The passage consists of six sentences. The first and sixth sentences (S1 and S6) are given. The middle four sentences (P, Q, R, S) are given in jumbled order. Find out the proper order for the four sentences. S1: Most people who have come close to death say they remember nothing. P. It may permanently change a person’s perceptions of what is real and important Q. The near-death experience is among the most powerful experiences that a person can have. R. That ‘something’ might be a near-death experience. S. However, a third or more may later report that ‘something happened.’ S6: However, one extraordinary aspect of near-death experience is that a person’s culture, religion, race or education does not affect the pattern of the experience.
