notify your instructor.
run for the fire extinguisher.
throw water on the fire.
open the windows.

Explanation:

• For the first question: Flammable materials like alcohol can catch fire easily. An open flame can ignite them. An open door, another student, or a sink do not pose the same ignition risk as an open flame.
• For the second question: In a laboratory fire, the instructor has more experience and knowledge to handle the situation safely. Running for the fire extinguisher might not be the best first step without proper training. Throwing water on some fires (e.g., oil - based fires) can make them worse. Opening windows can fan the flames.

Answer:

1. B. an open flame
2. A. notify your instructor
