(A) will soar to a level more than one-third higher than were those (B) will soar to a level more than one-third higher than that (C) would soar to a level more than one-third higher than it was (D) would soar to a level more than one-third higher than those (E) would soar to a level more than one-third higher than they were A. 复数those不能指代单数level，因此只能强制指代前句的复数主语emissions，那么，句子变成将 level与emissions相比较，比较对象不对等 B. 正确。 C. 主语应该使用will，而不是would D. 主语应该使用will，而不是would；复数those没有指代对象 E. 主语应该使用will，而不是would；复数they没有指代对象
