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. matt plays for his local football team. he was curious how the different positions he plays affect his average heart rate. he believed that since he ran longer distances on defense, his average heart rate would be higher when playing defensive positions. for several weeks, matt tracked his heart rate and the positions he played. he discovered that his average heart rate when playing on offense, at 124 beats per minute, was higher than his average heart rate when playing on defense, at 115 beats per minute. based on his results, matt thought that perhaps his average heart rate was higher on offense because he moved more quickly in those positions.

Explanation:

The hypothesis was that average heart - rate was higher on defense due to longer running distances. After tracking heart - rate and positions, the result showed higher average heart - rate on offense. Based on this result, Matt formed a new explanation about quicker movement on offense, which is revising the hypothesis.

Answer:

Based on his results, Matt thought that perhaps his average heart rate was higher on offense because he moved more quickly in those positions.
