Answer 1

The color of smoke indicates both the type of fuel and phase of a fire.

Step-by-step explanation:

The sensory clue that indicates both the type of fuel and phase of a fire is the color of smoke. Different types of fuels produce different colors of smoke when they burn, and the color of smoke can also indicate the phase of a fire, such as whether it is just starting or is fully developed.
