in front of a fan. Initially the fan was turned off. The temperature of the thermometer wrapped in the wet paper towel decreased—at first rapidly, then more slowly—and eventually dropped below room temperature. After the fan was turned on, the temperature of the wet thermometer plummeted another 30°C. By contrast, the temperature of the thermometer wrapped in the dry paper towel barely changed during the entire experiment. This experiment demonstrated the power of evaporation to cool wet objects, such as a sweaty person, and the role of a fan in making evaporation more effective. a. NO CHANGE b. continued its slow - - correct ans- - c. underwent another rapid decrease The circle shown above has center O and a radius of length 5. If the area of the shaded region is 20π, what is the value of x? HINT--You can figure out the area of the whole circle, since you know that the radius is 5. From the area of the whole circle and the area of the shaded part, it is possible to find the measure of the angle that has its vertex at point O and is in the right triangle. Once you find that angle measure, you can find the value of x. a. 18 b. 36 c. 45 d. 54 - - correct ans- - a. 18
