B. Read the text and answer the following questions.
Sohan lives in a village in the south-west part of Bangladesh. Last night he could not sleep. His sister had her SSC exam next morning. She could not read either. There was load-shedding. The summer night being muggy and hot, life became hell without electricity. Most of their area remained dark for hours due to power shortage
In May-June, temperature shoots up to 40 degree Celsius. With almost 90 percent of humidity in the atmosphere, it becomes all wet, damp and sticky. When you are busy fanning yourself all the time, how can you concentrate on studies? In the night it is impossible to sit down to study with a candle light or table lamp or hurricane lamp or a rural kerosene lamp. People simply come out of houses almost bare-bodied and sit in the open places. Some splash cold water on their faces. Fans remain unmoving, electric bulbs are off and it is dark everywhere. It is simply unbearable.
What is the reason of frequent load shedding? Press reports say there is a shortage in electricity production. According to the Power development authorities, the demand for electricity a few years ago was more than 6,000 MW* a day while the supply remained around 4,200 MW. In the rural areas, the Rural Electrification Board (REB) could supply barely half of the total demand which was around 2,400 MW per day. In the capital city, the demand stood at around 1,400 MW while the supply amounted to 650 MW. As a result, load-shedding is unavoidable for the time being. But situation is improving very fast.
*MW is Megawatt which is a unit of power used to measure the output of a power station.

G. What steps do you think can the government take to fight shortage of electricity?
The government have to set up new power-plants to produce more electricity. They should also try to use the alternative sources of electricity such as sunlight. They should arrange campaigns to encourage people to cut their use of electricity short through different alternative plans.
