An ecology magazine regularly publishes articles on tree diseases. This year, the number of articles on Ophiostoma ulmi, the fungus that causes Dutch elm disease, is significantly smaller than the number of such articles that appeared last year. Clearly, fewer researchers studied Ophiostoma ulmi this year than did so last year.
Which of the following, if true, weakens the above conclusion?
A. Many researchers publishing articles are currently studying Stegophora ulmeay a fungus that causes elm leaf spot.
B. Since its introduction, Dutch elm disease has killed half of the elm trees in North America.
C. Research on Dutch elm disease that focuses on prevention receives more funding than research that focuses on finding a cure.
D. A new strain of the fungus Rhytisma acerinum infested maple trees at an unprecedented rate this year.
E. All articles go through at least a one-year review process before publication.

A. Many researchers publishing articles are currently studying Stegophora ulmeay a fungus that causes elm leaf spot.
Irrelevant. This statement provides information on researchers studying the fungus Stegophora ulmeay, while the passage is about Ophiostoma ulmi.
B. Since its introduction, Dutch elm disease has killed half of the elm trees in North America.
No direct information is provided regarding the relationship between the number of elm trees and the number of researchers studying Ophiostoma ulmi. Perhaps this makes it more difficult for researchers to study the fungus, and thus strengthens the conclusion.
C. Research on Dutch elm disease that focuses on prevention receives more funding than research that focuses on finding a cure.
This is irrelevant. While one focus may be more funded than the other, they both focus on Ophiostoma ulmi and therefore if anyone shifted from one focus to the other, then the number of researchers would still be the same.
D. A new strain of the fungus Rhytisma acerinum infested maple trees at an unprecedented rate this year.
This could result in more researchers wanting to study this, thus leaving behind any Ophiostoma ulmi research. Regardless, nothing about this statement will weaken the argument.
E. All articles go through at least a one-year review process before publication.
This directly tackles the authors substantiation for the conclusion. The author says that as there are no publications on the fungus, then there must be less researchers studying it. However, if it takes one-year just to review the process before publication, then it is impossible for the author to come to the conlusion that he/she has.

How is the answer E?
Suppose there is a 1 year review process before publication but it hasn’t been mentioned that it has been introduced recently. If the review process was always there then it won’t matter right ?
