People these days never really know how to be themselves. Our world is mostly made up of cheaters and copycats. Sometimes, it's very rare to come across a person who is original to themselves. People follow other people around, thus blindly conforming to groups
Keep in mind that a compound predicate has two or more verbs.
Based on that information alone, we can eliminate A and B. With C, this one seems like it could work, but it actually doesn't. The verb in that sentence is "enjoy", and in this case, "skiing" and "skateboarding" are nouns. (because they're the object of the predicate verb.) That leaves D as the answer!
Hope I helped! :)
tl;dr: The answer is D!
I can only provide one <span>anecdote since I don't have enough time.
'The past will let you go if you let go of the past.' Some of us have some memories we want to get out of our head, and some of us have memories we want to keep forever. Some people don't get to make that decision because they took too much time or they didn't get the chance to.
They didn't take life for granted. </span>
