The wording of this summer assignment (Huck Finn) is very confusing. Its a summer assignment so I can't ask any teachers etc?

In 2-3 double-spaced, typed pages, list (the first few words, last few words, and page
number) of the passages, and write out a BRIEF explanation for each of the following
literary techniques used:
 character development (minimum of 3)
 plot/conflict development (minimum of 3)
 thematic development (minimum of 3)
 the use of humor (minimum of 3)

what does the (minimum of 3) mean? three passages?
If it's three passages, then does each get an explanation, or do all three get one explanation?
