求解答以下问题：
Which one of the five experimental outcomes, if added to the information
given, would most strengthen the evidence for the scientist's conclusion?
There were three enclosures, two of which contained a dog. Only one of these
contained a familiar dog. The dogs released more food to familiar dogs than to
unfamiliar dogs. The scientists thereby concluded that dogs are more
motivated to help familiar dogs than they are to help unfamiliar dogs. However, it is possible that releasing the food to the familiar dog could have
been motivated by other reasons. For example, the dog could simply be trying
to communicate with the familiar dog rather than necessarily trying
specifically to help this dog. If the dogs released more food to a familiar dog while it was contained in an
enclosure than when it was not enclosed yet nearby and visible, this would
strengthen the idea of trying to “help” the other dog. A. This information would weaken the scientist's argument. It introduces
information suggesting the presence of a confounding variable in the
experimental setup. That is, if the behavior was encouraged by a familiar

person, we would not be able to tell whether it was this person's presence
or the presence of the other dog that increased the behavior. B. This would suggest that the dog's activation of the lever was not
contingent on providing food to another animal. In other words, if the dog
provides food even when there is no animal to provide food for, then it
follows that the presence of the other dog is irrelevant to this behavior. C. The experimental setup described here introduces the factor of
friendliness. Adding this extra factor could easily confound testing of the
original hypothesis, which suggested that simple familiarity increased the
behavior. D. The experimental setup described here introduces a factor of food interest. Adding this extra factor could easily confound testing of the original
hypothesis, which suggested that simple familiarity increased the
behavior. E. Correct. This information would strengthen the hypothesis that a desire
to help a familiar dog was operative in the dog's behavior.
