I am still inclined towards B, because if there is no enough glass available then the argument about profit would be futile. but the last statement i.e the conclusion is about cost and environment saving, and hence I am now really confused between B and D
Can anybody tell what is the exact point which makes D better than B
Bottle making process:
Step 0) (The enlightenment: coming up later )
a. Get raw material
OR
b. Get recycled glass
Step 1) Make molten Glass
a.
Raw material ---> Molten Glass (Requires more energy)
OR
b.
Recycled glass ----> Molten glass (Requires less energy)
Step 2) Make bottles
Molten Glass (from step 1) ---> BottlesEnvironmentalist's conclusion:
By using recycled glass instead of glass made from raw materials (
use step 1 -b, instead of step 1 -a), bottlers can lower their costs and benefit the environment at the same time.
Clearly, the Environmentalist is only considering the process of making bottles
after the bottlers have either Raw material or recycled glass ready with them (failing to address
Step 0). Sure, once you have the recycled glass ready, the process will be cost effective but what about the cost of getting the recycled glass? (
consider Step 0 now)
For the cost of making bottles from recycled glass to be lower than that of making bottles from raw material, the cost associated with obtaining recycled glass should be less than that of getting raw material -
AssumptionThis is choice D
B is actually out of scope:
Environmentalist is only saying that
If the bottlers use recycled glass instead of raw material, they can lower their costs. period!
Availability of recycled glass is none of his business. Even if there is no recycled glass available, what he concluded may still hold.
Just like-
By giving more mocks, you can score better on the GMAT.now, i dont care if the number of mocks that are currently created each year is enough for you. Even if it isnt, what i told still holds true.
Hope that helps
