Last year, all of the medical waste at County Hospital was sterilized by autoclaving, then shredded. This process generated a large quantity of unusable material that ended up in a landfill. In order to reduce its trash this year to half of last year’s total, the hospital has updated its waste removal practices. This year, it will autoclave all waste and then incinerate all non-plastic medical waste. This should decrease the number of tons of waste sent to the landfill by half.

Which of the following is required for the updated waste removal program to achieve its aim?

A. This year, the hospital will incinerate all possible materials. -This can be inferred from the argument. Its not an assumption.

B. The total quantity of medical waste generated at the hospital this year will be no greater than that generated last year. -Total may be equal or less than what it was last year, but the proportion of waste shredded can be larger than it was last year.

C. The waste shredded this year will weigh no more than the waste shredded last year -This is not exactly 100% correct, but it is best of the worst. It essentially says that the quantity of shredded waste sent to landfill this year is less than or EQUAL to the quantity of waste sent to landfill last year. "Equal" is not exactly making it a correct answer, however all other options are very irrelevant.

D. Medical waste generated by County Hospital will contain a larger proportion of non-plastic waste this year than it did last year. -It may contain a larger proportion of non-plastic waste but the amount of waste shredded can be greater than that was shredded last year.

E. Separating plastic from non-plastic waste will cost the hospital half of what it cost last year to send the waste to landfills. -We are not worried about the cost.

this question is easy, surely, the question has the common pattern in gmat, test takers should learn this.
"number of tons" = weight,
not quantity or proportion or costs.

The word 'ton' in the final sentence is very easy to miss. "This should decrease the number of tons of waste sent to the landfill by half. "

A) Too extreme.
B) Quantity can be the same but weight may be more thus negating the whole process.
C) Correct. Weight is same, hence the idea of incinerating all the non plastic waste will work.
D) Same as B
E) Cost is out of scope

Hi Karishma,

I have one question regarding Option C,

The waste shredded this year will weigh no more than the waste shredded last year

This need not be true. Say, weight of shredded last year be 100 tons, but total number of shredded items can be 100.
This year, total weight can be more than 100 tons, say 120 tons, but still total number of shredded items can be 80.

Question stem says, about number of items filling the landfill to be reduced to half, a item can weigh heavy can still occupy less space.

This is the exact reason, i rejected C. Can you please help

Thanks

Number of items shredded has no relevance since the waste is mentioned in terms of tonnage only.
Note: This should decrease the number of tons of waste sent to the landfill by half
