You didn't italize or mark the phrase, but I see one good candidate:
"The circus animal trainer" is in a way another name given to Mervin, a kind of "renaming" him: this is called an appositive phrase, so if this was the phrase appositive phrase is the answer! (also, I don't see the other phrases here).
I believe the correct answer is: D. The author humanizes the
prion with playful language by saying "[i]f it manages to burrow into a
corner."
In this excerpt from "Mad Cow, Furious Farmer”, the example
in which the author keepings a lively tone even while discussing a disease is:
"[i]f it manages to burrow into a corner."
As opposed to the terminology author uses (such as: bovine
spongiform encephalopathy (BSE)), the informal language of more commonly
understandable comparison gives the lively tone to this excerpt, even though he
is addressing the serious disease. Other example of this would be: "a
little bit squishy and maybe a little bit sticky".
while the race goes on obstacles are set up so the fewest boats possible can get through so the race is more high stakes.
The adjective would be "that I would" because it is the clause to the adjective.
