Costly X-rays often not needed, the OT rules were developed to aid in a doctor’s decision as to whether a patient with foot pain should be offered an X-ray, since only 5% of patients before the rules actually had fractures when X-rayed.

Can any one explain me the usage of ,+since in option B is correct?I believe in two IC can be placed with ; or they can be joined with but,and,yet,for,so.

but, and, yet, so can clearly not be used. For can be used as a possible conjunction. Between since and for, since is clearly more apt.

IMO C but OA is B. Can ne1 tell why not C?

Is it because the rule developed because only 5% patients had fracture before the rule and not that it is costly?

What is the difference between B and C ??

B. The OT rules were developed to aid in a doctor’s decision as to whether a patient with foot pain should be offered an X-ray, since only 5% of patients before the rules’ development actually had fractures when X-rayed, and these X-rays were costly and often not needed.
C. Since only 5% of patients before the rules’ development actually had fractures when X-rayed, and these X-rays were costly and often not needed, the OT rules were developed to aid in a doctor’s decision as to whether a patient with foot pain should be offered an X-ray.



B. The OT rules were developed to aid in a doctor’s decision as to whether a patient with foot pain should be offered an X-ray,
C. the OT rules were developed to aid in a doctor’s decision as to whether a patient with foot pain should be offered an X-ray.

B. since only 5% of patients before the rules’ development actually had fractures when X-rayed, and these X-rays were costly and often not needed.
C. Since only 5% of patients before the rules’ development actually had fractures when X-rayed, and these X-rays were costly and often not needed,

Not a single word difference found in these two choices just subordinate clause is moved in front in C.

The only difference between B and C is that of a subtle word order problem. In B, the main clause introduces the OT rules first and then follows it up with the rules’ development in the subordinate clause in the second part. Similarly, the X-rays have been introduced properly in the first part and then are anteceded by the pronoun ‘these’ in the latter part.

But in the case of C, the subordinate clause that is in the first part of the sentence talks of the rules’ development, even before, the term has been properly introduced; the actual introduction comes in the second part in the main clause. So also, C uses the pronoun ‘these’ in the first part, and uses the referred noun ‘x-rays’ in the latter part as postcedent rather than as antecedent.

C may technically be ok but still is considered inferior.
