In the country of Laurelia, legal restrictions on the sale
of lock-picking equipment were relaxed ten years ago,
and since then Laurelia's burglary rate has risen dramat-
ically. Hence, since legally purchased lock-picking
equipment was used in most burglaries, reintroducing
strict limits on the sale of this equipment would help to
reduce Laurelia's burglary rate.

Which of the following, if true, gives the strongest support to the argument?
(A) Laurelia's overall crime rate has risen dramatically
over the last ten years.
(B) There is wide popular support in Laurelia for the
reintroduction of strict limits on the sale of lock-
picking equipment.
(C) The reintroduction of strict limits on the sale of
lock-picking equipment in Laurelia would not
prevent legitimate use of this equipment by
police and other public safety officials.
(D) Most lock-picking equipment used in Laurelia is
fragile and usually breaks irreparably within a
few years of purchase.
    (E) The introduction five years ago of harsher punish-
ments for people convicted of burglary had little
effect on Laurelia's burglary rate.
答案为D,但我认为应该是E

    Many people acquire software programs for their
home computers by illegally copying those programs
rather than purchasing them. People who own home
computers must be making, on average, fewer illegal
copies of software programs than before, however,
since the average number of software programs that
people purchase to use on their home computers has
increased substantially over the past five years.

Which of the following, if true, most strengthens the
argument?
(A) The number of home computers in use has
increased substantially over the past five years.
(B) Five years ago, about half of the software pro-
grams used on home computers had been
illegally copied rather than purchased.
(D) Few people who prefer to copy computer
software programs illegally cannot copy the
software programs they want because they
have no acquaintances who have those
software programs.
(E) On average, people with home computers have
the same number of software programs today as
          people with home computers did five years ago.
答案为E，但是问题里strengthens the argument到底是针对第一句话还是后面的观点。

No.1
lock-picking equipment     cause    burglary rate increase,

then if lock-picking equipment  decrease in the future, as D says,  burglary increase rate will  at least  be reduced to some extent.

E,  "The introduction five years ago of harsher punish-ment" is a new conception, and if little effect,then will still little effect in the future, so `won't help decrease  burglary rate.
  

No.2

through passage,  we can get that
the number of software program  average home has to use = illegally copying to use + purchase to use

as E says ,On average,  ....have the same number of software programs  ....

then  if purchasing number increase, illegally copying number decrease.

thus E strenthen the argument i.e.,the whole passge.
