Question

on the reading and writing section of your sat, some questions will introduce a claim about an unfamiliar subject. the question will then ask you to identify the piece of evidence that most strongly supports that claim. textual evidence questions will look like this: textual evidence: example jan gims a, robert sleigh, and ulrike gims a have hypothesized that the sail - like structure running down the back of the dinosaur spinosaurus aegyptiacus improved the animals success in underwater pursuits of prey species capable of making quick, evasive movements. to evaluate their hypothesis, a second team of researchers constructed two battery - powered mechanical models of s. aegyptiacus, one with a sail and one without, and subjected the models to a series of identical tests in a water - filled tank. which finding from the model tests, if true, would most strongly support gims a and colleagues hypothesis? choose 1 answer: a the model with a sail took significantly longer to travel a specified distance while submerged than the model without a sail did. b the model with a sail displaced significantly more water while submerged than the model without a sail did. c the model with a sail had significantly less battery power remaining after completing the tests than the model without a sail did. d the model with a sail took significantly less time to complete a sharp turn while submerged than the model without a sail did.

Explanation:

The hypothesis is that the sail - like structure improved the dinosaur's success in underwater pursuits of evasive prey. A key aspect of success in such pursuits would be the ability to make quick, sharp turns. If the model with the sail took significantly less time to complete a sharp turn while submerged than the model without a sail, it would support the idea that the sail enhanced the dinosaur's underwater maneuverability, which is relevant to its success in pursuing evasive prey. Options A, B, and C are not directly related to the dinosaur's success in pursuing prey through underwater maneuvers.

Answer:

D. The model with a sail took significantly less time to complete a sharp turn while submerged than the model without a sail did.
