What question will a reader who is unfamiliar with scientific equipment most likely ask?
O What is a pipette and a concave slide?
O How long does the procedure take?
O Why do people prepare wet-
mount slides?
O What is the purpose of the paper towels?

A). What is a pipette and a concave slide?

Explanation:

As per the question, the most likely question a reader unaware of the scientific equipment would ask would be that 'what is a pipette and a concave slide.' This is because he needs to know about what these equipment(Pipette and a Concave slide) are and their uses for understanding the procedure. Without knowing that a pipette is a small tube with an enlargement or bulb in the middle for transferring measured quantities of liquid and a concave slide is a microscopic slide used for examining comparatively thicker samples, they would not be able to either understand the process or follow it. Thus, option A is the correct answer.
