choose 2 answers:

• the current driving mode (park/reverse/neutral/drive)
• the temperature in degrees celsius
• the fuel level of the gas tank (0-40)
• the warning light that indicates a seat belt isnt fastened
• the speed (0-120 mph)
• the eco label that indicates the car is in fuel - efficient mode (or not in fuel - efficient mode)

Explanation:

A single bit can represent two states (0 or 1, on or off). The warning light for seatbelt (on/off) and the ECO light (on/off) have two states. Other options (driving mode, temp, gas level, speed) have multiple states needing more than 1 bit.

Answer:

• The warning light that indicates a seat belt isn't fastened
• The "ECO" light that indicates the car is in fuel - efficient mode (or not in fuel - efficient mode)
