VII Read the following passage and decide whether the statements are True (T) or False (F)
Some day people will certainly try to build settlements on the moon The best places for houses in a moon town will be a cave or a tunnel Underground houses will not be squashed by meteorites that constantly fall on the moon from outer space This will be important on the moon, since daytime is so hot that food could be cooked in the rocks, and the nights get bitterly cold
Pioneer moon homes may be made of airtight plastic that can be blown up like a
balloon inside the cave The reason for this is that the moon has no air around it The
pioneers will have to take along from the earth the oxygen masks when they are away
from home But the balloon house itself will be filled with air Perhaps the house will
have beds, tables, and chairs, built into it These can be inflated, too So people will sleep,
eat and work on air! Moon-house building will be easy The moon’s gravity is less than
the earth’s Everything weighs only one-sixth as much as it does on the earth
Questions
1 In a moon town, what is the best place for houses?
2 Will the people on the moon wear oxygen masks when they leave their homes?
3 Why will the pioneers have to take along from the earth the oxygen they need for breathing?
4 If a stone weighs 18 tons on the earth, how much does it weigh on the moon?
5 According to the passage, can people build cities on the moon?
