How you use a dictionary?

Question

A. find the history, date first used, and meaning of word

B. find the words you need to express your idea

C. create study guides

D. organize your limits

Answer 1

Well it depends on if you're propping up a table, beating a child, or rolling blunts.  

Answer 2

Definitely will be B

Answer 3

Well, I think it's a toss-up between A and B.  I would say A, though.

A: dictionaries do give you the history (etymology) and meaning of words.

B sounds like it could actually be describing a Thesaurus.
