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.

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.

(B) Doing the equivalent of an hour of brisk walking two or three times a week generally produces dramatic improvements in cardiovascular 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.

(D) Aside from exercise, there is no way of improving one's cardiovascular health.

(E) To obtain a dramatic improvement in one's cardiovascular health, one must exercise strenuously at least occasionally.

A

A) Super safely worded. "Doing this CAN produce that". Seems supportable. We know that exercising even moderately on most days of the week can get you cardiovascular benefits. And we know that more vigorous (strenuous) exercise is even more effective than that. If modest amounts (most days of the week) can produce dramatic improvements, and vigorous exercise is more effective, then we have good support for (A).

B) More dangerous wording: "doing this GENERALLY produces that". Also, we were told that half an hour on at least 4 days a week would do it. This is talking about doing twice as long half as frequently. Yes, that may add up to the same total of hours, but maybe there's something crucial about exercising more than two days a week.

C) Dangerous wording: "____ is AT LEAST AS GREAT as ____". This also seems to go against the gist that strenuous is "MORE effective".

D) Super dangerous wording: "There is NO WAY". That's crazy. Nothing we read was that extreme.

E) Super dangerous: "To obtain ___ one MUST do ____". Nothing we read suggested that strenuous exercise was necessary. In fact, it said the opposite.

Takeaway/Pattern: Knowing that strong and comparative language is inherently sketchy on Inference answer choices, we can quickly filter (D) and (E) out of initial consideration. (B) is not AS strongly worded, but it's still stronger than (A) or (C). Once we try to support (A) vs. (C), we can see how (A) is supportable by combining what we know about moderate exercise with the claim that vigorous exercise is more effective.

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
