S6: However, eradicating lantana is a long and arduous process which can only be carried out with a lot of technical expertise and financial commitment.
P: Since then, it has spread over six lakh square kilometres, covering fifty percent of the country's natural areas.
Q: Research also shows that the lantana has invaded most pasture lands in the country.
R: It was introduced in the country as an ornamental plant by the British in the 1800s.
S: A 2020 estimate by researchers shows that the plant occupies forty percent of forests, including tiger reserves.
Understanding Lantana Plant Passage Sequencing
The question asks to arrange the jumbled sentences P, Q, R, and S to form a coherent passage, given the first (S1) and last (S6) sentences.
Analyzing the Sentences
- S1: The lantana plant is not native to India. (Introduces the topic and its foreign origin.)
- S6: However, eradicating lantana is a long and arduous process... (Serves as a concluding statement about the difficulty of removal.)
- R: It was introduced in the country as an ornamental plant by the British in the 1800s. (Explains *how* and *when* it came to India, logically following S1.)
- P: Since then, it has spread over six lakh square kilometres, covering fifty percent of the country's natural areas. (Details the spread chronologically from the introduction mentioned in R.)
- S: A 2020 estimate by researchers shows that the plant occupies forty percent of forests, including tiger reserves. (Provides a specific, recent statistic on its spread, elaborating on P.)
- Q: Research also shows that the lantana has invaded most pasture lands in the country. (Adds another significant area of invasion, complementing the spread mentioned in P and S.)
Sequencing the Jumbled Sentences
Let's construct the logical flow:
- S1 sets the stage: lantana is not native.
- R explains its introduction: as an ornamental plant by the British in the 1800s.
- P follows, describing the subsequent spread: over large areas since its introduction.
- S provides a specific, recent data point on its extent in forests.
- Q adds further information about its invasion into pasture lands.
- S6 concludes by highlighting the difficulty of eradication, which is a consequence of its widespread invasion.
Therefore, the correct sequence of the jumbled sentences is RPSQ.
Final Passage Order
The complete, logical order is: S1 -> R -> P -> S -> Q -> S6.
The sequence of the middle sentences is RPSQ.
