Explanation:

Flammable materials like alcohol can easily catch fire. An open flame provides a source of ignition. In a laboratory fire, the instructor has the knowledge and authority to handle the situation properly. Running for the extinguisher might waste time if the instructor can take more effective and immediate coordinated action. Throwing water might not be suitable (e.g., for some chemical fires). Opening windows can fan the fire.

Answer:

For the first question: an open flame.
For the second question: notify your instructor.
