‘P’ will be the first part of the given sequence as it begins by introducing the idea of the passage, that is, ‘Everyone expected me to win that Olympic event hands down’. ‘S’ will come next as it is in continuation with the previous statement and gives a reason for sentence ‘P’, that is ‘A year before I had set the world record of 26 feet 3 inches.’ ‘Q’ will come next as it is in contrast to the previous statements, which is indicated from the words, ‘I was in for a surprise’. ‘P’ will follow logically as it talks about the reason for ‘Q’ which is indicated from the words, ‘When the time came for the long jump trials, I was startled to see’. Hence, PSQR is the correct sequence. Thus, option (b) is correct.
