Is the square root of 48 rational or irrational?

No that is not true as is displayed by the book 'A modest Proposal'

Explanation:

A modest proposal is one of the most brilliant pieces of satire ever written and presents a very absurd argument.

The point is not to make the people to agree to the argument but to say that what it represents is based in reality and morally abhorrent.

By laying a factual and well argued claim for the fact one actually foes on to claim that the practice should not be done as it is wrong even though its being justified by the text itself

This is the prime point made by the text .
