"The Sports Gene": Which of the following inferences about the jumping success of Stefan Holm is best supported by the last third of the excerpt? Question 15 options: a) Holm was a great high jumper because, like Donald Thomas, he had an exceptionally long Achilles tendon. b) Holm had a stiffer Achilles tendon that helped him jump to greater heights. c) Thomas passed Holm because Holm could not improve the height of his jumps after years of practice. d) Holm became an Olympic champion because of his hard work.

This question seems to be incomplete. However, there´s enough information to find the right answer.

Holm had a stiffer Achilles tendon that helped him jump to greater heights.

Explanation:

In the article "The Sports Gene," by David Epstein, the inference about the jumping success of Stefan Holm that is best supported is that it was Holm´s stiffer Achilles tendon that helped him jump to greater heights.

It´s not inferred that both Holm and Donald Thomas have an exceptionally long Achilles tendon. Nor that Holm was unable to improve the height of his jumps after years of practice.

there is no excerpt.

put the excerpt in the comments and ill answer.

i wonder if it is possible to place reagans testimony and paragragh 18, so we can compare and contract the ideas in the text.
