In Europe, schoolchildren devote time during each school day to calisthenics. North American schools rarely offer a daily calisthenics program. Tests prove that North American children are weaker, slower, and shorter-winded than European children. We must conclude that North American children can be made physically fit only if they participate in school calisthenics on a daily basis.
Which one of the following is assumed in the passage?
(A) All children can be made physically fit by daily calisthenics.
(B) All children can be made equally physically fit by daily calisthenics.
(C) Superior physical fitness produces superior health.
(D) School calisthenics are an indispensable factor in European children’s superior physical fitness.
(E) North American children can learn to eat a more nutritious diet as well as to exercise daily.
According to the passage--we must conclude that A(North American children can be made physically fit) only if B(they participate in school calisthenics on a daily basis)--we should prove that B is a sufficient condition to A.So the assumtion must demonstrate that participating in school calisthenics on a daily basis lead to superior physical fitness, namely that, there is a GAP between school calisthenics and physical fitness.
But how to rule out the choice A. If A is not true, we also can not draw the conclusion.
只要北美和南美孩子能够通过体操健身就可以
并不需A说的全部孩子
U're right, I do not pay attention to "ALL", the negative of the "all" should be "some"
Thx!
the negative of "all" is "not all", "some" is "none" .
请问All children can be made physically fit by daily calisthenics这句话取非之后
是Not all children can be made physically fit by daily calisthenics
还是 Some children can be made physically fit by daily calisthenics
还是Some children can not be made physically fit by daily calisthenics
谢谢哪位帮助一下
Let analysis this problem:
Premise 1: In
Premise 2: North American schools rarely offer a daily calisthenics program.
Premise 3: Tests prove that North American children are weaker, slower, and shorter-winded than European children.
Conclusion: We must conclude that North American children can be made physically fit only if they participate in school calisthenics on a daily basis.
Which one of the following is assumed in the passage?
This is an assumption question, for assumption question you have to bridge between premise and conclusion because there is a missing link. the missin link for this problem is that you have to prove calisthenics is the major reason European schoolchildren are physically fit, not any other reasons. If there is another reason that makes European schoolchildren physically fit, then the conclusion can not stand.
make sure you are focus on the conclusion and be able to find out the conclusion after you read the whole question.
(A) All children can be made physically fit by daily calisthenics.
This is paraphrase one of our premise.
(B) All children can be made equally physically fit by daily calisthenics.
This answear is not related to the question, the argument did not mention any thing related to “equally physically fit”.
(C) Superior physical fitness produces superior health.
This is not related to our question at all. The question never mentioned about superior physical fitness.
(D) School calisthenics are an indispensable factor in European children’s superior physical fitness.
This is the right answear, it excludes other reasons that make sure School calisthenics is the major reason European schoolchildren are physically fit.
If you negate this: “School calisthenics are not an indispensable factor in European children’s superior physical fitness.” Which will weaken the argument a lot that the conclusion can not stand.
(E) North American children can learn to eat a more nutritious diet as well as to exercise daily.
This not related to our argument. The argument did not mention diet at all.
All children can be made physically fit by daily calisthenics
这句话取非之后是
Not all children can be made physically fit by daily calisthenics
Some children can be made physically fit by daily calisthenics
Logically, Not all is the same as Some
