Answer C


3. Stars twinkle because
A. the intensity of light emitted by them changes with time
B. the distance of the stars from the earth changes with time
C. the refractive index of the different layers of the earth's atmosphere changes continuously, consequently the position of the image of a start changes with time

Answer C

4. It takes much longer to cook food in the hills than in the plains, because
A. in the hills the atmospheric pressure is lower than that in the plains and therefore water boils at a temperature lower than 100oC causing an increase in cooking time
