Answer 1

The reason behind holding thermometer in the mouth instead of the armpit is to reduce procedural errors.

Explanation:

If thermometer is kept in mouth or below tongue it gives core internal temperature of the body. While thermometer under armpit reads surface temperature i.e., it reads temperature lower than actual value of temperature. Therefore, we get temperature variation due to procedural error.
