In this section each item consists of 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: The equatorial zone is generally over 200 centimetres annually. S6: It is also noted that a larger part of the rainfall is received in the afternoon, very rarely in the early morning or at night. P: The ascending air currents become saturated and produce heavy rainfall. Q: Over the land areas, most of the rain falls in the afternoons when the convectional system is well developed. R: The high level of precipitation is mainly due to the high temperature which causes rapid evaporation of moisture. S: This high level of precipitation is largely confined to land areas in the windward slopes and the inter-tropical convergence zone where the general upward motion is well marked.
