In this question there is six sentences of a passage. The first and sixth sentences are given in the beginning as S1 and S6. The middle four sentences in each have been jumbled up and labelled as P, Q, R and S. You are required to find the proper sequence of the four sentences and mark your response accordingly. S1 : Things are often not what they seem. S6 : This happened without you even knowing it. So imagine the changes that occur to this earth and humanity. P : But you are really not, because the Milky Way galaxy, of which you are a part, is moving through space at 2.1 million kilometre an hour. Q : So in roughly twenty second that it would have taken you to read this paragraph, you have already moved thousands of kilometre. R : And that is without taking into account the effects of earth’s rotation on its own axis, its orbiting around the sun and sun’s journey around the Milky Way. S : As you read this sentence, perhaps sitting in a comfortable chair in your study, you would probably consider yourself at rest.
