The one who is rich possesses many superfluous things.

needless
superior
essential
expensive

The correct answer is A. needless.

Superfluous means more than is needed or wanted. In this case, the person who is rich possesses many things that they do not need. These things may be expensive, but they are not

essential to the person’s life.

The other options are incorrect because:

  • Superior means better than others of the same kind. In this case, the person who is rich does not necessarily possess things that are better than others of the same kind.
  • Essential means necessary or very important. In this case, the person who is rich does not necessarily possess things that are necessary or very important to their life.
  • Expensive means costing a lot of money. In this case, the person who is rich may possess expensive things, but these things are not necessarily superfluous.
