In 2000, a mere two dozen products accounted for half the increase in spending on prescription drugs, a phenomenon that is explained not just because of more expensive drugs but by the fact that doctors are writing many more prescriptions for higher-cost drugs.
A. a phenomenon that is explained not just because of more expensive drugs but by the fact that doctors are writing B. a phenomenon that is explained not just by the fact that drugs arebecoming more expensive but also by the fact that doctors are writing C. a phenomenon occurring not just because of drugs that are becoming more expensive but because of doctors having also written D. which occurred not just because drugs are becoming more expensive but doctors are also writing E. which occurred not just because of more expensive drugs but because doctors have also written
D不平行：not just because...but also (because)... C: but also要连在一起用，C项表达确实confusing， 两个原因是："rising drugs price" and "more prescriptions for higher-cost drugs", 而不是C项简单的"drugs and doctors"
In 2000, a mere two dozen products accounted for half the increase in spending on prescription drugs 这句话什么意思呢？麻烦谁帮我翻译下好吗？ 如果这是发生在2000年的，为什么后面的时态不用过去时？ 这道题我就是不理解以上两点，单看选项B确实是一个完美的结构。
