(a) 1 only (b) 2 and 3 only (c) 2 only (d) 1 and 3 only 2. India is regarded as a country With "Demographic Dividend" This is due to (a) Its high population in the age group below 15 years (b) Its high population in the age group of 15-64 years (c) Its high population in the age group above 65 years (d) Its high total population
3. The distribution of powers between the Centre and the States in the Indian Constitution is based on the scheme provided in the (a) Morley-Minto Reforms, 1909 (b) Montagu-Chelmsford Act, 1919 (c) Government of India Act, 1935 (d) Indian Independence Act, 1947 4. The known forces of natures can be divided into four classes, viz., gravity, electromagnetism, week nuclear force and strong nuclear force. With reference to them, which one of the following statements is not correct?  (a) Gravity is the strongest of the four. (b) Electromagnetism acts only on particles with an electric charge. (c) Weak nuclear force causes radioactivity (d) Strong nuclear force holds protons and neutrons inside the nucleus of an atom. 5. With reference to Asian Infrastructure Investment Bank (AIIB), consider the following statements
  1. AIIB has more than 80 member nations.
  2. India is the largest shareholder in AIIB.
  3. AIIB does not have any members from outside Asia.
Which of the statements given above is / are correct? (a) 1 only (b) 2 and 3 only (c). 1 and 3 only (d) 1, 2 and 3 ANSWERS 1. (c) -Jet streams are relatively narrow bands of strong wind in the upper levels of the atmosphere. The winds blow from west to east in jet streams but the flow often shifts to the north and south. Jet streams follow the boundaries between hot and cold air. Since these hot and cold air boundaries are most pronounced in winter, jet streams are the strongest for both the northern and southern hemisphere winters. The “eye” of Tropical Cyclone is a roughly circular area of comparatively light winds and fair weather found at the center of a severe tropical cyclone. The eye is the region of lowest surface pressure and warmest temperatures aloft (in the upper levels) – the eye temperature may be 10°C warmer or more at an altitude of 12 km than the surrounding environment, but only 0-2°C warmer at the surface in the tropical cyclone (Hawkins and Rubsam 1968). The formation of an eye is almost always an indicator of increasing tropical cyclone organisation and strength. Because of this, forecasters watch developing storms closely for signs of eye formation. But in Extratropical Cyclones or Temperate Cyclones, there is not a single place where winds and rains are inactive (as in case of Tropical Cyclone). 2. (b) 3. (c) Government of India Act 1935 gives formula for power distribution among centre and states after independence which serves as basis for power distribution among union and states in Indian Constitution 4. (a) 5. (c) - Headquartered in Beijing, the Asian Infrastructure Investment Bank (AIIB) is a development bank established to boost lending for projects in sectors like energy, transportation, urban construction, logistics, education and healthcare. AIIB presently has 97 approved members worldwide. The Bank has invested in 13 member regions; it has members from outside Asia in Egypt (Middle East), Azerbaijan (Asia and Europe) and others. The three largest shareholders of the bank are China, India and Russia.
