Where is the hypothesis in this passage?

for an exercise in scientific inquiry, clark posed a question about density. he wondered if the density affected the liquid's ability to retain heat. before determining an hypothesis, clark researched density he knew that the denser a liquid is the more molecules it

pretty sure for this one, "if the density affected the liquid's ability to retain heat."

Explanation:

a hypothesis should be in "if, then, because.." format, and while this bit of the passage doesnt include all three, it does include one! that bit of the passage would be an incomplete hypothesis.
