Final answer:
Before starting a short-term test, the occupant should take some of the mixture and place it in a test tube. They should also follow safety guidelines, answer questions in groups, and record observations during the experiment.
Step-by-step explanation:
Prior to initiating a short-term test lasting for 2 to 3 days, one should instruct the occupant to take some of the mixture and place it in a test tube that is about one third full. They should expect to stay home and rest if they have a fever, not attend class or go out with friends, and see a doctor if the fever lasts longer than 48 hours.
For a lab experiment, the occupant should divide into groups of three and spend about 20 minutes answering questions together. They should follow safety guidelines given in lab instructions and obey directions carefully.
During the experiment, the occupant should remove the stopper from a test tube, hold a lit candle at the mouth of the test tube, and record their observations. Additionally, they should avoid staying up all night before a test or eating a big meal just before the test and try to relax during the test by taking deep breaths.
