7. 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 2,
450 inhabitants of Malton turned 64 in that year. Yet .
in 1991 over 3,000 people applied for and properly
received 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 than 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
答案选D，可以我觉得E也对啊

可是我觉得D和E都是对得。D的话逻辑潜台词是：如果移民没有去领那个卡片的话，3000的增长后的数字可能是别的原因引起的，比如说当地的老战士回乡啊什么的（我自己Y的），所以是别的原因导致了人口的增长

如果D把1991改成1990. 还说得通.
否则D是不正确的.
E的话,一定是无关项了.
