### HideShow timer Statistics

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.

(A) Clinical trials involving patients from several hospitals are never conducted solely by physicians from just one hospital.
Clinical trials from several hospitals are usually co-authored. Never is too strong here.
(B) Most reports of clinical trials involving patients from several hospitals have multiple authors.
The text says that 'Clinical trials from several hospitals are usually co-athored'. Bingo, so most reports are co-authored.
(C) When a technical article has multiple authors, they are usually from different institutions.
Text does not mention.
(D) Physics papers authored by researchers from multiple laboratories usually report results from experiments using subsystems developed at each laboratory.
Relationship reversed. Just because the authors are from multiple laboratories doesn't mean that they mainly use sub-sustems from each laboratory.
(E) Most technical articles are authored solely by the researchers who conducted the experiments these articles report.
Multi-authored technical articles have increased lately, according to the text. But we know nothing about the ratio/proportion between single and multiauthored.

B. Says MOST. Isnt it extreme?

I like D.
Premise : Reports of clinical trials involving patients from several hospitals -> usually coauthored by physicians -> each participating hospital.
Likewise, physics papers reporting (experiments using subsystems developed at various laboratories) generally have authors from each laboratory.

Can anyone explain why D is wrong (if it is wrong) ?

Here's how I'd approach this one:

It's a Draw a Conclusion questions type, so only premises are given. The correct answer should not require any assumptions or logical leaps, no matter how probable they might be. The correct answer is likely to be a rephrase of one or more of the premises.

The argument can be diagrammed as follows
Increasing complexity --> More multi-author articles.

Example 1: Clinical trials: Patients from several hospitals --> authors USUALLY from those hospitals.

Example 2: Physics papers: Experiments using systems from various labs--> results GENERALLY reported by authors from those labs.

Now the choices, with key/limiting words emphasized
A. Clinical trials: Patients from several hospitals-->NEVER conducted by physicians from just one hospital. NEVER is too strong, this cannot be proven with the info given.

B. Clinical trianls: Patients from several hospitals --> MOST reporst have several authors. This is a very close restatement of Example 1.

C. Technical article: Multiple authors means various institutions are represented. Technical article too general, too much of a leap to turn the causation around. We are told that multiple institutions --> multiple authors, but you could have multiple authors from one institution, so you can't necessarily conclude that multiple authors -->multiple institutions.

D. Physics papers: Multiple authors from multiple labs -->experiments USUALLY used systems from multiple labs. Like (C), this turns the causation around. We are told that if multiple systems are used in the experiment, the report is written by authors at the lab that developed the system, but multiple authors might contribute to a paper for other reasons, too.

E. Technical articles: MOST authored only by researchers who conducted the experiments. The premise actually was that reports are authored by people who work at the institution where the experiment was done or the system developed, but that doesn't mean the authors were the people who actually ran the experiments.

It was close between B & D. This is how i eliminated D.

In stimulus,
E2: Physics papers: Experiments using systems from various labs --> Generally reported by authors from those labs.

AC: have authors from each laboratory. Each present a restriction which is not obvious from the "various".

Hope this help!

the studies, only who authors the reports. Thus, there is no proof for this
answer choice and it fails the Fact Test. Even if you mistook “conducted” for
“reported,” the answer choice is still incorrect because the stimulus indicates
that reports involving patients from several hospitals are usually coauthored
physicians from each hospital. Although “usually” could mean “always,” it
does not have to, and hence it is possible that a clinical trial could be
reported by physicians from just one hospital.
answer choice is a direct paraphrase of the second sentence. The second
sentence states, “Reports of clinical trials involving patients from several
hospitals are usually coauthored by physicians from each participating
hospital.” Answer choice (B) translates “usually” into “most,” and “coauthored
by physicians from each participating hospital” into “multiple authors.” Thus,
the answer choice passes the Fact Test and is correct. Answer choice (C):
This is a Shell Game answer choice. Although the stimulus says there has
been a proliferation of multi-authored technical articles, no comment is made
about the frequency of multi-authored technical articles. In the next sentence,
a frequency—“usually”—is given, but only for multi-authored clinical trial
reports. The test makers give you hard data about the clinical trial reports,
and then try to entice you into picking a broader answer involving technical
reports. Answer choice (C) shows how the Shell Game can occur in the
stimulus as well as in the answer choices. The stimulus of this problem
switches from “technical articles” to “reports of clinical trials.” Answer choice
(C) plays on that substitution. Answer choice (D): This is a Reverse answer
that contains a complex pair of reversed elements when matched against the
stimulus. Let us compare the stimulus and the answer choice, using italics to
indicate the reversed parts: The stimulus states, “physics papers reporting
results from experiments using subsystems developed at various laboratories
generally have authors from each laboratory.” Answer choice (D) states,
“Physics papers authored by researchers from multiple laboratories usually
report results from experiments using subsystems developed at each
laboratory.” The reversed pair has two notable features: 1. The numbers are
reversed—authors from each laboratory have become researchers (authors)
from multiple laboratories, and subsystems from various laboratories have
become subsystems from each laboratory. In a nutshell, the “various” and
“each” elements have been reversed in the sentences. 2. The pair also
reverses logical position within the argument, as the stimulus states that the
experiments generally have authors from each laboratory and the answer
choice states that the researchers usually report experiments from each
laboratory. Answer choice (E): As with answer choice (C), we do not know

Fact 1: The increasing complexity of scientific inquiry has led to a proliferation of multi-authored technical articles.
Fact 2: Reports of clinical trials involving patients from several hospitals are usually coauthored by physicians from each participating hospital.
Fact 3: Likewise, physics papers reporting results from experiments using subsystems developed at various laboratories generally have authors from each laboratory.

Must be true questions need to pass the Fact Test. Hence Test each choice against the Facts is the stimulus

(A) Clinical trials involving patients from several hospitals are never conducted solely by physicians from just one hospital. - Fact 2 states usually coauthored by physicians from each participating hospital. Besides this option is too extreme (Never), it is possible that a clinical trial could have been reported by only 1 hospital (Stimulus uses the word Usually indicating such a possibility).

(B) Most reports of clinical trials involving patients from several hospitals have multiple authors.- Correct. Usually can be replaced with Most can still indicate the same.

(C) When a technical article has multiple authors, they are usually from different institutions. - This is an assumption based on the arrived at based on Fact 2, however this may not be true and since this question is on Must be true this fails the fact test

(D) Physics papers authored by researchers from multiple laboratories usually report results from experiments using subsystems developed at each laboratory- This changes the order of words in Fact 3 and thus changes the meaning (Misplaced Modifiers)

Fact 3 states "Physics papers reporting results from experiments using subsystems developed at various laboratories generally have authors from each laboratory. ("

E) Most technical articles are authored solely by the researchers who conducted the experiments these articles report.-Not explicitly mentioned hence not correct
