Long passage strategy question

How to approach a long passage question with too many details of a process.

Finding the main idea becomes too difficult. In this particular case , what strategy should we apply?

The best approach we can follow for long passage is

  1. Find main idea for each paragraph
  2. Find relation between each main idea from 3 paragraphs(assuming long passage is of 3 paras)
  3. Sum them all three based on their relationship

That’s your main idea of whole passage

Tricks:

  1. Most likely the first paragraph introduces something and later paras talk about pros and cons of it
  2. Always read the first paragraph completely. Then in next paras the first two lines in each paragraph will give you an idea of what that para is talking about
