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?
