You seem to forget including the choices in this question. Nevertheless, to help you, I could just tell what a superlative is so you could identify it on your own.
Superlatives are adjectives that are expressed in their greatest extent. For example, when you describe something so beautiful than any other thing you've ever seen, you describe it as 'most beautiful'. Another example is, if you've never been so happy in your life, you are the 'happiest'. So, generally, superlatives are written as a suffix -est or you add the word 'most' before the adjective.

According to the Scientific Method, in order to make a controlled experiment you NEED to have an hypothesis.
A controlled experiment consists of a test done by a scientist in which only one or a few variables are changed while the others remain constant in order to prove or disprove a hypothesis. This hypothesis is key to said experiment because it provides the starting point from which the professional can begin the procedure, as it helps focus on the subject that one is trying to get results from. Without a clear hypothesis, the outcome of the experimentation will not be valid nor specific.
The most important difference between an outline and a finished piece of writing is the "details", since at the outline state you should have the basics of each paragraph already worked out fairly well.
