you have too sight the last name of the author and  the page number whether it is a quote or paraphrased. the only time you don't have to is if you include it in the sentence.
Example for when you don't have to cite in text:
On page 13 Martin says, "blah blah bah bluh bleh blah"   
... otherwise just put the citation in parentheses after the quote/paraphrase like so: (Martin,13)

Explanation:
The Great Depression was one of the worst economic catastrophes in American history and a major disaster of the modern era. It was harrowing to experience. People were starving, even in the land of plenty.  It triggered political upheavals in Europe that had devastating consequences. And it was so persistent that it only yielded to another global tragedy: the Second World War.
