Directions: 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 these four sentences and mark your response accordingly on the Answer Sheet.
S1: Temperature indicates the relative degree of molecular activity, or heat, of a substance.
S6: The boiling point of water under standard conditions is at 100 degrees Centigrade.
P: Temperature is an index of sensible heat, not a direct measure of the quantity of energy.
Q: Zero on this scale is the 'triple point' temperature, at which the gaseous, liquid, and solid states of water are at equilibrium under standard atmospheric pressure.
R: If heat flows from one body to another, the former has the higher temperature.
S: To indicate the temperature of a body, an arbitrary scale of reference is employed.

Explanation
S1 defines temperature as molecular activity; P clarifies it is an index of sensible heat, not an energy quantity. R links heat flow to temperature difference, S introduces the arbitrary reference scale, and Q fixes its zero at the triple point — leading to S6's 100 degrees Centigrade boiling point. PRSQ builds concept, then scale, then fixed points.
