Good one !

Just used on of the techniques stated in the CR Bible --> Show that the data used to make the casual statement is accurate, or eliminate possible problems with the data --> (C) Illustrates the mentioned technique.

A) Doctors who are general practitioners rather than orthopedists are less likely than orthopedists to judge the stability of an ankle fracture correctly --> wrong comparison, absolutely irrelevant
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 --> Injury is not = fraction
C) X-rays of patients of many different orthopedists working in several hospitals were reviewed -->CORRECT. For the reason stated above
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.

This post was
BOOKMARKED
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.

Took me a while to understand why answer choice A is incorrect. I am still not wholly convinced that C could be a correct answer choice, since several isn't sufficient to indicate representativeness. Tricky question.

A: talks about other doctors, why do they judge it. irrelevant
B: talks about other ankle injuries. irrelevant
C: means survey was big enough. let's negate=>weaks. let's keep this one
D: surgically repared..irrelevant
E: other than ankle bones. one word off-common trap.

"C" shows that the sample of x-ray data examined was probably sufficiently representative of cases of ankle fracture judged to be stable by orthopedists.

B is the answer as we have to look into the best choice .
C does not make any sense as x-rays being reviewed is not solving our problem of whether follow up x rays of ankle fractures is a waste of money or not .

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.

To strengthen the argument, there was a need of an option confirming that in stable ankle fractures there indeed is no need for a follow up x-ray.
Since, we do not have any option confirming the same, option C is the best choice because it claims that a large number of reports from various doctors were reviewed, thus increasing the validity of the survey/review, consequently strengthening the argument.

Option E looks at least a little convincing but it again fails to provide a legitimate reason for believing that follow up x-ray is not needed. It claims that Orthopedists routinely order follow-up x-rays which one might believe is done only to increase the customers bill (and serves no other purpose), thus strengthening the argument, but it confirms nothing.

Hope my reasoning makes sense.

Using POE, test takers can still choose C.
The pattern in C is rare. C basically says results of X-rays ordered by other orthopedists are same.

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.

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.
