Typing a at the beginning of a word will exclude that word when doing a search. question 1 options: ; (semi-colon) , (comma) - (hyphen) . (period)

Hyphen

- uses it like this in contexts to support a point or main idea
- a period would just put it down below the hyphen 
- most people do research like this anyway and always make a point by doing there research papers and story build mainly like this 

Ithink the answer is b. hope this .
