Aj previewed his speech about washington d. c. as follows: "today i'm going to discuss where some of the important landmarks in washington d. c. are located. i'll start with the washington monument, then talk about the lincoln memorial and finish with the vietnam veterans memorial wall. raj used a organizational pattern for his speech.

The organizational pattern used by Aj to previewed his speech about Washingtond.D.C. is the topical or categorical pattern.  His topic was about Washington D.C. and he talked about its landmarks such as Washington Monument,  Lincoln Memorial and Vietnam Veterans Memorial wall in logical order. 

the correct answer is: (1) affected by gerrymandering; (2) not affected by gerrymandering.

gerrymandering is known as a practice that intends to establish a some kind of political advantage for a particular party or group. to do this district boundaries are manipulated. the new resulting district is named a gerrymandering.

in other words, what gerrymandering does is to draw the boundaries of electoral districts trying to benefit the party who is doing it. sometimes, the party controlling the legislature will redraw it so they can maximize the number of districts they are likely to control.
