A and E go out of scope.

C seems right.

Which of the following, if true, most strengthens the argument?



A) Doctors who are general practitioners rather than orthopedists are less likely than orthopedists to judge the stability of an ankle fracture correctly.

Out of scope. Elimintate.
B) Many ankle injuries for which an initial x-ray is ordered are revealed by the x-ray not to involve any fracture of the ankle.

Don't care. Eliminate.
C) X-rays of patients of many different orthopedists working in several hospitals were reviewed.

This tells us that the follow up xrays that were reviewed were not specific to one doctor but several different orthopedists. This further strengthens the claim. Keep.
D) The healing of ankle fractures that have been surgically repaired is always checked by means of a follow-up x-ray.

Not talking about surgically repaired fractures. Eliminate.

E) Orthopedists routinely order follow-up x-rays for fractures of bone other than ankle bones.
So? Don't care. Eliminate.


Answer = C

C) X-rays of patients of many different orthopedists working in several hospitals were reviewed.


This plugs a hole in the argument; what if only the records of a single orthopedist or hospital were reviewed.

E says:

This is not related to 'ankle fractures that are initially judged stable'.

Our objects of interest are ankle fractures that are initially judged stable, NOT ankle fractures.

So that makes E out of scope.

choice C

X-rays of patients of many different orthopedists working in several hospitals were reviewed.

this suggests the x-rays were conducted on a widespread basis,thus helping the conclusion.

I agree...as none of the other choices make sense...If anyone sees a spark in any of the other answers please post.

I'd say C.

More reviews, stronger argument.

THough C looks good to me, I'm slightly lean towards B.

Reason: B refers completely about the ankle fracture and that is the argument to strengthen here.

C

B is explicitly mentioned in the para ... and C strengthens the argument by showing records of different orthopedist and hospitals .. all are revealing the same result

C. Shows that the results of the study were a representative sample of ankle fractures.

B was a contender but it is referring to initial x-rays. We dont care about the initial x-ray, only about whether the follow up x-rays are necessary. I think choosing B would require a large stretch to make it relevent to the actual arg. therefore incorrect.

OA?

it has to be C, The way to strengthen this argument is to strengthen the reliability of the evidence. If this is not included, it could have just been just one doctor at one hospital who misjudged all the diagnosis. Knowing there is a representative sample alleviates this problem.

I think its A
Because if orthopedists can judge the stability correctly then there is no point in doing X-ray many times.
