In the following question, select the word which would replace the question mark (?).

Eye : Myopia :: Teeth : ?

Pyorrhoea

The correct answer is Option (1) → Pyorrhoea

This is an analogy question where the relationship between the first pair (Eye : Myopia) needs to be matched in the second pair.

Let’s break it down:

• Myopia is a disease/condition of the eye (specifically, short-sightedness).

• So, the analogy is:Organ : Disease related to that organ

Now, apply the same to Teeth : ?

• Pyorrhoea is a disease of the gums and teeth (a type of periodontal disease).

Why other options are incorrect:

• Trachoma → Disease of the eye, not teeth

• Cataract → Eye disease (lens clouding)

• Hypermetropia → Eye condition (farsightedness)
