READING COMPREHENSION TEST 3

I. At any ocean beach you can see the water rise up toward high tide. Something 

is pulling the water up. We now know that the moon is doing the pulling. How can 

it pull? We call the pull gravitation. All matter everywhere pulls all other 

matter everywhere. The bigger the object, the greater the pull. The moon is big 

enough to pull the earth, and it pulls the water on the earth. The moon pulls 

the water facing the moon. When you see high tide, you know that the moon is 

pulling the water up.

A. When you drop something, and it falls to the ground, it falls because of -

II. The sun also pulls the earth. However, the sun is much farther away from the 

earth than the moon, and so the pull, that is, the gravitation, is less. 

Sometimes, the sun and the moon pull together on the same side of the earth. 

Then, the high tide is very high, indeed.

III. Why does oil not mix well with water? We know that water mixes well with 

water. If you add hot water to cold water, you soon have lukewarm water. 

Alcohol, too, mixes well with water. Alcohol and water are quite similar. Water 

is composed of oxygen and hydrogen, whereas alcohol is composed of oxygen, 

hydrogen, and carbon. Why do oil and water not mix well? The reason is that they 

are not similar. The molecules of water, that is, the tiny pieces of water that 

include oxygen and hydrogen, are very small, whereas the molecules of oil are, 

by comparison, enormous and very different in their composition.

A. Water molecules include -

IV. From where does a flower get its smell? It gets its smell from an oil that 

the plant produces. The oil is volatile. Long ago, volatile meant flying. The 

oil seems to be flying, for it escapes into the air. Insects that smell the oil 

fly to the flower, where they leave behind them the pollen that the flower needs 

to grow seeds. Some plants do not need insects to bring pollen. They depend on 

the wind to bring it. These plants usually have little smell or no smell at all.

V. There are several birds, once common, that have died out in the last few 

hundred years, so that now not one of them exists. The dodo was quite common on 

the island of Mauritius 300 years ago, but there is not one alive today. It was 

easy prey to animals new to the island, because it could not fly on its small 

wings. In New Zealand there used to be birds called moas, which were twice as 

high as the biggest man. They have all died out. The great auk, which used to 

come in thousands to the shores of Newfoundland, is another bird that has died 

out in the last few hundred years.
