Jan Gimsa, Robert Sleigh, and Ulrike Gimsa have hypothesized that the sail-like structure running down the back of the dinosaur Spinosaurus aegyptiacus improved the animal's 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 Gimsa and colleagues' hypothesis?
  • 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.
Correct answer is option 'D'. Can you explain this answer?

Jan Gimsa, Robert Sleigh, and Ulrike Gimsa have hypothesized that the ...
First we need to focus in on the hypothesis our evidence needs to support:
"the sail-like structure running down the back of the dinosaur Spinosaurus aegyptiacus improved the animal's success in underwater pursuits of prey species capable of making quick, evasive movements"
We can simplify this hypothesis to make our lives a bit easier:
Sail on back = quicker movements
Which choice strengthens this idea?
Choice A does focus on speed of movement, but finds that a sail on the back = slower movement. This is the opposite of what we want to support. We can eliminate this choice.
Choice B focuses on water displacement, not the speed of movement. We can eliminate this choice.
Choice C focuses on the "power" needed to move, not the speed of movement. We can eliminate this choice.
Choice D focuses on speed of movement, and finds that having a sail made sharp turns take "significantly less time". In other words: sail on back = quicker movements. This supports the hypothesis made by the scientists. Choice D is the answer.
