Answer 1

first 

D. We learned that the president elect will be here tomorrow for a brief speech.

then

B. Add three-quarters of a cup of raisins.

Answer 2

First sentence:

Option D) "We learned that the president elect will be here tomorrow for a brief speech." has a punctuation error. The mistake in this sentence is the use of "president elect" without a hyphen between those two words. The correct writing is "president-elect".

Second Sentence:

Option B) "Add three-quarters of a cup of raisins." has a punctuation error since the phrase "three-quarters" does not include a hyphen between the words three and quarters. In this case, the phrase "three quarters" is not an adjective and should not be hyphenated.

There is a difference with option C) for example since the phrase "one-quarter" is hyphenated because it is modifying the noun "cup".
