单选题 A As long as poor people, who in general are B colored , are in conflict with richer people, who in general are C lighter D skin , there"s going to be a constant racial conflict in the world.
【正确答案】 D
【答案解析】解析：skin一skinned。句意：只要那些主要由有色人种构成的穷人和一般由白人构成的富人之间的冲突不断，世界上就会有不断的种族冲突。原从句意为“富人都是浅色皮肤”，需用形容词作表语，因此需改为“是浅色皮肤的”lighter skinned。
