GWD-24-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.

答案C，原题逻辑是因为很多人做了X-ray发现没有问题，所以follow-up
x-rays
是浪费钱。C的意思就是很多医院都在review x-rays,难道这就能对原题形成强化吗？难以理解，请高人点拨 |
