<p>I dunno if this CR question is in the BB, but here is the small excerpt:</p>
<p>“The study on rats, kittens, and mice may, for instance, provide a physiological explanation for why infant animals employ in their play the same kinds of behavior that they will later use as adults. By stalking and capturing imaginary prey over and over again, a kitten builds its muscle and brain connections in a way that allows it to perform those actions later in life.” </p>
<li>The principle illustrated in lines 43-46 (" By stalking…life") is best conveyed by which additional example?</li>
</ol>
<p>A. Some puppies play only with their siblings.
B. A toddler prefers to play with one particular toy.
C. A lion is trained to jump through a hoop.
D. Young monkeys chase each other up and down a tree
E. Certain species of birds migrate south every fall.</p>
