问题 (It can be argued) that the problems, even something (as fundamental as) the (ever-increased) world population, (have been) caused by technological advance.
选项 A、It can be argued
B、as fundamental as
C、ever-increased
D、have been caused
答案C改为ever-increasing
解析 现在分词通常用来表示主动，而过去分词则表示被动。population与increase间是主动关系，所以应改为ever-increasing。
