On turning 65 years old, everyone living in the town of Malton becomes eligible to receive a card that guarantees discounts on most goods and services sold in the town. Census records for 1990 show that 2450 inhabitants of Malton turned 64 in that year. Yet, in 1991 over 3000 people applied for and properly recerved discount cards. So clearly some of Malton's population growth between 1990 and 1992 must be attributable to migration into the city by people in their mid-60's.
Which of the following is an assumption on which the argument depends?
A. The town of Malton has no complete census records for 1991.
B. The overall size of the population of Malton grew by over 500 during 1990.
C. Fewer people applied for and received discount cards in 1991 and did so in 1992.
D. Among the people 65 years old or older who moved into Malton in 1991, there was no one who did not apply for a discount card.
E. In general, people who applied for and received discount cards in 1991 first became eligible to do so in that year

答案是E ，怎么解释呢？是不是指，这些超出来的人有可能是以前就可以申请，但是那时候他们没有申请，恰好在1991年的时候想到要申请了呢？

是说那些1991年申请的人，都是在1991年才刚刚一有资格（刚刚到65岁就来了）就来申请的。eligible对应第一句话。如果这个选项取非的话，那么很可能很多65岁以上的老人（比如很多67，68岁的）本来早就有资格申请了一直没申请，都集中到1991年来申请而已，这样的话argument就不成立了。
