Question

the passage below describes a process of scientific inquiry. select the part of the passage that describes revising the hypothesis. swings ellie pushed abby and abbys little brother, andy, on swings. ellie noticed that andy always swung back in less time than abby. ellie asked abby if she thought the weight on a swing was related to the time it took to return. to find out, abby stood back four feet and released a swing three times, once with a light weight attached to it, once with a medium weight, and once with a heavy weight. ellie measured how long it took the swing to go forward and back each time. they repeated the tests on ten swings. they decided that weight on a swing wasnt related to swinging time, since for each swing the time was similar with all three weights. then, ellie noticed that swings with shorter chains always swung back sooner. she thought that chain length would determine swinging time and that shortening a swings chains would shorten the time it took to swing back.

Explanation:

The initial hypothesis was about weight and swinging - time relationship. After the experiment disproved it, Ellie formed a new hypothesis about chain - length and swinging time. The part "She thought that chain length would determine swinging time and that shortening a swing's chains would shorten the time it took to swing back" shows the revision of the hypothesis.

Answer:

She thought that chain length would determine swinging time and that shortening a swing's chains would shorten the time it took to swing back.
