Explanation:

For Question 24: Using the coarse adjustment knob on high power risks crashing the lens into the slide, damaging both, which is poor microscopy technique. The other options are proper practices: carrying with two hands supports the instrument, using both eyes reduces eye strain, and wrapping the cord prevents damage.
For Question 25: The only provided option for first action in a classroom fire is to alert others and evacuate via exits, which is the correct immediate safety response.

Answer:

Question 24: C. Turn the coarse adjustment and look through the microscope with high power.
Question 25: A. Head for the exits and tell everyone that the building is on fire.
