im sorry i am so late to this, cant believe nobody has answered this easy question! probably katniss, because of all the people she inspired. in the beginning of the books she was seen as a weak looking girl who volunteered for her sister. but in the second and third books, you can see how much she is looked up to and idolized.
The answer you are looking for is A, member. The other 3 all have to do with being mindful! While a member just refers to a person. Not to mention there is no "or" in member!
Hope this helps!
The answer is (A) It would focus more on the social implications of the racial conflict.
Sorry if I'm a little late!!
