Q1. Discuss the choices that have to be made in towns where many people make their living from the sea.

A growing number of cities are stepping up to the challenge of sea-level rise. Most of them literally have no choice. Alongside mitigating their carbon footprints through reducing emissions, there are basically three ways that states and cities are taking action. First, they are fielding hard engineering projects like sea walls, surge barriers, water pumps and overflow chambers to keep water out. Second, they are adopting environmental approaches involving land recovery and the restoration of mangroves and wetlands to help cities cope with floodwater inundation. The third strategy involves people-oriented measures including urban design, building resilience and retreating after all other options have been exhausted.

The good news is that coastal cities are not starting from scratch – most of them have deep stores of knowledge and expertise. For centuries, cities bordering oceans and waterways have had to contend with local sea-level fluctuations and periodic storms. Many coastal cities have experimented with a combination of all three types of measures for hundreds of years. But past successes do not necessarily guarantee future safety. Today’s cities are different from their predecessors. Many of them are of an unprecedented size and complexity. Complicating matters, sea levels are rising more rapidly than in the past, in some cases overwhelming local capacities to respond. A growing number of wealthy states and cities are making massive investments in technical solutions to keep seas at bay. It is true that large infrastructure schemes including barriers and break-walls can at least temporarily reduce the risks of losses. But an overreliance on concrete walls and pump systems to beat back rising tides, storm surges and downstream floods can only go so far. The lesson from the most successful cities is that a combination of approaches is essential. What is more, environmental-based solutions to reinforce the existing ecology’s protective capacities are not only effective, but lower cost. One country that has pioneered these multi-prong measures is the Netherlands.

Explanation:

read this excerpt from “incidents in the life of a slave girl.”

i went about my evening work with trembling steps. mr. flint twice called from his chamber door to inquire why the house was not locked up. i replied that i had not done my work. "you have had time enough to do it," said he. "take care how you answer me! "

i shut all the windows, locked all the doors, and went up to the third story, to wait till midnight. how long those hours seemed, and how fervently i prayed that god would not forsake me in this hour of utmost need! i was about to risk everything on the throw of a die; and if i failed, o what would become of me and my poor children? they would be made to suffer for my fault.

at half past twelve i stole softly down stairs. i stopped on the second floor, thinking i heard a noise. i felt my way down into the parlor, and looked out of the window. the night was so intensely dark that i could see nothing. i raised the window very softly and jumped out. large drops of rain were falling, and the darkness bewildered me. i dropped on my knees, and breathed a short prayer to god for guidance and protection. i groped my way to the road, and rushed towards the town with almost lightning speed.

what is the main idea of this excerpt?

harriet worked for a man called mr. flint who became very impatient when she did not finish her work.

harriet waited until after midnight to run down the stairs and jump out of a window into the rain.

harriet was a frightened young girl who found the faith and courage to leave her home for an unknown life.

harriet felt very nervous about running away because she did not like being alone in the darkness.
