Answer:
Trailers and essay introductions can be very, very similar. Essay introductions just give a very brief overview of what the essay will be about, just like how trailers give a little insight as to what the movie will be about. Neither essay introductions nor movie trailers give direct facts and information about either the essay topic or whole plot of the movie. The purpose it to mainly just "hook" the reader/viewer and make them want to either read the essay or watch the movie just based on the introduction or trailer.
Hope this helps.
Parameters are basically boundaries that are a rough outline of what you re expected to do, and the context clues used in the sentence are the words straight after the word parameters, "such as". That shows that the next words are synonyms of the preformentioned word.
Personally, number 3 because it sounds like it should have an exclamation mark.
I believe the answer is A, I had this same question on a test last year, and I'm pretty sure that's the answer.
