D is a chronological event. The War Memorial was created where, how and maybe why. The maybe why is only about why Washington was chosen.
B again is recounting exactly how the peace was brought about in korea in the 1950s. It's not a positional paper.
A is not a position although it could be made into one. This question is a bit ambiguous and you are forced to choose between A and C. I would pick C because it is a position. No matter what else is relayed, the thing you must determine is that the Dental Association has a position: prevention.
A cannot be so easily dealt with. The problem is that it has a position, but it looks like it does not have any kind of resolution. It's intent is to show that antibiotics have an effect on the food chain. If it said a "good" effect or a "bad" effect, it would be a shoo in.
Answer C <<<<< But don't be surprised if it is A nevertheless.
Answer:
living in that time area of time
The government shutdown happened because President Trump wanted the Democrats to help fund the build of the wall, but the Democrats would not help support the wall that President Trump wants to build.
It's either A or D, I'm not sure about the comma? Definitely not B or C though
