Question ID:PT1 S4 Q15 Passage:Studies of brain lateralization in animals have purported to show that, whereas most human beings are right-handed, about half of any given group of animals will be “left-handed” (i.e., showing a preference for their left limbs) and half will be “righthanded.” This finding is suspect, however; it has long been noted that dogs will almost always “shake hands” with the right paw. Stem:Which one of the following, if true, is the strongest defense against the counterexample of dogs that “shake hands”? Correct Answer Choice:EChoice A:Dogs are observed to scratch themselves with the left leg as well as with the right leg. Choice B:People who observe dogs “shaking hands” are observing a behavior that dogs perform only with a front paw. Choice C:Left-handed people sometimes feel inconvenienced or even stigmatized in a “right-handed world,” but dogs face no analogous difficulties. Choice D:Dogs that have lost a limb are able to compensate for the loss, regardless of whether the limb was lost from the right or left side. Choice E:In learning to perform tricks, dogs are influenced by the behavior of their trainers.
