Question

car makers have an idea to make cars \talk\ to one another. how would this work?
a one car would give off a signal that another car would pick up.
b cars would have names and voices.
c cars would use magnets to attach to one another.
d one car would play music and another would record it.

Explanation:

To determine how cars "talking" to each other works, we analyze each option:

• Option A: In vehicle - to - vehicle (V2V) communication, cars use wireless technology to send and receive signals (like about speed, location, etc.). This is a practical way for cars to "interact" or "talk".
• Option B: Giving cars names and voices is a fictional or anthropomorphic idea, not a real - world way for cars to communicate for safety or traffic management purposes.
• Option C: Using magnets to attach is not related to communication; it would be for physical connection, not "talking".
• Option D: Playing and recording music is not a way for cars to communicate relevant information (like traffic conditions, etc.).

Answer:

A. One car would give off a signal that another car would pick up.
