Question

what are \textual evidence\ questions? 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: jan gizma, robert singh, and urfa gizma have hypothesized that the sail - like structure running down the back of the dinosaur spinosaurus improved the animals success in underwater pursuits of prey species capable of making quick, evasive movements. to test their hypothesis, a second team of researchers constructed two battery - powered mechanical models of a s. agulhasensis, 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 gizma and colleagues hypothesis? choose 1 answer: the model with a sail took significantly longer to travel a specified distance while submerged than the model without a sail did. the model with a sail displaced significantly more water while submerged than the model without a sail did. the model with a sail had significantly less battery power remaining after completing the tests than the model without a sail did. the model with a sail significantly less often made a sharp turn while submerged than the model without a sail did.

Explanation:

Textual - evidence questions ask for the evidence that best supports a claim. In this case, the claim is about the sail - like structure improving the animal's success. The model with a sail taking significantly longer to travel a specified distance while submerged shows an advantage of the sail structure, as it implies better movement or efficiency, thus supporting the hypothesis.

Answer:

The model with a sail took significantly longer to travel a specified distance while submerged than the model without a sail did.
