B. READING COMPREHENSION
I. Read the passage carefully and choose the correct answer.
You have probably heard about the unappealing dried foods that astronauts eat in space, such as the chalky ice cream and powdered pea soup. That means all the water is removed from those foods. But did you know that there are more than 90 different food and drink items on NASA`s space menu? (NASA is the American government organization concerned with spacecraft and space travel. NASA is an abbreviation for `National Aeronautics and Space Administration`)
Many food items are dehydrated to prevent bacteria growing, so water must be added before consumption. But some foods look like those ready meals you find in the supermarkets, made hot in the microwave. In fact, the chefs have recently provided some gorgeous meals for the space crew. Astronauts choose their individual food selections on Earth, getting to taste it all first beforehand.
Drinking is another matter. Although much is brought up with the astronauts and in cargo deliveries, a lot is recycled from human waste water. Yes, the water they use could have been someone else`s urine a day ago. You cannot be squeamish if you are an astronaut!
