According to the article titled “enlightenment,” philosophers believed that human beings had the ability to which no other creature possessed.
a.
learn
b.
reason
c.
understand
d.
communicate

   B. Reason

Explanation:  What makes human beings apart from others is reason, since, for example, animals have the ability to communicate and learn many skills of hunting, hiding, etc. According to Enlightenment philosophers, human beings have reason, as a natural ability based on natural laws.
