A solved UPSC CDS/OTA PYQ - decoded step-by-step.
Solve it the standard way once - then learn the shortcut.
Directions: In the following question, the first and the last parts of the sentence are numbered S₁ and S₆. The rest of the sentence is split into four parts named P, Q, R, and S. These four parts are not given in proper order. Read the sentence carefully and choose the correct order from the given options. S₁: Hailstones consist of many onion-like layers of ice. P. The process continues until the hailstone is too heavy to be lifted and then it drops to the earth. Q. In certain weather conditions small ice crystals drop to form a crystal. R. Some of the moisture freezes on to the crystals forming another layer. S. Updrafts carry the hailstones and when it drops another layer is formed. S₆: That is how hailstones are formed.
Step-by-Step Solution
The complete worked solution.
Every step explained - no skipped algebra.
Q starts formation, P describes lift, R details layering, S ends with final condition. The logic behind this sequence often relies on connectors (like 'but', 'so', 'because'), temporal cues (like 'then', 'after that'), or thematic build-up (general to specific or cause to effect).
