Answer:

B.Build a model train and track, and test one train going around one curve at different speeds.

Explanation:

If Lillian wants to know how fast a train can move around a specific curve before it falls off the track, she must build a model of train and track and through that model she will test a train traveling through a curve at different speeds. That way she can analyze in detail the phenomenon she wants to observe and get answers.

She should never drive a train along a curve at different speeds until it falls off the track, because that would be very dangerous and irresponsible. For this reason, models are great for people to be able to analyze phenomena and situations that would not be right to analyze in real life.
