Answer:
How does Elena seem to feel about Eugene according to her mother
Explanation:
switch the sentence to sound like a question instead of an answer.
D) Subject is the element necessary to complete the sentence above.
You already have a predicate (drives), so you don't need that, or a subordinate/independent clause. What you do need is a subject. For example:
<em>Mercedes </em>drives like no other car.
The second statement is the most accurate.
Hope this helps!
