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.
