Answer:

The answer is option A) Attributes of different entities should not be mixed in the same relation.

Explanation:

A tuple is a set of attribute values in which no two distinct elements have the same name. Thus, in some accounts, a tuple is described as a function mapping names to values.

An attribute value is an attribute name paired with an element of that attribute's domain.

Informally, each tuple in a relation should represent one entity or relationship instance.

Therefore, attributes of different entities should not be mixed in the same relation.

katrin [286]

Answer:

an unconscionable contract

Explanation:

Unconscionable contracts are contracts that are considered so unjust, unfair and one-sided that they shock the conscience. This type of contracts are usually voidable and not enforceable.

In this case, the seller had the superior bargaining power, because the other party didn't speak English, and took advantage of that position to make an extremely unfair deal. A court would void this transaction.
