Question

the passage below describes a process of scientific inquiry. select the part of the passage that describes developing a hypothesis.
a football game
samuel 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, samuel 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, samuel thought that perhaps his average heart rate was higher on offense because he moved more quickly in those positions.

A hypothesis is a testable prediction based on initial observation or reasoning. In the passage, Samuel forms a specific, testable claim about how his football position impacts his heart rate before collecting data.

Answer:

"He believed that since he ran longer distances on defense, his average heart rate would be higher when playing defensive positions."
