Critical Reasoning (CR) | Re: In order to cut down on construction costs, the building

Expert,

I have one query, if I apply negation test on option d, then it comes out to be.. longevity will not be similar so it can be more than or less than the longevity of old material.

If it is more than ...than it will not shatter the conclusion.but of it is less than it will completely shatter.

So if it is the situation, can it be the answer?
