A company's two divisions performed with remarkable consistency over the past three years: in each of those years, the pharmaceuticals division has accounted for roughly 20 percent of dollar sales and 40 percent of profits, and the chemicals division for the balance.
Which of the following can properly be inferred regarding the past three years from the statement above?
Total dollar sales for each of the company's divisions have remained roughly constant.
The pharmaceuticals division has faced stiffer competition in its markets than has the chemicals division.
The chemicals division has realized lower profits per dollar of sales than has the pharmaceuticals division.
The product mix offered by each of the company's divisions has remained unchanged.
Highly profitable products accounted for a higher percentage of the chemicals division's sales than of those of the pharmaceuticals division.
一个公司的两个部门在过去的三年表现得很互补：制药部门占据了20%的销售额和40%的利润。同时化学药物部门弥补了剩下的份额（ 80%的销售额和60%的利润）
must be true:
choice c, 化学部门在每一美金的销售额上实现的利润，要低于制药部门每一美金销售额实现的利润。
choice e, 高利润药物在化学部门占了更高的比重，比起制药部门。-> opposite to the context
互补是从哪得出来的? consistency是持续稳定的意思吧
