Modest amounts of exercise can produce a dramatic improvement in cardiovascular health. One should exercise most days of the week, but one need only do the equivalent of half an hour of brisk walking on those days to obtain cardiovascular health benefits. More vigorous exercise is more effective, but a strenuous workout is not absolutely necessary.
So exercise boosts cardio health. brisk walk on workout days make those excercises more effective. the more intensive work out is the better results are. But strenuouns work out is not absolutely nenessary. Which one of the following is most strongly supported by the statements above?
(A) Having a strenuous workout most days of the week can produce a dramatic improvement in cardiovascular health.
(CORRECT: since it is only mentioned is in the argument " strenuouns work out is not absolutely nenessary" that doesnt mean one must not do it, Hence for those who are not afraid of working out hard, strenuous work out can produce dramatic improvement)
(B) Doing the equivalent of an hour of brisk walking two or three times a week generally produces dramatic improvements in cardiovascular health.
( FALSE. ONLY BRISK WALK ALONE DOESNT IMPROVE CARDIO HEALTH)
(C) It is possible to obtain at least as great an improvement in cardiovascular health from doing the equivalent of half an hour of brisk walking most days of the week as from having a strenuous workout most days of the week.
( THIS INFORMATION IS NOT GIVEN. CANT BE ASSUMED) (D) Aside from exercise, there is no way of improving one's cardiovascular health.
( CANT ASSUME THIS, THERE ARE MANY OTHER WAYS I THINK
)
(E) To obtain a dramatic improvement in one's cardiovascular health, one must exercise strenuously at least occasionally.
( THIS IS TOO EXTREME, CANT BE SURE OF "MUST" OR MAYBE "IT IS DESIRABLE" ) HENCE OUT
