Which of the following arguments is faulty because the middle term is covered by the absence of the major term and not by its presence?

The faulty inference is 'sound is eternal because it is produced'.

The major term is 'eternal' and the middle is 'produced'.

Whatever is produced is found precisely where eternality is absent.

Produced things are the non-eternal things, so the middle keeps company with the absence of the major.

A reason tied to the absence of what is to be proved actually supports the opposite conclusion.

This is the contradictory (viruddha) reason, covered by the major's absence, not its presence.
