You dont need to do number 1, 2, and 3. please fine the answer and do citation and reference. 

Download the Exercise 4 file, open it in Word, and answer the questions (10 points each correct answer, with deductions for style guide violations). Cite your sources as required by the English 202 Style Guide (2points each), and add a complete reference listing for each unique source in the References section at the end of the document (2points each).  

Because some students get confused about what date to use for a source when there is no publication date shown (often the case for online sources), here is an example that shows you what to do:

• You are researching John Millar Carroll, who, ironically, is mentioned in the exercise file. (Imagine the coincidence!) 
• Not having studied technical communication extensively, you are unlikely to revere John in the same fawning manner as do we who value science as a basis for writing and editing decisions. You Google “John MillarCarroll,” and one of the first results is http://ist.psu.edu/directory/faculty/jmc56, a page in the Pennsylvania State University, College of Information and Sciences Technology, faculty directory. 
• Not wanting to write “Pennsylvania State University” in the citation, you shorten the citation to say (Penn State Year). 
• But what year do you use? To be technically precise, you scroll down the page to the page footer and see that the page was copyrighted in 2016. Accordingly, the citation becomes (Penn State 2016). (If there were no copyright date shown, you would have used the year you accessed the page, which is 2016.)
• In the references section of your document, you provide the full source listing, which consists of “Name. Year. Article Title. Publisher. Web address and access date.” You end up with something like “Penn State. 2016. John Carroll. Pennsylvania State University. Available at http://ist.psu.edu/directory/jmc56.” (Notice the separators between items are periods–not commas or semicolons. It is a small thing, but small details matter.)

As a general rule, place the citation in the topic sentence of the paragraph in which you first mention the source. The reader will naturally assume that the supporting sentences also derive from the same source, so you do not need to cite the source repeatedly for each statement unless you switch to a difference source. As long as it is clear that you are still discussing the same source, you can continue the discussion into successive paragraphs without adding in-text citations.
