Ultimately, I think Dosh is convincing to her audience, but the weaknesses outweigh the strengths.

Times 8 July 2016: A1. Print. This newspaper article talks about a university in California, purposely denying in-state students admission and favoring out-of-state students because they have to pay more. The article states this, in one way, by saying a student who family’s ties with the school dates back over 50 years and a lot of donations.

structure triggers N-to-D movement. I argue that proper names in Hijazi Arabic do not move to the head of D.

Comparing Two Articles on Teen Binge Drinking The article How to Manage Teen Drinking (the smart way), written by Jeffery Kluger and the article Getting Stupid, written by Bernie Wuethrich are both articles about teenage binge drinking.

Persuasive Articles on Gun Control Persuading an audience can be done in several different fashions, one of which is Hugh Rank’s Model of Persuasion. Rank’s model states that two major strategies are used to achieve the particular goal of persuasion. These strategies are nicely set into two main schemas; the first method is to exaggerate an aspect of something, known as “intensify.” While the second is to discredit it, which is referred to as “downplay.” Al Franken, Jeffrey Snyder, Harlan Ellison
still have that same picture/focal point to a degree. Specifically, the repetition of size (170x142pixels), color (greyscale), and angle variance in the graphics create a complimenting montage. Each of the repetitious graphics also lead way into the article they represent. A repetitious feature is also utilized in the navigation bar above the graphics. A mouse rollover displays a description of each topic area. The text appears on a white-on-black contrast in the upper right corner, again leading the
