Introduction: It needs proper concentration and attentiveness to find out any logic of a proposition. Logic is based on judgment and common sense. You need to be careful before you infer a conclusion.
Arrange the four parts P, Q, R and S between A and B in order to make a sensible story or a sequence of a story.
A: About three o'clock in the morning, Jane, one of the servants awoke us. She had seen a great fire from her window. I looked. The fire was not that far away, but I saw no threat to us and returned to bed.
P: From a high point near the Tier of London, I could see a huge fire raging on both sides of the bridge. We had friends who lived in that area. Worried, I approached the bridge. An intense fire was raging out of control. People were desperately trying to save their belongings, loading them in boats or flinging them into the river. Some stayed in their homes until the fire nearly touched them before making their escape.
Q: I rose at seven. The fire appeared smaller and farther away. Jane said she had heard that over400 houses had been destroyed during the night, and the fire was still raging near London Bridge. Curious, I went to have a look.
R: A high wind was driving the fire deeper into the city. Seeing no attempt to put it out, I sped to the King's castle. After telling what I had seen, I was ushered before his Majesty. At my suggestion, the King commanded that houses in the immediate path of the fire be torn down. In this way, we hoped to control its spread. I left to take the King's message to the Mayor. To the King's message, the Mayor replied, 'What can I do? People will not obey me. I have been pulling houses down, but the fire moves faster than we do?
S: He left me, and I walked home. No one could think of a way to stop the fire. It seemed to feed on all it found: pitch and tar in the homes; oil, wines and brandy in the warehouse, and other things. The people I passed seemed distracted. Many filed into churches, not to worship, but to store their goods. Others loaded carts with their belong gangs. Ready to run down anyone in their path, they fled from street to street.
B: Sparks fell from the sky like rain. Smoke filled the sky. A horrid, malicious, bloody flame leaped as far as the eye could see. Its noise was a horrid, cracking sound. At home, my wife and I packed those valuables we could and prepared to evacuate.

A: One of the largest mangrove forests in the world and a unique tiger habitat, the Sunder bans in West Bengal is facing a serious threat to its ecosystem from poaching and felling of trees.
P: A forest officer attributed the depletion of the mangroves to the increasing levels of salinity, mostly in the western part of the Sunder bans. In the 16th century, the western part of the region rose, and in the process the entire region got tilted towards what today makes up Bangladesh. As a result, the main branch of the Ganga, the Ghaghara, shifted eastwards and ultimately began to flow through the Padma.
Q: The Sunder bans is situated at the mouth of the Bay of Bengal, in the Ganga _ Brahmaputra delta. Known for its biodiversity, the region has been identified as a World Heritage Site. Although forest of ficialsdeny that any felling of trees has been going on, the increase in there gion's population has led to the exploitation of the Sunder bans. Most people in the region are poor and depend on the forest for livelihood and, more specifically, their firewood needs.
R: With the passage of time rest of the branches of the Ganga also started flowing eastward. Consequently, sweet water inflow in the western part of the Sunder bans got greatly reduced.
S: The blame does not lie with the poor local residents alone. There is a major racket being run in the Sunder bans by timber merchants, who bribe forest officers and workers and get a free hand in collecting as much timber as they wish. This flies in the face of claims made by forest officers that the indiscriminate felling of trees has been brought under control. The Sundari tree, a variety of mangrove from which the Sunder bans got its name, is fast vanishing from the region as it has become one of the prime targets of the timber merchants.
B: For the proper growth of mangroves, the ratio of salt water and sweet water should be 50:50 owing to the lack of sweet water in the western part, the forest cover is less dense and the mangroves there are of the dwarf and bushy type.

A: Acid rain is pollution that falls to the earth as rain that is more acidic than natural rain. Scientists also include mist, hail, sleet, and snow, in the term acid rain.
P: Many scientists feel that these human activities produce most of the acid rain that falls. Scientists call acid rain a long-range pollutant. The sulphur and nitrogen needed to make acid rain can travel long distances in the atmosphere. Acid rain can then fall hundreds of miles from the sources of nitrogen and sulphur that produced it.
Q: In some places, the rain is so acidic that it eats away at human-made objects such as buildings. Acid rain forms when water and certain gases in the atmosphere mix. These gases contain sulphur and nitrogen. This mixture produces sulphuric and nitric acid. These acids later fall to the ground in acid rain.
R: Acid rain is a serious problem all over the world. It weakens and kills many organisms. In some places, acid rain has permanently damaged trees, flowers. For example, trees affected by acid rain may not be able to prepare properly for cold weather. Acid rain has also caused many streams, lakes, and other bodies of water to become too acidic for fish and other living things to live and reproduce in them.
S: Some of the sulphur and nitrogen in the atmosphere comes from natural sources. These include forest fires, volcanic eruptions, and lightning. However, human activities - such as burning coal and oil in factories and power plants and burning fuel in cars and trucks ? also produce huge amounts of sulphur and nitrogen.
B: Thus, the fish in a stream in Vermont or the trees in a forest in Massachusetts may be harmed by acid rain caused by sulphur from smokestack in Ohio or Pennsylvania.
