To allay fears whether they had misjudged the fractures even in patients with stable femur injuries, and thus do not require surgery, orthopedic surgeons often prescribe follow-up x-rays. Nevertheless, when a number of follow-up x-rays were reviewed, all the fractures that were initially screened as stable were found to have healed correctly. Thus ordering follow-up x-rays of femur fractures initially judged to be stable, is a drain on financial resources.
Which of the following, if true, most strengthens the argument?

A. X-rays of patients of several orthopedic surgeons working in numerous hospitals were reviewed.
B. General practitioners are less likely than orthopedic surgeons to judge the stability of a femur fracture correctly.
C. X-Rays of many femur injuries for which an initial x-ray is ordered, reveal no signs of any fracture of the femur.
D. Healing of femur fractures that have been surgically repaired is always assessed by means of a follow-up x-ray.
E. Orthopedic surgeons routinely order follow-up x-rays for fractures of bone other than femur bones.

Timed my response 2:39 and IMO A .

Though does not add anything new I did not find a better option.
[spoiler]B weakens
C weakens
D nothing about its relation with stable fracture.
E nothing about its relation with femur fracture. [/spoiler]

I think in 2 mins you can reason only so much.

The conclusion can be prephrased as follows : follow-up xrays are a waste of money.

A. X-rays of patients of several orthopedic surgeons working in numerous hospitals were reviewed.
Correct : This strengthens the argument by implying that follow-up xrays are not a drain on financial resources in a particular hospital but in many hospitals.

B. General practitioners are less likely than orthopedic surgeons to judge the stability of a femur fracture correctly.
Incorrect : If GPs cant judge the stability of femur fracture correctly then follow-up xrays might become a necessity and hence it might not really be drain on financial resources. This answer choice clearly weakens the argument by implying that follow-up xrays are not waste of money after all.

C. X-Rays of many femur injuries for which an initial x-ray is ordered, reveal no signs of any fracture of the femur.
Incorrect : If initial xray does not show any sign of fracture then follow-up xray might become a necessity and not waste of financial resources. Weakens the argument. Eliminated.

D. Healing of femur fractures that have been surgically repaired is always assessed by means of a follow-up x-ray.
Incorrect : Another weakener. Implies that follow-up xray is necessary. Eliminated.

E. Orthopedic surgeons routinely order follow-up x-rays for fractures of bone other than femur bones.
Incorrect : Fractures of bone other than femur bones is irrelevant here.

Let's figure out the conclusion : There is a financial loss by conducting the X-Ray test for the second time .

Why it is being done?? Doctors are not confident on their diagnosis. Look for the term "To allay fears ......".

C strengthens the claim made by the author that "doctors are fooling around the people by asking to go for second X -Rayjust to cross check their diagnosis & allay their fears of misjudgment ....by stating that, "Even in the first time of X-ray of the Femur injry, NO fracture is observed in many cases.".

While reading these kind of argments, assumes "A author" is making a claim against the doctor. and so our Option shuld strengthen the authors thought process.

I am not very good with explaining stuff but here is my 2 cents.

Conclusion: Ordering follow-up x-rays ....drain on financial resources.

We are asked to strengthen the argument. The only option that strengthens the conclusion is C. IF THE INITIAL XRAY DOES NOT SHOW A FRACTURE WHAT IS THE POINT OF GOING FOR A FOLLOW UP X RAY?? The only reason for a follow up X ray would be if you have a fracture in the first place. Therefore follow up X ray is only a drain on finances. Does it make sense?

Answer C seems to be logical one out of other answer choices
