### HideShow timer Statistics

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

The total amount of plastic being manufactured has not increased. That means that recycling has increased. That means that less of plastic is thrown away. So the statement that "attempts to decrease the amount of plastic that people throw away in the garbage are failing" is wrong.

I don't agree with you on that one...

Let's take this fictitious situation:

Previously Now
Total garbage 100 200
(in units)

Plastic garbage 20 (20%) 42 (21%)
(in units)

Other garbage 80 (80%) 158 (79%)
(in units)

This situation is consistent with:

- The premise of the argument since the proportion of plastic is increasing (from 20% to 21%)
- The D answer since an increasing proportion of other garbage being recycled is equivalent to a decreasing of the proportion of other garbage (from 80% to 79%)

Though, the amount of plastic garbage is increasing (from 20 to 42 units) which confirms the conclusion of the argument instead of weakening it...

(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

Here is how I think through this question:

STEM AND QUESTION:
1. disposable plastics may not be the same as plastics
2. disp plastics increasing % of total trash which is NOT the same as amount, unless they tie it in by saying total amount increased or stayed the same. The Argument is flawed by design, but we don't care, because all we need to do is make this flawed argument even weaker. However, from here we know that either disp plastics increased in amount, or the rest of the trash decreased!
3. conclusion - attempts to decrease AMOUNT of ANY plastic thrown in garbage - fail (THIS IS STATEMENT IS ALL WE NEED TO WEAKEN)

A. harmfulness? Waste management disposing more in landfills (instead of incinerators)? Nothing mentions what the public throws away or anything else from our Conclusion - too much extra details, scope shift in this answer. this is definitely WRONG!
B. types of plastics- recyclable or not, nothing to do with the conclusion and no mention that amount of trash disposed by public is increased. WRONG
C. Completely irrelevant to the argument. If you are trying to make a leap between this answer and anything useful you would be adding YOUR OWN ASSUMPTIONS to the premise -definitely WRONG
D. If other trash is recycled more, than amount of trash would be reduced and plastics, without changing their amount, would become a higher percentage of the total. This damages the conclusion because it shows % can increase without amount changing, and the conclusion is all about increased amount of plastics. This could also be a weak answer if there is more than paper, glass, and metal cans that can affect the total trash, so its a MAYBE, but MOST PROBABLE SO FAR. Remember, they don't need a perfect answer, just the least bad one from the 5 listed.
E. This is playing on your attention to detail. Products with plastic packaging and amount of manufacturing have NOTHING to do with what is thrown out by consumers. IF you think they do, you are adding assumptions of your own. This can trick you if you are looking for the key words "percentage ... increasing and total amount... unchanged". But it is definitely wrong because it talks about a completely different topic.

CONCLUSION: Some answers are more wrong than others. The best thing you can do is look for flaws not in bigger meaning or at conceptual level but in the words themselves. I underline the key parts of stem and question in order to catch the right words to keep in mind. Each one of those questions can be solved on the details level without having to go through the religious reasons behind each answer. I hope this helps.

For me, this is a game of hide and seek. So I play it in reverse. First I go through with a fine comb eliminating answers that are wrong because of scope shift, wording, added assumptions, or large leaps that make you add your own assumption, or just anything that has nothing to do with the conclusion. Then, from the few left I look for the one that is least wrong. The right answer hides in the details, and the harder the question the more unnecessary details will be added to hide the right answer and confuse you.

D, as that weakens the argument, if less others are being processed, then proportion of plastic will go up even if amount stays the same.

For me,
this seems to be a poorly worded question/with equally poor answer choices!

What is the source ?

My explanation shows the approach that took me over the V40 barrier. It is much easier to answer any question when you take out misleading answers.

For me, this seems to be a poorly worded question/with equally poor answer choices!
I agree.

+1 D

Need to weaken the conclusion that attempt to reduce plastic waster has failed.

D states that other waste has become less thus making plastics stand out more but in fact nothing has changed

Looks like its D. Was confused between A and D but then, there are ways of more green disposal of plastic which could have been adopted.AND there can be several other arguments that may come against A.
D, on the other hand, shifts the attention to entirely different angle of viewing at the argument given. And if true...i guess this is the one that weakens the given statement most..
Cheers...!
