The Sports Medicine Programs of the Olympic Training Center, a complex where final tryouts are held for athletes representing the United States in the Olympics, is geared toward enhancing athletes' performance and toward their preparation for international competition.
(A) is geared toward enhancing athletes' performance and toward their preparation
(B) is geared to enhance the performance of athletes and to prepare them
(C) are geared to enhance athletes' performance and their preparation
(D) are geared toward the enhancement of athletes' performance and toward preparing them
(E) are geared toward enhancing the performance of athletes and preparing them
The correct answer is E
I am not sure why the correct answer does not have "toward" after "and".
Also, I want to know when to use "X's Y" and when to use "Y of X".
In this case, I can not tell the difference between "athletes' performance" and "the performance of athletes".
Thank you so much!!
