Question

the passage below describes an experiment. read the passage and then follow the instructions below. rock candy is a treat made by allowing sugar crystals to form on sticks. emma began making rock candy by adding one cup of hot water to each of eight glass jars. she dissolved equal amounts of white sugar in half of the jars and brown sugar in the other half of the jars. emma hung one identical wooden stick from the top of each jar, making sure that two inches of each stick were submerged in the sugar solution. emma left the jars in a cupboard for one week, allowing rock candy to form on the sticks. then, she measured the size of the rock candy on each stick. identify the question that emmas experiment can best answer. does the amount of sugar in the sugar solution affect the size of rock candy? does the type of sugar used to make rock candy affect whether the candy forms after three days? does rock candy grow larger when it is made with white sugar or brown sugar?

Explanation:

Emma's experiment has variables of white sugar and brown sugar. The outcome measured is the size of rock candy. The first option is about amount of sugar (not type), the second option is about whether candy forms (not size). The third option is about which sugar (type) makes rock candy larger (size), which matches the experiment's setup.

Answer:

Does rock candy grow larger when it is made with white sugar or brown sugar?
