Question

the passage below describes an experiment. julia divided 20 slices of fresh bread evenly between two boxes of equal size. she placed lids on the boxes so that the bread slices were not exposed to light. julia stored one box at 55°f and the other at 85°f. after ten days, she counted the number of moldy bread slices. she repeated this test four times. identify the question that the experiment can best answer. is the number of mold species that grow on bread stored at 55°f higher than the number of mold species that grow on bread stored at 85°f? do more bread slices get moldy when bread is stored at 55°f or at 85°f?

Explanation:

Julia's experiment varies the storage temperature of bread (55°F and 85°F) and counts the number of moldy bread - slices. So, it aims to find out if temperature affects the number of moldy bread - slices.

Answer:

Do more bread slices get moldy when bread is stored at 55°F or at 85°F?
