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....

Yes but make a wholesome call - not just based on pronoun ambiguity. If gmat has to muddy the correct answer - it will make it unattractive - Not the girl in the baywatch
If this sentence is in CR then I will assume that "it" is referring to extraterrestrial life.
noboru
The sentence is part of a CR passage, and when I saw it, I thought: "mmm...if this were a SC, there would be ambiguity??" Any more thoughts? Thanks,
to clarify, your sentence really doesn't make sense unless it [your sentence] is corrected by either the following:
This machine, searching for extraterrestrial life, will not find it.
In this example, i made the present participle + prepositional phrase modifier (searching for ET life) a nonessential (nonrestrictive) modifer. To do this, i need to specific the machine with the word This. [Note also that searching is NOT a gerund in this example; searching is serving as an adjective (present participle to be exact) that modifies machine.]
Or, you can correct the sentence by removing the comma:
A machine searching for extraterrestrial life will not find it.
It can be referred to machine or to life... ask the question: does it make sense to say, a machine will not find this machine? sounds quite funny, but still, it can be ambiguous even if it's quite obvious that the it should refer to life.
hope that helps
