Explanation:

The text gives a step - by - step process (not eating/drinking before, washing hands, cleaning the thermometer, placing it under the tongue, etc.) which is characteristic of teaching a procedure. The mention of keeping germs off (washing hands, cleaning thermometer) is just a part of the overall process of using the thermometer. And the normal body temperature is just an additional fact at the end, not the main purpose. The main focus is on the steps of using the digital thermometer.
