Answer:
A.) If the temperature increases, then crickets will chirp more.
Step-by-step explanation:
The hypothesis is a testable statement that can be supported or disproved through experimentation.
A.) is correct. This statement clearly identifies what will (supposedly) happen when a variable is manipulated. Once an experiment is carried out, this hypothesis can be supported or negated.
B.) is incorrect. This is an opinion, not an objective statement. This statement is subjective and cannot be backed by evidence.
C.) is incorrect. Hypotheses are not questions. This statement also does not state how temperature could affect a cricket's chirp. However, questions can often lead to the formation of a hypothesis.
D.) is incorrect. The first part of the statement is an observation, and the second part is an assumption. Like in answer C, this information can be used as the basis in making a hypothesis.
