Question

Q1. Read the following passage carefully and answer the questions that follow:
All the stars we can see with our naked eyes are in the Milky Way galaxy, there are not so many of
these stars as one might think. They are not, as are in the habit of saying, countless. Not all the people
see the same number of stars. A person with good eyesight can see about 3000 stars on a cloudless
night. Of course, not all stars are bright enough to be seen without a telescope What stars a person
can see when he looks up at the sky on a clear night chiefly depends on three things --where he is on
earth, where the earth is on its path around the sun and what time of the night is.
Some stars can never be seen from some parts of the earth. The North Star for example,
which is almost exactly above the North Pole, can never be seen from the South Pole. In fact, the earth
itself shuts off the view of the North Star from the whole southern hemisphere.
(a)
How many stars can a person with good eyesight see? Why do we need the telescope to see
some stars?​
