Have a look at the first two questions before you start reading the passage. This can help you read more actively and keep in mind the kind of information you require.
The answer to a question can be present anywhere in the passage. So do not decide and mark the answer unless you are sure after having gone through the whole document.
Keep a pencil and an extra paper for rough work. While you read, jot down the important points in the passage. This will help you to refer to the appropriate paragraph to find answer to any question. Don’t focus on minute details, instead note it in this list along with the paragraph where it occur.
Now don’t forget to look at the options with an eye to eliminate those which are contrary to any information given in the passage.
If there is an option(s), the information of which is not in the passage, most probably it is one of the wrong answers which you can reject. But beware, you must not reject an option in this way until and unless you have read the whole passage properly.
