Reading Comprehension

Hi,

I am currently using the MGMAT RC book and i am finding it very helpful. I have two quick approach realted clarifications

- In the book it is suggested that one should read the question before before starting the passage. My question is - should i read only the question or the 5 given options aslo

- Second question - In the long passage approach, one is supposed to note done the keyword (can u help me with a more elaborate defination of keywords i.e. how to trace the key words and what kind) and again if you have to go back to the passage, should one read the options beforehand or only read them after re-reading the passage

Thanks,
SM
