Assumption: Ankle fracture judged stable - is diagnosed accurately so doesnt require any follow up x-rays

A seems close to tht....


A is out of scope because General Practitioners are not mentioned. The argument is talking about Orthopedists so what the General Practitioners do is irrelevant.

Even if you could make a broad assumption that the argument is referring to all doctors then this would weaken the argument if anything because there would then be a need to do follow up xrays because the General Practitioners cant accurately judge the ankle fracture intially.

To me, E is the answer.

The argument is over whether its a wastage of money to go for follow up X ray for Ankle fracture.

E says that follow X rays is for bone fracture and not for ankle fracture. Which means, follow us for Ankle fracture X ray will lead to waste of money.


please correct me if I am wrong.

If the xrays that are mentioned in the argument are really being done to look at a fracture to a bone other then the ankle, then the evidence the author uses to justify his conclusion is false. False evidence cannot support a conclusion, it weakens it.

I think this one has been posted b/f. I say B.

JDMBA - thanks but still I have question related to answer C.

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

Does it means that X rays from orthopedists suspected whether its true or false and hence gone for review????

No this is not what it is saying.

The author is taking data and drawing a specific conclusion from it. Whenever you see a survey, sample, poll, etc. You should always be suspect of whether the data is representative of the whole.

For instance, if you read about polls for presidentail elections back in the 1920's the polls would indicate that a certain president would win by an overwhelming majority. However, the polls were conducted via telephone and only wealthy citizens had a telephone and the conclusion reached by the poll was not representative of the total population. Hence the prediction was wrong.

In the case of this argument, the author points to a sample of Xrays that were done a second time and the injury was always healed. What if this sample is only from the Worlds Greatest Orthopedist? Would the data gathered from this Orthopedist be representative of all Orthopedists? No. This would make it impossible for anyone to make a conclusion that 2nd xrays should never be done.

So by saying that the data is gathered from "many different orthopedists working in several hospitals", you are confirming that the data is representative and therefore strengthening the argument by eliminating the possibilty that the data is representative of only the Worlds Greatest Orthopedist.

Definitely C.

A. though could be considered "strengthening," is out of scope
B. is irrelevant because it's talking about ankle injuries in general and not just fractures
C. increases the credibility of the study by showing that it's a sample from a diverse population
D. is irrelevant because it's talking about surgically repaired ankle fractures
E. is irrelevant because it doesn't say anything about ankle fractures

If OA is B then all of us are failed finally :-)
After re-reading option B, I really realised it clearly says that X ray report has told at the beginning itself that there is no fracture in ankles.

This is what CR is -- anything can happen.

Q 22: Often patients with ankle fractures that are stable, [#permalink] New post 24 Oct 2007, 10:47
Q 22:
Often patients with ankle fractures that are stable, and thus do not
require surgery, are given follow-up x-rays because their orthopedists
are concerned about possibly having misjudged the stability of the fracture.When a number of follow-up x-rays were reviewed, however, all
the fractures that had initially been judged stable were found to have
healed correctly. Therefore, it is a waste of money to order follow-up
x-rays of ankle fracture initially judged stable.

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.
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.
C. X-rays of patients of many different orthopedists working in several
hospitals were reviewed.
D. The healing of ankle fractures that have been surgically repaired is
always checked by means of a follow-up x-ray.
E. Orthopedists routinely order follow-up x-rays for fractures of bone
other than ankle bones.

C. Correct answser

Using negation, we can see that if we negate C, the conclusion is significantly weakened.

Interesting question. be POE I agree w/ C

The given information:
- (P) patients with ankle fractures that do not require surgery are given follow up x-rays to double check
- (P) X-rays results reveal fractures healed correctly
- (C) it is a waste of $ to order follow up x-rays for ankles that were judged stable

A - exclude; compares general practitioners with orthopedists; not what the argument is based on
B - indicates information about an ankle injury where there is no fracture; out of scope;
D - indicates information about an ankle injury that has been surgically repaired; out of scope;
E - discusses what doctors do for other fractures; vague but doesn't seem to really strengthen the argument that it is a waste of $ to order follow up x-rays.
