Step 1: Read the instructions carefully
Step 2: Skim all the questions briefly to get an idea of the topics for which you will be searching when reading the text.
Step 3: Read the first question again more carefully. Decide what you will need to read to answer the question. Is the question asking you for a particular detail that you need to find in the text? Or is the question asking you for an answer which requires a global understanding of the whole text?
Step 4: Once you have decided the best strategy for dealing with the question (as above), you will need to proceed to read the text in the appropriate manner, for example reading for gist, reading for detail etc.
