Question

Toshio likes to look at stars. However, he cannot observe stars very well at night
because he lives in a large city. Last year Toshio visited the countryside where he
observed a large number of stars that he cannot see when he is in the city.
Why can many more stars be observed in the countryside than in large cities?
A) The moon is brighter in cities and blocks out the light from many stars.
B) There is more dust to reflect light in country air than in city air.
C) The brightness of city lights makes many stars hard to see.
D) The air is warmer in cities due to heat emitted by cars, machinery and houses.

Answer 1

Explanation:

The presence of excessive light fades the sky and hence less stars are visible. Usually country sides have less lights in comparison to large cities, making it possible to stargaze at night.
