Given below are six sentences of a paragraph. The first and last sentences are fixed as S1 and S6. Rearrange the four sentences P, Q, R, and S between them to form a coherent paragraph. S1: The minimum thermometer has a large bore and its fluid is colourless alcohol. S6: The daily temperature is recorded since a permanent, continuous record of temperature is desired. P: When the meniscus moves up the bore it leaves the index behind to register the lowest temperature. Q: Resetting the dumbbell of the minimum thermometer is accompanied by the action of inverting the stem until the index slides down to the meniscus. R: A tiny, dark index in the shape of a long dumbbell is placed in the bore below the top of the alcohol column. S: It is mounted horizontally and as the alcohol contracts with the decreasing temperature the meniscus of the alcohol pulls the index down.
