Can we draw the following hypothesis from the context (see options)? 

Context:

How to wake up in the middle of the night<br>Practice by waking up at the same time for a month. Nerves in your brain control your body's clock, known as your circadian rhythm. This rhythm is established by following a predictable routine, which is why you are able to wake up at the same time on the weekend as you are during the week if all factors are equal.

Hypothesis: You will have to change when you eat if you change your sleep pattern.
