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.
Similar Questions
- S1: The primary evidence for climate change that occurred many million years ago is the rocks and deposits themselves.
S6: In other words, despite the clear legacy in many parts of the world of recent glaciation, the vast majority of sedimentary rocks were laid down in warm climatic conditions.
P: Sediments and fossil in the poles tell us a great deal about the environment in which they were laid down.
Q: We must, of course, bear in mind when interpreting this information that, because of the movement of the continents, no one latitude of the Earth has necessarily gone through such marked climatic vicissitudes.
R: Nevertheless, even allowing for this factor, one of the most remarkable discoveries about the climate change of the past is that the two poles of the Earth have been free of ice for at least 90 per cent of the known history of the planet.
S: We may find in close proximity to one another, coal deposits indicating the humid conditions of the tropics, red sandstones laid down in deserts and morainic materials reflecting polar conditions. - S1: Temperature indicates the relative degree of molecular activity, or heat, of a substance.
S6: The boiling point of water under standard conditions is at 100 degrees Centigrade.
P: Temperature is an index of sensible heat, not a direct measure of the quantity of energy.
Q: Zero on this scale is the 'triple point' temperature, at which the gaseous, liquid, and solid states of water are at equilibrium under standard atmospheric pressure.
R: If heat flows from one body to another, the former has the higher temperature.
S: To indicate the temperature of a body, an arbitrary scale of reference is employed. - S1: The Tungabhadra is the chief tributary of the Krishna formed by the union, near Kudali, of the two streams Tunga and Bhadra.
S6 : The Tungabhadra has served as a historic natural frontier right through the centuries.
P: The river is perennial in character and comes down in frequent heavy rushes during the rains.
Q : The rain-bearing river was dammed by the rulers of Vijayanagara near Hampi for watering the palaces and gardens of that great city.
R : The united stream strikes in a north-easterly direction through Mysore and skirts the adjacent districts.
S: The bed of both the headstreams of the Tungabhadra is rocky. - S1: In July 1917, Prince Lvov was replaced by a socialist revolutionary Alexander Kerensky as the head of the provisional government.
S6: In Russia the Soviets have been in existence since 1905, and the Soviet system played a especially important role under the Provisional Government.
P: However, such a partial replacement failed to satisfy the Bolsheviks.
Q: The revolutionaries did not want a parliamentary republic nor a bourgeois democracy but rather they wanted a soviet of workers, soldiers, and labourers.
R: When the February Revolution broke out, the leader of the Bolsheviks, Lenin, was in Switzerland.
S: He arrived in Russia in April 1917, and was followed by Trotsky. - S1: Glaciation has important effects on the landscape beyond the direct modifications created by ice erosion and deposition.
S6: At the same time, ice advanced from the Welsh mountains into the Vale of Evesham and combined with northern ice to pond up a large proglacial lake covering much of the Midlands.
P: One example is that glaciation frequently disrupts pre-existing drainage lines, initiating a new pattern persisting after the ice has disappeared.
Q: The Midlands, what is now the Coventry/Warwick area, was formerly drained by the head waters of the River Soar, flowing into the Trent south of Nottingham.
R: Two well-documented instances of such effects occur in England.
S: During glaciation, the valleys of Soar and Trent were occupied by ice advancing from the north. - S1: Every geological period has been dominated by one particular form of life; as conditions changed to those of a new period, different types of organisms emerged into dominance.
S6: The origin of completely new biological systems is comparatively rare, so consequently only a few major types have developed during the history of life.
P: Individual shifts rely on opportunity, ecological access, and the development of a new adaptation.
Q: Characteristically these shifts are rapid and are followed by a bout of adaptive radiation into the new ecological zone for example, with the emergence of life on land.
R: Within each period, natural selection has created a vast array of adaptive experiments culminating in a breakthrough to a new biological system that may cross the ecological barrier to the next period.
S: Every breakthrough of shift in dominance is dependent on ones that have occurred before so that the process of evolution is progressive. - S1: A seasoned cricketer catches a cricket ball coming in with great speed far more easily than a novice, who can hurt his hands in the act.
S6: The conclusion is clear: force not only depends on the change in momentum, but also on how fast the change is brought about.
P: The novice, on the other hand, keeps his hands fixed and tries to catch the ball almost instantly.
Q: One reason is that the seasoned cricketer allows a longer time for his hands to stop the ball.
R: Consequently, he needs to provide a much greater force to stop the ball instantly, and this hurts.
S: He does this by drawing his hands backward in the act of catching the ball. (P) and the outcome in cases selected in prior years'
