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.

Question is based on the following passage and supplementary material.This passage is adapted from Geoffrey Giller, “Long a Mystery, How 500-Meter-High Undersea Waves Form Is Revealed.” ©2014 by Scientific American.Some of the largest ocean waves in the world arenearly impossible to see. Unlike other large waves,these rollers, called internal waves, do not ride theocean surface. Instead, they move underwater,5 undetectable without the use of satellite imagery orsophisticated monitoring equipment. Despite theirhidden nature, internal waves are fundamental partsof ocean water dynamics, transferring heat to theocean depths and bringing up cold water from below.10 And they can reach staggering heights—some as tallas skyscrapers.Because these waves are involved in ocean mixingand thus the transfer of heat, understanding them iscrucial to global climate modeling, says Tom15 Peacock, a researcher at the Massachusetts Instituteof Technology. Most models fail to take internalwaves into account. “If we want to have more andmore accurate climate models, we have to be able tocapture processes such as this,” Peacock says.20Peacock and his colleagues tried to do just that.Their study, published in November in GeophysicalResearch Letters, focused on internal waves generatedin the Luzon Strait, which separates Taiwan and thePhilippines. Internal waves in this region, thought to25 be some of the largest in the world, can reach about500 meters high. “That’s the same height as theFreedom Tower that’s just been built in New York,”Peacock says.Although scientists knew of this phenomenon in30the South China Sea and beyond, they didn’t knowexactly how internal waves formed. To find out,Peacock and a team of researchers from M.I.T. andWoods Hole Oceanographic Institution worked withFrance’s National Center for Scientific Research35 using a giant facility there called the CoriolisPlatform. The rotating platform, about 15 meters(49.2 feet) in diameter, turns at variable speeds andcan simulate Earth’s rotation. It also has walls, whichmeans scientists can fill it with water and create40accurate, large-scale simulations of variousoceanographic scenarios.Peacock and his team built a carbon-fiber resinscale model of the Luzon Strait, including the islandsand surrounding ocean floor topography. Then they45 filled the platform with water of varying salinity toreplicate the different densities found at the strait,with denser, saltier water below and lighter, lessbriny water above. Small particles were added to thesolution and illuminated with lights from below in50order to track how the liquid moved. Finally, theyre-created tides using two large plungers to see howthe internal waves themselves formed.The Luzon Strait’s underwater topography, with adistinct double-ridge shape, turns out to be55 responsible for generating the underwater waves.As the tide rises and falls and water moves throughthe strait, colder, denser water is pushed up over theridges into warmer, less dense layers above it.This action results in bumps of colder water trailed60by warmer water that generate an internal wave.As these waves move toward land, they becomesteeper—much the same way waves at the beachbecome taller before they hit the shore—until theybreak on a continental shelf.65 The researchers were also able to devise amathematical model that describes the movementand formation of these waves. Whereas the model isspecific to the Luzon Strait, it can still helpresearchers understand how internal waves are70generated in other places around the world.Eventually, this information will be incorporated intoglobal climate models, making them more accurate.“It’s very clear, within the context of these [globalclimate] models, that internal waves play a role in75 driving ocean circulations,” Peacock says.Q.According to Peacock, the ability to monitor internal waves is significant primarily because

Although many transposons, DNA sequences that move within an organisms genome through shuffling or duplication, have become corrupted and inactive over time, those from the long interspersed nuclear elements (LINE) family appear to remain active in the genomes of some species. In humans, they are functionally important within the hippocampus, a brain structure that supports complex cognitive processes. When the results of molecular analysis of two species of octopus—an animal known for its intelligence—were announced in 2022, the confirmation of a LINE transposon in Octopus vulgaris and Octopus bimaculoides genomes prompted researchers to hypothesize that that transposon family is tied to a species capacity for advanced cognition.Which finding, if true, would most directly support the researchers hypothesis?
