A team of engineers is designing new safety features for cars. The team designs four separate safety devices. To test them, each device is placed on a car, and all of the cars go through a standard collision test. Below is a record of the test findings. Based on the data collected, what can the engineers do to design the safest car?
Create a new design for a car that includes all of the safety features that were tested.
Start over from scratch, since the four safety features did not score consistently in the test.
Keep the new design for the airbags and combine them with the bumper that wraps all the way around the car.
Incorporate upgraded shock absorbers and bumper material into the new car, since these features performed the best.

When Tom mixed a clear liquid and a dark liquid together, the mixture got warm and bubbled. Tom wanted to determine whether a chemical reaction occurred, so he measured some properties. His measurement are in the table below. Based on Tom's data, did a chemical reaction occur?
No. Liquid B and Liquid C both burn in air, so they are the same substance.
No. The color of Liquid C is the same as Liquid B, so they are the same substance.
Yes. Liquid C has a different density than Liquid A or Liquid B, so new substance has formed.
Yes. The mass of Liquid C is not the same as Liquid A or Liquid B, so a new substance has formed.
