Critical Reasoning

Waste management companies, which collect waste
for disposal in landfills and incineration plants,
report that disposable plastics make up an
ever-increasing percentage of the waste they handle.
It is clear that attempts to decrease the amount of
plastic that people throw away in the garbage are
failing.
Which one of the following, if true, most seriously
weakens the argument?
(A) Because plastics create harmful pollutants
when burned, an increasing percentage of
the plastics handled by waste management
companies are being disposed of in landfills.
(B) Although many plastics are recyclable, most of
the plastics disposed of by waste
management companies are not.
(C) People are more likely to save and reuse
plastic containers than containers made of
heavier materials like glass or metal.
(D) An increasing proportion of the paper, glass,
and metal cans that waste management
companies used to handle is now being
recycled.
(E) While the percentage of products using plastic
packaging is increasing, the total amount of
plastic being manufactured has remained
unchanged.
