Illusion [34]

The correct answer is A; rub a penny on a wart and then throw the penny away to get rid of the wart.

Further Explanation:

There are many people who still use a penny to get rid of a wart on their hand or other part of the body. It is part of the American folk medicine and is an example of continuous magic in America and other parts of the world.

Rubbing a penny on a wart and throwing the penny away will not get rid of the wart. A doctor can remove the wart or use a special type of medicine to help the wart come off on its own.

Folklore medicine is still used by people of ages, races, wealthy people, and people who practice Wiccan.

*rub the wart with a raw bean cut in half

*tie a silk string around the wart

*put a toad on the wart
