Question

current research shows that, overall, self - driving automobiles are significantly safer than human - driven vehicles. for instance, waymo (formerly googles self - driving car program) has logged more than two million miles on u.s. roads and has been to blame for only one accident as of 2017. statistically, this makes googles self - driving vehicle ten times less likely to cause an accident than even the safest human drivers. moreover, the vehicle is forty times less likely to cause an accident than new drivers, such as teenagers who have just gotten their drivers license. to illustrate the potential impact of driverless cars on teen safety, a study concluded that if all teen drivers in the u.s. were to trade in their keys for self - driving cars, one million accidents per year would be eliminated.
select the two pieces of evidence that the author provides for the following supporting claim. self - driving cars on the road are safer than cars driven by people.
a study found that self - driving cars could prevent one million teen accidents per year.
an expert claims that self - driving vehicles will dramatically improve the speed of traffic.
research shows that an automated car is forty times less likely than a new driver to cause a crash.
a study shows that autonomous vehicles are fifty times more reliable than even the safest drivers.

Explanation:

The claim is about safety. The first option mentions preventing teen accidents (safety - related). The third option compares automated cars to new drivers in terms of crash likelihood (safety - related). The second option is about traffic speed (not safety). The fourth option has an incorrect comparison (the text says ten times less likely than the safest human drivers, not fifty times more reliable).

Answer:

A. A study found that self - driving cars could prevent one million teen accidents per year.
C. Research shows that an automated car is forty times less likely than a new driver to cause a crash.
