Answer:
The correct answer is letter "C": Books cannot teach you everything you need to know.
Step-by-step explanation:
Even though books are greats sources of knowledge, they are not enough when it comes to learning. Experience is the perfect complement of the theoretical information one can acquire by reading. As a matter of fact, by experience, we can prove if a certain theory is true or not. For instance, in science, a hypothesis requires experimentation to discard if what is thought applies. If it does after several studies, the hypothesis becomes a theory. So, as well as in science, in life one must experiment if that person wants to grow.
