Question

how have crumple zones improved since their initial invention? select all that apply. they deform less in a crash. they are used in more areas within cars. they are built from materials that absorb force better. they can be built smaller.

Explanation:

Crumble zones are designed to absorb energy in a crash. If they deform less in a crash, it means they are not functioning as intended (they should deform to absorb energy). So the first option is incorrect.

Over time, crumple zones have been implemented in more areas of cars (like the rear in addition to the front), so the second option is correct.

Better - absorbing materials (e.g., advanced alloys and composites) have been developed for crumple zones, so the third option is correct.

With better materials and engineering, crumple zones can be made more efficient (smaller in size while still performing their function), so the fourth option is correct.

Answer:

B. They are used in more areas within cars, C. They are built from materials that absorb force better, D. They can be built smaller
