I always have some problems with main point question
I got rid of B because I thought his work with the NAACP is about fight against racial/discriminatory segregation and not about civil right goals
I got rid of C because it is not "reinvestifation of his record as judge" that reveals its influence on current divergent political object
I have difficulties getting rid of A, and D. Would anyone tell me why they are wrong? Is A wrong because of the "certain" discriminatory laws. Is D wrong because the last sentence should change to "become accepted conventions in the field of public interest litigation"?
