One must have an eye on two questions at the same time ,,,, don't stray in the passage finding just one answer,,,, Underline your key words in the questions (atleast two at the same time --- in this way if you dont manage to find the first but possibly you will find the answer to second question and ultimately it will save your time !!! ) then attempt to hit those keywords in the passage....
It isn't necessary to be aware of the each and every word in the passage,,, you are free here to predict things conceptually when you are entangled with those words you never heard or know the meanings ...!!!
You are neither required to understand the whole passage nor it is the test of your knowledge ,,,,, just take it as you are just there to provide the answers to the questions !!!!!
Hope it may work for you !!!
