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)
We need a story or the rest of the information to figure out the answer
Let this be so.
His means of death, his obscure burial—
No trophy, sword, nor hatchment o'er his bones,
No noble rite nor formal ostentation,
Cry to be heard, as 'twere from heaven to earth,
That I must call't in question.
The answer is c, romp. the others dont make sense
