A recent research article published under the title An American Dream claims that the duration of REM sleep in adult Americans nowadays is significantly shorter than was the duration of REM sleep in adult Americans in the 1950s. In this, the research article's claim cannot be wrong because it compared the duration of REM sleep in 100 participants today to that of 100 participants of a similar study conducted in the 1950s, and the results clearly showed a decrease in the duration of REM sleep in each and every one of the participants.
Which of the following points to the most serious logical flaw in the writer's argument?
A. Dreaming is not only about the duration of REM sleep.
B. The argument fails to specify the exact duration of REM sleep in the 1950s and nowadays.
C. Modern day participants may have been chosen so that their results reflect the decrease suggested by the research.
D. The research does not refer to international statistics to show whether or not the decline has occured globally.
E. The title of the research does not properly reflect the results of the research.

We are concerned about what makes the claim wrong
A. Dreaming is not only about the duration of REM sleep.
Dreaming is irrelevant
B. The argument fails to specify the exact duration of REM sleep in the 1950s and nowadays.
passage mentions about relative REM sleep duration. We are not concerned about the absolute REM sleep duration
C. Modern day participants may have been chosen so that their results reflect the decrease suggested by the research.
This suggests that the sample wasn't representative, casting doubt on the outcome of the study
D. The research does not refer to international statistics to show whether or not the decline has occured globally.
The claim is for American adults, global stats are irrelevant
E. The title of the research does not properly reflect the results of the research.
We are concerned about the claim and not where it was published

A. Dreaming is not only about the duration of REM sleep. Eliminated This does not effect the conclusion in any way, as the conclusion is about duration of REM sleep.
B. The argument fails to specify the exact duration of REM sleep in the 1950s and nowadays. Eliminated As the exact duration does not invalidate the fact that the duration has decreased when compared to previous data.
C. Modern day participants may have been chosen so that their results reflect the decrease suggested by the research. Suitable as only 100 participants have been selected for study, there are chances of heavy selection bias in such studies and sample may have been molded to suit the desired conclusion.
D. The research does not refer to international statistics to show whether or not the decline has occurred globally. Eliminated The conclusion is concerned only with "American Dreamers"
E. The title of the research does not properly reflect the results of the research. Eliminated Out of context for the answer
