Many
people suffer an allergic reaction to sulfites, including those that are
commonly added to wine as preservatives. 
However, since there are several winemakers producing wine to which no
sulfites are added, those who would like to drink wine but are allergic to
sulfites can drink these wines without risking an allergic reaction to
sulfites.

Which
of the following, if true, most seriously weakens the argument?

A. Sulfites occur naturally in most
wine.  

B.
The sulfites that can produce an allergic reaction are also commonly found in
beverages other than wine.

C.
Wines without added sulfites tend to be at least moderately expensive.

D. Apart from sulfites, there are
other substances commonly present in wine that can trigger allergic reactions.  无关
            

E.
Wine without added sulfites sometimes becomes undrinkable even before the wine
is sold to consumers.

X:  In order to reduce the amount of plastic in
landfills, legislatures should impose a ban on the use of plastics for
packaging goods.

Y:  Impossible! 
Plastic packaging is necessary for public safety.  Consumers will lose all of the safety
features that plastic offers, chiefly tamper-resistant closures and
shatterproof bottles.

Which
of the following best describes the weak point in Y's response to X's proposal?

A.
Y ignores the possibility that packaging goods in materials other than plastic
might provide the same safety features that packaging in plastic offers.

B.
The economic disadvantages of using plastics as a means of packaging goods are
not taken into consideration.

C. Y attempts to shift the blame for
the large amount of plastic in landfills from the users of plastic packaging to
the legislators.

D.
Y does not consider the concern of some manufacturers that safety features
spoil package appearances.

E.
Y wrongly assumes that X defends the interests of the manufacturers rather than
the interests of the consumers.

这个题目不是强调重点在“the weak point in Y's response to X's proposal”么？

A只涉及Y的proposal, 对于X根本就没有提及啊，这个叫 response？
