In the question given below,three paragraphs are given, which arejumbled. Find the correct sequence ofthese paragraphs so that they form ameaningful passage.
A. Climate change is warming the ocean,but its warming land faster and thatsreally bad news for air quality all overthe world, says a new University ofCalifornia, Riverside study. The study,published February 4 in Nature ClimateChange, shows that the contrast inwarming between the continents andsea, called the land-sea warmingcontrast, drives an increasedconcentration of aerosols in theatmosphere that cause airpollution. Aerosols affect the climatesystem, including disturbances to thewater cycle, as well as human health.They also cause smog and other kinds ofair pollution that can lead to healthproblems for people, animals, andplants.
B. To determine this, the researchersran simulations of climate change undertwo scenarios. The first assumed abusiness-as-usual warming model, inwhich warming proceeds at a constant,upward rate. The second model probeda scenario in which the land warmed lessthan expected. In the business-as-usualscenario, enhanced land warmingincreased continental aridity and,subsequently, the concentration ofaerosols that leads to more air pollution.
C. A robust response to an increase ingreenhouse gases is that the land isgoing to warm faster than the ocean.This enhanced land warming is alsoassociated with increased continental
aridity. The increase in aridity leads todecreased low cloud cover and less rain,which is the main way that aerosols areremoved from the atmosphere.

S1: This year many States have been badly affected by the drought situation prevailing in the country.
P: No better is the situation elsewhere, where floods have ravaged the standing crop.
Q: Though some have been less affected, even these are facing an uphill task in managing the situation.
R: Especially pitiable is the plight of the poor farmer who cannot afford a tubewell to irrigate his land.
S: Here the predicament is more equitable, for everybody's land is similarly submerged under ten feet of water.
S6: Either way, it seems the lot of the Indian farmer to be at the mercy of the elements.

The Proper sequence should be:

Read the following passage carefully and choose the most appropriate answer to the question out of the four alternatives.
When I think of my family's history on the land. I experience a pang of regret. Unlike much of the arid West, where the land has gone virtuallyunchanged for centuries, my place of origin, western Kansas, has been torn up by agriculture. The flat plains, excellent soil, and sparse but justadequate rainfall permitted farming; therefore farming prevailed, and a good 90% of the original sod prairie is gone. The consequence, in humanterms, is that our relationship to our place has always felt primarily mercantile. We used the land and denied, or held at bay, its effect on us. Yetfrom my earliest childhood, when the most of the Kansas prairie was still intact, I 've known that the land also had a romantic quality. I've feltmoved by the expanse of it , enthralled by size. I take pride in my identity as a plains daughter.
