C is the answer because by saying he has Thomas is specifying that it was the King all the wrong things.
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)
Answer:
Very important. Each paragraph should begin with a topic sentence setting out what will be discussed. The body should contain properly structured sentences (no fragments or runons) containing supporting details—examples, explanations, or events. The concluding sentence should indicate in some way that the topic is completed or hint at the topic of the following paragraph. The writing should be concise but meaningful using well chosen words and avoiding repetition (except for rhetorical effect). Avoid bland words and cliches, and look for verbs that convey two ideas (such as paced for walked nervously) and replace it and they with the names of things.
