Question

the passage below describes an experiment. read the passage and then follow the instructions below. lemon juice can cause milk to curdle, or form solid clumps. anita mixed two cups of milk and four teaspoons of lemon juice in each of three pots. she used nonfat milk in one pot, low - fat milk in one pot, and full - fat milk in the third pot. anita put lids on the pots and left the mixtures to curdle on the stove over medium heat. after 20 minutes, she removed a small sample of curdled milk clumps from each pot and calculated the average clump size in each sample. anita repeated this process four times. identify the question that anitas experiment can best answer. does nonfat milk curdle faster than low - fat or full - fat milk when lemon juice is added? does the type of milk affect the sizes of clumps formed when the milk curdles? does stirring a mixture of lemon juice and milk affect the sizes of the curdled milk clumps?

Explanation:

Anita's experiment involves different types of milk (non - fat, low - fat, full - fat) and measures the average clump size. The first option is about the speed of curdling, which is not measured in the experiment. The third option is about stirring, which is not part of the experiment. The second option directly relates to the variable (type of milk) and the measured outcome (clump size).

Answer:

Does the type of milk affect the sizes of clumps formed when the milk curdles?
