Answer and Explanation:
<u>What functions as a subject is not really the relative clause, but the relative pronoun - "that".</u> Relative pronouns can act as subjects or objects in the clause they introduce. Let's compare:
1. I am the only person who saw Erica.
2. I am the only person who Erica saw and recognized.
Notice that in sentence 1, "who" is the subject of the clause "saw Erica". However, in sentence 2, "who" is the object. The subject of the verb "saw" now is "Erica".
<u>The same happens in the clause "that was hurt before". The relative pronoun "that" - which is substituting the noun "ankle" - is the subject of the clause "was hurt before". Therefore, we can say its noun function is the subject.</u>
A. Yesterday, Leo had a __more difficult__ time sleeping than today.
B. is incorrect because it is incorrect to say one has "a difficultly time" doing anything; you have "a difficult time" doing something.
C. is incorrect because you can not say "most" when comparing something to something else; you can either say "It was the MOST difficult" or "It was MORE difficult than that."
Most people would probably say good because you would be filled with energy and youth forever but on the downside you'd also miss out on a lot of things adults get to do.
I would personally say bad because instead of being stuck in school or having to listen to your parents you could find your dream job, spend time with friends, travel, etc. You can't get a job as a child until you're 16 but you are still under your parents control. So I think that it would be bad.
