Question:
Select the most appropriate option to fill in the blank number 2.
Option 1: shall
Option 2: need to
Option 3: could

Correct Answer: may
Solution : The correct choice is the fourth option .
Using "may" suggests that there is a possibility that chewing gum after eating could potentially help neutralise the acidity in your mouth and throat. This word implies a likelihood but does not guarantee the result; it signifies a potential outcome without asserting it as a definite or absolute fact. Hence, it is the most appropriate modal verb.
