Hi Karishma
Option C states that "the waste shredded this year will weigh no more than the waste shredded last year". Does not this imply that the weight of waste can be equal or less but not more than last year. If it is equal the hospital wont be able to reduce its waste by half.
I find option B (more) correct than C. Please correct me if I am wrong.
Look at the question stem: "Which of the following is required for the updated waste removal program to achieve its aim?"
It is a kind of 'must be true' question. Which of the following is required...
The aim of the hospital is that the weight of the shredded waste this year should be half of the weight of shredded waste last year. For this to happen, it is necessary that the weight of the shredded weight this year be less than the weight of the shredded waste last year.
It is something like 'if I want T to be half of L, it is necessary that T must be less than L' - It is necessary, not sufficient.
Hence option (C) is correct.
As for B, we don't necessarily need it to be true.
"The total quantity of medical waste generated at the hospital this year will be no greater than that generated last year."
Look at the following scenario:
Last year: Total waste - 100 ton, shredded waste - 100 ton
This year: Total waste 110 ton, incinerated waste - 60 ton, shredded waste - 50 ton
Hence the aim can still be met even if the total quantity of medical waste generated at the hospital this year is greater than that generated last year.
