Mary is working on a persuasive argument paper titled "why voters should speak out against recent budget cuts in education." which two of these sources should she refer to while researching? a. a wikipedia entry titled "budget cuts in education" b. a university student's blog post on the budget cuts c. an article in newsweek describing the budget cuts d. the white house website’s entry on the budget cuts

C. An article in Newsweek describing the budget cuts.

D. White House's entry on the budget cuts.

Explanation:

Mary should consider "Newsweek's article" to strengthen her point and point out the reasons leading to the budget cuts in Education and its consequences. This would assist Mary to substantiate her points and convey it more emphatically.

The White House website's entry on the budget cuts would provide authenticity to her claims and assist her in relating to it with more credibility. This would also help her present the comparison and contrast among the previous budget cuts in Education and its impact that would bring out the flaws of the Government on the surface.  

Thus, both the two arguments would aid Mary in persuading the readers about the "budget cuts in education" and compel them to think and take necessary actions like a protest or anything against this.
