;i'm taking a topic test and don't know quite what the best choice for this one is. word choice in an argumentative essay should be:
simple and general.
completely neutral.
emotional and exaggerated.
formal and precise.

Formal and Precise

Argumentative essays are those essays which provide a perfect solution to convince someone about an idea or opinion that is why their style of writing should be formal. The tone, the choice of words and the way those words are put together must be less personal and precise. For instance we want to provide information about an incident, we should use its exact date and time which means we should be precise.

the best practice

1. keep your workspace clean

2. wash your hands

3. seperate and clean chemicals and equipment

4.   use microfiber cleaning utensils

5. clean and sanitize all work surfaces

hope this !
