how can astronaunts talk to one another on the moon where there is no air.
1 air is not needed
2. heavy boots
3. ratio transmission
4. staying inside a preassurised suit
Which answer do you think is correct? Why?
Note the following misspelled words: ratio (radio?) preassurised (presurized/presurised?)
Ooops -- PRESSURIZED/PRESSURISED
Some of those multiple choices are pretty funny. Which ones can you eliminate? Do they talk with their boots?
