Answer:
D. Making a prediction.
Explanation:
In many cases, the words "hypothesis" and "prediction" are used in the same context. However, in science, they do not have the same meaning.
A hypothesis is an <u>intelligent, testable, and possible explanation that is based on facts</u>. It analyzes the correlation between different variables.
A prediction, on the other hand, is usually <u>based on little or simpler information instead of experiments or scientific facts and are generally related to future events, therefore, in many cases, they tend to start with the word "If" or have the word "then" on the statement.</u>
In this case, "<em>If ferns need warm weather to grow, ferns in the warmer areas will grow faster</em>," this is a simple prediction that is not necessarily based on scientific facts. It is making a possible prediction or pure guess. This is also illustrated by the usage of "if" on it.
