Question

Handedness, a preferential use of either the right or left hand, typically is easy to observe in humans. Because this trait is present but less blank in many other animals, animal-behavior researchers often employ tasks specially designed to reveal individual animals’ preferences for a certain hand or paw.

Which choice completes the text with the most logical and precise word or phrase?

Accepted Answer

Choice A is the best answer because it most logically completes the text&rsquo;s discussion about handedness in animals. As used in this context, &ldquo;recognizable&rdquo; means apparent or identifiable. The text indies that handedness is &ldquo;easy to observe in humans,&rdquo; but that animal-behavior researchers use special tasks to determine handedness in other animals. This context and the use of &ldquo;less&rdquo; before the blank indie that compared with handedness in humans, handedness in other animals is less recognizable. Choice B is incorrect because there&rsquo;s nothing in the text to suggest that handedness is less &ldquo;intriguing,&rdquo; or fascinating, in nonhuman animals than it is in humans. The text focuses on how easy it is to observe handedness in humans as compared with other animals; the text doesn&rsquo;t suggest that handedness is more fascinating in humans. Choice C is incorrect because there&rsquo;s nothing in the text to suggest that handedness is less &ldquo;significant,&rdquo; or important or meaningful, in nonhuman animals than it is in humans. The text focuses on how easy it is to observe handedness in humans as compared with other animals; the text doesn&rsquo;t suggest that handedness is more significant in humans. Choice D is incorrect because &ldquo;useful,&rdquo; or functional or helpful, wouldn&rsquo;t make sense in context. The text focuses on the ease with which researchers can determine whether an animal or person is right- or left-handed, not on how useful handedness in nonhuman animals is compared with handedness in humans.
