Question

the microgravity, or little gravity, in outer space creates a feeling of weightlessness that can be difficult to adjust to. so, astronauts prepare for microgravity before traveling to space. to prepare, an astronaut might have to take a zero - g (zero - gravity) flight that simulates microgravity. zero - g flights are flown by highly trained pilots who follow special routes in the air that give passengers a chance to know what weightlessness in space is like.
complete the sentences to explain what happens when a flight simulates microgravity.
on a zero - g flight, passengers? little gravity without going into outer space. this type of flight allows passengers to? they are in outer space.

Explanation:

The text states that zero - g flights simulate microgravity and give passengers a chance to know what weightlessness in space is like. So, passengers experience little gravity on zero - g flights and have an experience as if they are in outer space.

Answer:

On a zero - g flight, passengers experience little gravity without going into outer space. This type of flight allows passengers to experience they are in outer space.
