How should people wearing spectacles work with a microscope? 

  • A
    They should keep on wearing their spectacles.
  • B
    They should never use the microscope.
  • C
    They should take off their spectacles.
  • D
    They may either put on their spectacles or they may take off their spectacles.

Answer

  1. They should take off their spectacles.

Explanation:

If operators using a microscope usually wear spectacles (glasses) for activities such as working at their PC, they often need to remove them when looking through a microscope so they can align their eyes correctly with the eyepieces.
