### HideShow timer Statistics

Physiological research has uncovered disturbing evidence linking a number of structural disorders to jogging. Among the ailments seemingly connected with this now-popular sport are spinal disk displacements, stress fractures of the feet and ankles, knee and hip joint deterioration, and tendonitis. Furthermore, these injuries do not occur exclusively among beginning runners—veteran joggers suffer an equal percentage of injuries. What the accumulating data suggest is that the human anatomy is not able to withstand the stresses of jogging.

Which one of the following is an assumption of the argument?

(A) The link between jogging and certain structural disorders appears to be a causal one.
(B) Jogging causes more serious disorders than other sports.
(C) The jogger’s level of experience is a factor determining the likelihood of a jogging injury.
(D) Some sports are safer for the human body than jogging.
(E) The human species is not very durable.

i guessed i missed this one. can you explain guys?

A.
(B) Jogging causes more serious disorders than other sports - no mention of other sports.
(C) The jogger’s level of experience is a factor determining the likelihood of a jogging injury - beginners as well as veterans suffer equally
(D) Some sports are safer for the human body than jogging- no mention of other sports.
(E) The human species is not very durable - very general statement which is to say that the statement is not specific to the argument of the passage

I think E
It's either E or C. A is out of scope because stem never talk about link casualness. In B and D, other sports are not mentioned; thus, out of scope. In C, the stem said that the likelihood is the same for both experience and non-experience; thus, this isn't true.
I think E is correct. If human is durable, then the conclusion will not hold true.

OA is A.

i misread "Furthermore, these injuries do not occur exclusively among beginning runners—veteran joggers suffer an equal percentage of injuries" as ""Furthermore, these injuries do not occur among beginning runners but occure only to veteran joggers".

ok
but please explain how A can be an assumption here????

The only reason I think why "A" is correct because the link "cause->effect" may possibly be opposite. People who have these physiological abnormality participate in sprinting more than the other people.

Author makes this argument:
"The human anatomy is not able to withstand the stresses of jogging."

Author thinks:
Running caused these conditions. (Pretty much what's said in A)

Think of a scenario:
People who run also do weights. Thus, the people who run have these injuries. There is a link for sure. But, saying that running caused those condition would be bad. Doing weight could have caused the injuries.

Ans: "A"

The question only shows correlation between injuries and the sport but there is no causation. But the conclusion "What the accumulating data suggest is that the human anatomy is not able to withstand the stresses of jogging." shows that they are causing the injuries. So, the assumption must be causation holds true.

I hope this explanation helps.

IF am not wrong then in assumption questions the conclusion remains the same it just gets strengthened

now if we take up A as an assumption then will our conclusion become strengthened?????????

I believe you are half right. You have to find out what is missing to ensure that the conclusion is correct.
Conclusion is strengthened in a strengthened or support type of questions.
