Hi Expert,
According to GMAT Club, the correct answer is E. I am confused about the answer option given by GMAT Club. i can't accept their answer; I am with option A. I am giving an analogy, which will support the choice A not E. So, could you please help me by giving your explanation?
I'll boil water until rice is cooked.
>>if rice is cooked, then i'll stop boiling.

I'll boil water as long as rice is cooked.
>> after rice is cooked, i'll STILL boil the water. Every work has objective. Here, my objective is to cook rice. If my objective is successful, why will I carry on my works?
Thanks...
