Question

Which of these is a hypothesis?

-Salmon are kept in their natural habitat and treated with fungicides whenever infected.
-The yield of salmon is 2,000 kilograms in the month of April and 1,500 kilograms in the month of October.
-Salmon are more prone to infections during the summer than in other seasons.

Answer 1

The answer is either the second sentence or the third, i believe it is the 3rd

Answer 2

Since the word hypothesis means an educated guess, I'd go with "Salmon are more prone to infections during the summer than in other seasons" because the others are just stating what it seems to be, facts.
