SSC Selection Post Phase 14 (Higher Secondary Level)17 Sep 2026Shift 2Sentence Rearrangement (PQRS)

Which of the given options is the most logical sequencing of the following sentences to form a meaningful paragraph?

1. He introduced his theory of evolution in the book "On the Origin of Species"
2. Charles Darwin was a naturalist who studied plants and animals.
3. He traveled to the Galapagos Islands, where he observed unique species.
4. His theory changed the way scientists understood the development of life.

Answer और ExplanationAnswer and explanation

Answer: (C) 2-3-1-4

आरंभिक वाक्य: 2 में पूरा नाम और परिभाषा है, Charles Darwin was a naturalist। वाक्य 1, 3 और 4 He या His से शुरू होते हैं, इसलिए इनमें से कोई आरंभिक वाक्य नहीं हो सकता।
कड़ी: 2 डार्विन का परिचय देता है → 3 (He traveled to the Galapagos Islands, जहाँ उसने प्रजातियों का अवलोकन किया) → 1 (He introduced his theory in the book, अवलोकनों के बाद) → 4 (His theory changed..., जिसके ठीक पहले सिद्धांत का नाम आना आवश्यक है)।
✓
2-3-1-4
2-1-3-4 में 1-4 की जोड़ी टूट जाती है: 1 का सिद्धांत और 4 का His theory साथ-साथ आने चाहिए।
Opener: 2 has a full name and a definition, Charles Darwin was a naturalist. Sentences 1, 3 and 4 start with He or His, so none of them can open.
Chain: 2 introduces Darwin → 3 (He traveled to the Galapagos Islands, where he observed species) → 1 (He introduced his theory in the book, after the observations) → 4 (His theory changed..., which needs the theory to be named just before it).
✓
2-3-1-4
2-1-3-4 breaks the pair 1-4: the theory in 1 and His theory in 4 must sit side by side.

बाकी Options उत्तर क्यों नहीं हैंWhy the other options are not the answer

A1-3-4-2 में 1 से आरंभ हुआ क्योंकि सिद्धांत मुख्य बात है। परंतु वाक्य 1 'He' से आरंभ होता है, जिसके लिए पहले कोई नाम नहीं है, अतः यह आरंभ नहीं कर सकता।1-3-4-2 opens with 1 because the theory is the main point. But sentence 1 starts with 'He', which has no earlier name to refer to, so it cannot open.
B2-1-3-4 में 2 से आरंभ सही है। परंतु वाक्य 1 सिद्धांत बताता है, जबकि वाक्य 3 में उसकी ओर ले जाने वाली यात्रा बाद में आती है; घटनाओं का क्रम उलट गया।2-1-3-4 opens correctly with 2. But sentence 1 gives the theory before sentence 3 describes the voyage that led to it, so the order of events is reversed.
D4-3-1-2 में 4 से आरंभ हुआ क्योंकि वह परिणाम बताता है। परंतु 4 में 'His theory' है, जो अभी न आए सिद्धांत की ओर संकेत करता है, अतः यह आरंभ नहीं कर सकता।4-3-1-2 opens with 4 because it states the result. But 4 says 'His theory', which refers to a theory not yet introduced, so it cannot open.
