Question

For healthy individuals who wish to improve their overall fitness, cross training in several sports is more beneficial than training in a single activity. Cross training develops a wide range of muscle groups, while single sport training tends to isolate a select few muscles. Single sport activities, especially those that target slow-twitch muscles, tend to increase the tonic muscle fibers in the body. Cross training works instead to increase the body’s phasic muscle fibers, which burn more calories than tonic muscle fibers.

Which one of the following, if true, best supports the argument above?

(A) In healthy persons, overall fitness increases in proportion to the number of calories burned by the body.
(B) Overall fitness is most effectively improved through athletic training.
(C) Tonic muscle fibers are of greater value to overall fitness than are phasic muscle fibers.
(D) Strenuous physical exertion on a single sport is not recommended for those recovering from a serious illness.
(E) Some slow-twitch muscles contain many phasic muscle fibers.

(A) In healthy persons, overall fitness increases in proportion to the number of calories burned by the body.
 Yes, as it is stated by giving the example and differentiating between Tonic and phasic muscle fiber.

(B) Overall fitness is most effectively improved through athletic training.
 We don't know which all muscles are affected by athletic training, we can't infer that.

(C) Tonic muscle fibers are of greater value to overall fitness than are phasic muscle fibers.
 Just the opposite.

(D) Strenuous physical exertion on a single sport is not recommended for those recovering from a serious illness.
 The passage is about healthy individuals we cannot infer anything about those recovering from serious illness.

(E) Some slow-twitch muscles contain many phasic muscle fibers.
 We cannot infer that.

Which one of the following, if true, best supports the argument above?

summary: overal fitness burn more calories because of phasic muscle fibers (multipl sport) rather than tonic muscles , which is increased due to slow twitch muscles( single sport)
(A) In healthy persons, overall fitness increases in proportion to the number of calories burned by the body.

P - 1) Cross Training - Wide muscles and Body phasic muscle fibre therefore burn more calories 2) Single training - Single muscle and Tonic muscle fiber
C - Therefore, Cross better than single for overall fitness
Pre thinking - 1) More Body phasic muscle boosts overall fitness 2) More calories burns in Cross than Single which helps improve overall Fitness

(A) In healthy persons, overall fitness increases in proportion to the number of calories burned by the body. = Correct!
(B) Overall fitness is most effectively improved through athletic training. = Out of scope.
(C) Tonic muscle fibers are of greater value to overall fitness than are phasic muscle fibers. = Weakner.
(D) Strenuous physical exertion on a single sport is not recommended for those recovering from a serious illness. = Irrelevant
(E) Some slow-twitch muscles contain many phasic muscle fibers. - Out of Scope
