Show answer
Concept: Start with the sentence that introduces the subject; pronouns and 'this' follow later.
- P introduces 'the group of astronomers' – opener.
- Q ('They… telltale dimming') follows; S explains 'This slight dimming' – so Q before S.
- R gives the result (discovery) – last.
Trick: 'This dimming' (S) must come right after the sentence that first mentions dimming (Q) – Q-S pair fixes the answer.
Answer: (C) P, Q, S, R
अवधारणा: पहले वह वाक्य जो विषय का परिचय दे; 'They/This' वाले वाक्य बाद में।
हल:
- P में astronomers का परिचय है – पहला वाक्य।
- Q में 'dimming' पहली बार आया, S उसी 'This slight dimming' को समझाता है – Q के बाद S।
- R में परिणाम (खोज) – अंत में।
ट्रिक: Q-S जोड़ी (dimming → This dimming) से उत्तर तय हो जाता है।
उत्तर: (C) P, Q, S, R
