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!
C. Tragicomedy. Good Luck!
Over exaggerated
In the context of this passage, which is talking about how Facebook is attempting to cut down on incorrect, fake, or 'sensationalized' news, the word clearly means news that is not true or over exaggerated in a way that makes it 'click bait'-something that isn't clear, objective content.
