The answer is C. Self expression
I just took the test.
Allen would need to re-sign the forms
In sentence 1, the word resign means to quit or give up your position. This word does not use a hyphen. In sentence 3 and 4 recover means to get or come back. In sentence 3, Bridget will get back the flyer, and in sentence 4 her body will also come back from whatever illness or injury it sustained. Sentence 2 uses the prefix re to show that Allen needs to sign the forms again.
The answer is the 2nd sentence, "John though his sophistication would win the love of Ellen."
Here's why:
abstract noun: a noun denoting an idea, quality, or state rather than a concrete object.
Sentence 1: the noun is "box", a concrete object.
Sentence 2: the noun is "sophistication", which is a quality, not a concrete object.
Sentence 3: the noun is "car", which is a concrete object.
Sentence 4: the noun is "mirror", a concrete object.
