Statement:
There is one thing as important as studying and that is how much is understood.
Assumptions:
I. Studying and understanding go hand in hand.
II. Understanding is as important as studying.

The statement says that studying is important, but understanding what is studied is just as important. This means that simply reading or memorizing information is not enough; one must also comprehend it.

Now, let’s look at the assumptions. The first assumption says that studying and understanding always happen together. However, this is not necessarily true. A person can study without fully understanding, so this assumption is not implicit.

The second assumption states that understanding is as important as studying. This matches exactly with what the statement says, so this assumption is implicit.

Therefore, only the second assumption is implicit.
