791. Read the passage and answer the question. Desalination is the process of removing salt from seawater to make it suitable for drinking or farming. Many modern plants use a method called reverse osmosis, in which seawater is pushed at high pressure through very fine membranes that allow water to pass but hold back salt. The technology has made life easier in some of the driest parts of the world. However, it has drawbacks. Plants need large amounts of energy, which makes the water expensive, and they produce a very salty waste liquid known as brine. If this brine is poured back into the sea carelessly, it can harm marine life. According to the passage, why is desalinated water expensive?

     कThe membranes must be imported खDesalination plants use a lot of energy गOnly a small amount of water can be produced घThe brine must be sold at a loss

793. Read the passage and answer the question. Before the middle of the fifteenth century, books in Europe were copied by hand, usually by monks or professional scribes. A single book could take months to produce, so books were rare and very expensive. Around 1450, Johannes Gutenberg, a goldsmith from Mainz in Germany, developed a printing system that used movable metal type. Individual letters could be arranged into pages, printed, and then reused. Within a few decades, printing workshops had appeared in many European cities. Books became cheaper, more people learned to read, and new ideas could spread faster than ever before. Which result of printing is NOT mentioned in the passage?

     कBooks became cheaper खMore people learned to read गIdeas spread more quickly घMany scribes lost their jobs

797. Read the passage and answer the question. Cities are often several degrees warmer than the countryside around them, especially at night. This is known as the urban heat island effect. Roads, roofs and concrete buildings absorb heat from the sun during the day and release it slowly after dark. Cities also have fewer trees and less open soil, so there is less evaporation to cool the air. In addition, cars, air conditioners and factories give off heat. Planners are now trying to reduce the effect by planting trees, creating parks and painting roofs in light colours that reflect sunlight. Which of the following is NOT mentioned as a cause of the urban heat island effect?

     कConcrete and roads absorbing heat during the day खA lack of trees and open soil गHeat given off by vehicles and machines घTall buildings blocking cool winds
