Answer:

The scientist needs more supporting evidence.

Explanation:

The scientist only observed one chimpanzee, and no others. There is no way for certain for him to know that all chimpanzees use tools. In order for him to more reinforce his claim, he should observe several other chimpanzees and see if they also use tools. Once he has observed enough, then he can make a reinforced claim.
