Question

the passage below describes a process of scientific inquiry. select the part of the passage that describes revising the hypothesis. hint: to revise the hypothesis, you use the results of the investigation to come up with a new explanation. as aaron opened a can of soda, he remembered hearing that soft drinks are fizzy because there is carbon dioxide dissolved in them. he knew that sugar and salt dissolve better in hot liquids, so he reasoned that hot soft drinks can dissolve more carbon dioxide and will therefore be fizzier. so aaron got nine identical cans of soda. after opening them, he left three in the refrigerator, three on the kitchen counter, and three outside in the hot sun. five hours later, he took a sip from each can. to his surprise, the cold sodas were the fizziest, while the hot ones had gone flat! based on his experiment, aaron determined that cold soft drinks are fizzler than hot soft drinks. he reasoned that gases, like carbon dioxide, must dissolve differently than solids, like salt and sugar. at a cookout the next day, aaron told his friends to keep their sodas in the shade to help the sodas stay fizzy.

Explanation:

Aaron initially hypothesized that hot soft drinks would be fizzier (based on sugar/salt dissolving better in hot liquids). But after the experiment (cold sodas were fizzier), he used the results (cold = fizzier) to come up with a new explanation (gases dissolve differently than solids). The part "He reasoned that gases, like carbon dioxide, must dissolve differently than solids, like salt and sugar" shows him revising the hypothesis.

Answer:

He reasoned that gases, like carbon dioxide, must dissolve differently than solids, like salt and sugar.
