replicate/simulate conditions of outer space

[Tan Elaine]

Astronauts have to undergo intensive training in conditions that replicate those of outer space.

The answer is replicate, I think the word should be simulate. Am I correct?

Thanks.

I suppose it depends on how they do it.

Replicate means to copy, whereas simulate means to give the appearance of.

Is there any information regarding the techniques used?

I would agree that "simulate" would be a more accurate term especially when it refers to "conditions".
