标题: 请教og 81

In 1973 mortagage payments represented twenty-one percent of an average thirty-year-old male's income; and forty-four percent in 1984.

(B) income; in 1984 the figure was forty-four percent

(C)income, and in 1984 fourty-four percent

答案（B）是猜对了，但是（C）错在什么地方呢？og说是To estanlish the cleares comparison between circumstances in 1973 and those in 1984, a separate clause is needed to describe each year.难道(C)只是错在不是单独的句子？如果把（C）看成是省略表达，（C）有什么错误吗？

谢谢

and在这里显然是连接两个句子(因为and前有逗号且后部是介词状语开头)，所以B表达比C表达好；而且C的表达不够清楚，换言之，省略了太多的东西反倒使句子的意思不够明确，44 percent后有其他的可能。
