What to do

Work through these resources and questions, and refer to the equipment. Don't worry about getting all the questions right – you'll be able to review your answers, learn from them if necessary, and retake this exercise as many times as you like.

There are several flexible scopes displayed, in varying conditions. Examine them carefully, and then answer the questions below.
