The safety

[Rachel Adams]

Hello.

Does the first sentence sound more natural and can I use ''in'' instead of ''of''?

1. ''They improve the safety of their cars by putting dummies in them.''
2. ''They improve the level of the safety of their cars by putting dummies in them.''

It is "safety of (their) cars".
How can putting dummies in the cars per se improve their safety? You probably have not mentioned that the purpose of the dummies is to simulate real-life conditions for the purpose of testing the cars for safety.

Hello.

Does the first sentence sound more natural and can I use ''in'' instead of ''of''? You could, but I prefer "of".

1. ''They improve the safety of their cars by putting dummies in them.''
2. ''They improve the level of the safety of their cars by putting dummies in them." I would prefer, ''They improve the safety-level of their cars etc.".

You need to mention that they're 'crash-test dummies'.

You need to mention that they're 'crash-test dummies'.

But putting them in a car does nothing to improve its safety, except maybe by keeping people out of it.

You need to mention that they're 'crash-test dummies'.

And not people-dummies.

It's not a natural way of saying it.

They test the safety of their cars by using crash-test dummies.
