691. Read the passage and answer the question. Geckos can run up glass windows and even walk across ceilings. For a long time, people assumed they used suction or some kind of glue. Scientists now know that the secret lies in their toes, which are covered in millions of microscopic hairs. Each hair splits into even tinier tips that come extremely close to the surface, creating weak attractive forces between molecules. One hair alone produces almost no grip, but together they hold the gecko firmly. Engineers are now trying to copy this design to make reusable tapes that leave no sticky marks. What does the passage suggest about the grip produced by a single hair?

     कIt becomes stronger when the hair is wet. खIt is strong enough to hold the whole gecko. गIt is stronger on glass than on ceilings. घIt is too weak to matter on its own.

693. Read the passage and answer the question. Many people believe that summer happens when the Earth is closest to the Sun. In fact, the Earth is closest to the Sun in early January, during winter in the Northern Hemisphere. Seasons are caused by the tilt of the Earth's axis, which is about 23.5 degrees. For part of the year, the northern half of the planet leans towards the Sun, receiving more direct sunlight and longer days; at the same time, the southern half leans away and has winter. Six months later, the situation is reversed. When it is summer in Nepal, what season is it in Australia, according to the explanation in the passage?

     कspring खwinter गthe rainy season घsummer

696. Read the passage and answer the question. Flamingos are not born pink. Chicks hatch with grey or white feathers, and their famous colour develops only gradually. The pink comes from natural pigments called carotenoids, which are found in the algae and tiny shrimps that flamingos eat. The birds' bodies break down these pigments and deposit them in their feathers, skin and legs. A flamingo that eats less of this food will slowly become paler, which is why birds in zoos are often given special food to keep their colour. Based on the passage, which statement is TRUE?

     कFlamingos lose their colour when they grow old. खFlamingo chicks are brighter than adults. गA young flamingo's colour changes as it grows. घFlamingos produce carotenoids in their own bodies.

699. Read the passage and answer the question. At sea level, water boils at 100 °C, but the boiling point falls as air pressure drops. In high mountain villages, water may boil at only 85-90 °C, so rice and lentils take much longer to cook. A pressure cooker solves this problem by trapping steam inside a sealed pot. The trapped steam raises the pressure, which pushes the boiling point of the water above 100 °C. Food therefore cooks faster and uses less fuel, which is one reason pressure cookers are found in almost every kitchen in the Himalayan region. How does a pressure cooker make food cook faster?

     कIt lets steam escape from the pot quickly. खIt raises the boiling point of water by increasing the pressure. गIt heats food with electricity instead of fire. घIt lowers the boiling point of water.
