In the following question, select the word which would replace the question mark (?).
Eye : Myopia :: Teeth : ?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Pyorrhoea
The pair links an organ with a disease of that organ: myopia (short-sightedness) is a defect of the eye. In the same way, pyorrhoea is a disease of the teeth and gums, in which the gums are infected, pus collects round the teeth and the teeth become loose.
Why the other options are incorrect
Option (2) Trachoma — Incorrect. A bacterial infection of the eye that scars the inner eyelid, so it belongs with the eye.
Option (3) Cataract — Incorrect. A clouding of the lens of the eye, again a disease of the eye.
Option (4) Hypermetropia — Incorrect. Long-sightedness, a defect of the eye like myopia itself.
