GMAT Sentence Correction (SC) | As Vs Like: Correct and Incorrect usages

Hi Payal,

Can you please provide some insight into how to deal with statements which compare the quantity of two objects using "as".
Eg.: "This rock weighs twice as much as that one."

In these cases, I find the concept of "clause with a verb" after "as" not applicable. Kindly help.
