The suffix "-scope" is related to which of the following actions?

The suffix "-scope" is derived from the Greek word "skopein," which means "to look" or "to examine." Thus, it is directly related to actions that involve observation or examination. In the veterinary field, instruments such as endoscopes are utilized to visualize the internal structures of animals without invasive procedures. This ability to "examine" through visual means is what makes the option referring to examination the correct choice.

The other options do not align with the meaning of "-scope." For instance, bursting or puncturing involves physical actions that do not relate to visual observation. Enlargement pertains to increasing size, which also does not correlate with the examination aspect that "-scope" signifies. Therefore, the connection of "-scope" to the act of examining is clear and underscores its use in medical vocabulary.
