She found that increased acidity weakened the shells, making them more vulnerable to predators. However, Curie also observed that some snail species exhibited greater resilience, attributed to their unique protein composition. This suggests that while ocean acidification poses a threat, certain species may adapt through evolutionary mechanisms.  \nWhich choice best states the main idea of the text?  \nOcean acidification significantly weakens marine snail shells, increasing their risk of predation.  \nA 2018 study showed that only certain marine snail species are affected by increased ocean acidity.  \nMarine snails are developing unique protein compositions as a result of the increased ocean acidity.  \nOcean acidification weakens snail shells, but some species may adapt due to their protein composition.  \nQuestion 2  \nIn 2008, the National Portrait Gallery unveiled a painting of Barack Obama by artist Kehinde Wiley. Wiley is known for portraying contemporary Black subjects in the traditional style of European aristocratic portraiture. His portrait of Obama is no exception. Obama is seated in a chair, but he is surrounded by vibrant and colorful flowers, including chrysanthemums, representing Chicago; African lilies, representing Obama’s father; and jasmine, representing Hawaii. The Obama portrait is a striking example of Wiley’s signature style.  \nWhich choice best states the main idea of the text?  \nKehinde Wiley’s portrait of Barack Obama incorporates floral symbols relevant to Obama’s life and background.  \nKehinde Wiley is best known for his earlier portraits of aristocrats in Europe.  \nThe National Portrait Gallery has a large collection of portraits of prominent American leaders.  \nKehinde Wiley's Obama portrait exemplifies the artist's style of depicting Black figures in classic portraiture.  \nQuestion 3  \nArt transcends simple aesthetics, influencing society by sparking dialogue and challenging norms. Guernica, for example, by Pablo Picasso, vividly captures the horrors of war, prompting viewers to contemplate its devastating consequences. Similarly, Maya Angelou’s poems explored themes of identity and resilience, fostering empathy and understanding. Art becomes a mirror reflecting society's complexities.  \nWhich choice best states the main idea of the text?  \nArt primarily serves as a means of aesthetic expression, with limited social impact.  \nArt plays a significant role in shaping cultural understanding and provoking societal reflection.  \nMaya Angelou's poems are more influential than Pablo Picasso's paintings in promoting social change.  \nThe main purpose of art is to document historical events accurately and objectively.  \nQuestion 4  \nThe following text is from Mark Twain's 1884 novel The Adventures of Huckleberry Finn. In this passage, Huckleberry Finn describes meeting up with Tom Sawyer and other boys near the river at night.  \nWell, when Tom and me got to the edge of the hill-top we looked away down into the village and could see three or four lights twinkling, where there was sick folks, maybe; and the stars over us was sparkling ever so fine; and down by the village was the river, a whole mile broad, and awful still and grand. We went down the hill and found Jo Harper and Ben Rogers, and two or three more of the boys, hid in the old tanyard.  \nAccording to the text, what does the narrator observe about the river?  \n It is filled with boats and activity.  \n It is surprisingly narrow near the village.  \n It is rough and dangerous to cross.  \n It is very wide and appears calm.  \nQuestion 5  \nIn a 2018 study, Ashley Whillans found that people who prioritize time over money tend to report greater overall life satisfaction. Participants were asked to choose between two hypothetical scenarios: one that would save them time and another that would save them money.
