lz,答案是什么？？答案是e吧。。。怎么可能是a呢？你看错了吧。。。
原文：鱼的销量增加了4.5%,家禽销量增加9%，人口数量增加6%。
a,明显是错误答案，原文信息就那么多，a中说的是批发商的利润问题，肯定是无关的，因为原为没有任何信息涉及到利润问题。比如说，鱼的成本低于家禽的成本3倍，那么即使家禽卖的比鱼多，利润还是比鱼低啊。。。。

Take the population to be 100
Fish - 100
and
Poultry consumption also as 100

So after Increase
Population in 1989 - 106
Fish- 104.5
and
poultry 109

So per capita for fish consumption in 1980 was 100/100 = 1
in
1989 it becomes 104.5/106 <1

So fish consumption decreases.
