Emma claims that a car cannot run if one of its essential parts, like the engine or the brakes, fails. Use your understanding of how different parts work together in a system to explain whether you agree or disagree with Emma’s claim.

• Disagree, because cars can function without all parts.

• Agree, because each essential part in a car has a specific role that is necessary for the car to function properly.

• Disagree, because other parts can replace the function of missing parts.

• Agree, because smaller components can take over the function of the missing part.
