Re: Though most tennis players generally strive to strike the ba [#permalink]
Hi Carcass, Can you explain que 2? Why is the ans A when the passage establishes that hitting the centre of percussion helps avoid jolts? Why can't it be E?

EXPLANATION QUESTION #2

EXCEPT questions require you to validate the answer choices. Go through the choices one by one, labeling true answers with a T and the one false answer with an F. ​(A) ​CORRECT. False. This choice contradicts information given in the first paragraph: the center of percussion is only one of two sweet spots that minimize vibration. The vibration node is the other sweet spot. ​(B) ​True. The first paragraph introduces the concept that the impact can “strain” the player’s arm. ​(C) ​True. The second paragraph describes at least two different forces that act upon a tennis racket striking the ball: “translational,” as described in the second and third sentences, and “rotational,” as described in the fourth and fifth sentences.
(D) ​True. The fourth sentence of the second paragraph states that “unless the ball happened to hit the racket precisely at the racket’s center of mass, the racket would additionally experience a rotational motion.” The fifth sentence then reads: “Whenever the ball hits the racket face, the effect of this rotational motion will be to jerk the end of the handle forward, toward the ball.” ​(E) ​True. The second sentence of the second paragraph states that a racket will “bounce backward” after striking the ball; these words are synonyms for rebound.
