Which of the following is not a method of reducing antibiotic resistance?

1. Doctors should not prescribe antibiotics inappropriately, such as treating non-serious or viral infections

2. Humans should all take a low does of antibiotics daily to prevent the development of resistance amongst bacteria

3. Patients should complete their course of antibiotics so all bacteria are killed and none survive to mutate and form resistant strains

4. The agricultural use of antibiotics should be restricted.
