Technical Articles

by komal » Tue Mar 09, 2010 7:48 am
The increasing complexity of scientific inquiry has led to a proliferation of multiauthored technical articles. Reports of clinical trials involving patients from several hospitals are usually coauthored by physicians from each participating hospital. Likewise, physics papers reporting results from experiments using subsystems developed at various laboratories generally have authors from each laboratory.

If all of the statements above are true, which one of the following must be true?

(A) Clinical trials involving patients from several hospitals are never conducted solely by physicians from just one hospital.

(B) Most reports of clinical trials involving patients from several hospitals have multiple authors.

(C) When a technical article has multiple authors, they are usually from different institutions.

(D) Physics papers authored by researchers from multiple laboratories usually report results from experiments using subsystems developed at each laboratory.

(E) Most technical articles are authored solely by the researchers who conducted the experiments these articles report.

See explanations:

(A) Clinical trials involving patients from several hospitals are never conducted solely by physicians from just one hospital.
[nothing specified as such]

(B) Most reports of clinical trials involving patients from several hospitals have multiple authors.
[it's B: look out the word 'usually', that hints that Most of the cases reports of clinical trials involving patients from several hospitals have multiple authors.]

(C) When a technical article has multiple authors, they are usually from different institutions.
[nothing specified as such]

(D) Physics papers authored by researchers from multiple laboratories usually report results from experiments using subsystems developed at each laboratory.
[Altered meaning.. it should be 'Physics papers reporting' not 'Physics papers']

(E) Most technical articles are authored solely by the researchers who conducted the experiments these articles report.
[nothing specified as such]

Agreed that the word usually is an indicator that (B) Most reports of clinical trials involving patients from several hospitals have multiple authors. What about the use of the word Likewise, it does indicate a similarity. Like what ? Is it not that (C)a technical article has multiple authors, they are usually from different institutions just like (B). (C) cannot be ruled out offhand.
