Each item consists of six sentences of a passage. The first and sixth sentences are given as S1 and S6. The middle four sentences have been jumbled up and labelled as P, Q, R and S. Find the proper sequence.
S1: For several million years, humans lived by hunting wild animals and gathering wild plants.
S6: As a result, conditions were favourable for the growth of grasses such as wild barley and wheat.
P: This led to the development of farming and pastoralism as a way of life.
Q: This change took place because the last ice age came to an end about 13,000 years ago and with that warmer, wetter conditions prevailed.
R: Then, between 10,000 and 4,500 years ago, people in different parts of the world learnt to domesticate certain plants and animals.
S: The shift from foraging to farming was a major turning point in the human history.
The correct sequence should be
- AQSPR
- BSPQR
- CPSQR
- DRPSQ
Explanation
R starts the turn to domestication ('Then, between 10,000 and 4,500 years ago'), P its result (farming and pastoralism), S names the shift a turning point, Q explains its cause (end of the ice age), and S6 gives the climatic result. RPSQ; the other orders put the effect before the cause.
