What does test anxiety really look like on the GMAT? For many test takers, it does not look like a panic attack. Instead, it shows up as brain fog, rereading, negative comparisons, mental noise....

I came across this question in Powerscore CR bible.
“When temperatures drop just below freezing, the plant pathogen Pseudomonas syringae produces certain proteins that force ice to form on the surface of a plant. The damage caused by the freezing process releases plant nutrients that are then available to the Pseudomonas syringae bacteria. Although this fruit grove contains Pseudomonas syringae bacteria, temperatures have not dropped below freezing at any point during the last 30 days, so there should be no concern over Pseudomonas syringae-related damage during that period.”
The book says that there is an error of "Mistaken Negation".
In my opinion, "Temperature dropping below freezing point" is the necessary condition to "cause Pseudomonas syringae-related damage".
So, isn't the author's conclusion correct?
Even if the conclusion isn't correct, shouldn't the correct AO be something like "author fails to consider other ways Pseudomonas syringae can cause damage to a plant"?

The passage doesn't support that conclusion. It indicates that "when temperatures drop just below freezing," Pseudomonas syringae damages plants. However, it does not say that, when temperatures do not drop below freezing, Pseudomonas syringae does not damage plants.
Quote:
No, because, even though "temperatures have not dropped below freezing at any point during the last 30 days," there still could have been occurrences of "Pseudomonas syringae-related damage during that period.”
Quote:
That description of the issue would work too. At the same time, while I'm not 100 percent sure what "mistaken negation" means in this context, but that description doesn't seem out of line.
