28. Select the word that means 'an undesired problem that is the result of some other event.'

Answer: A

Explanation:

Complication

Complication refers to an undesired problem that arises as a consequence of another event or situation. This term is often used in various contexts to describe additional difficulties that complicate a primary issue.

A) Complication

Complication is the correct choice as it directly aligns with the definition provided in the question. It encapsulates the notion of an additional problem that arises as a result of another event, making it the most suitable term.

B) Complement

Complement is incorrect in this context, as it refers to something that completes or goes well with something else. It does not convey the idea of an undesired problem stemming from another event, but rather signifies enhancement or addition.

C) Procedures

Procedures are systematic methods or processes for accomplishing tasks, which do not relate to the concept of an undesired problem. This term lacks the connotation of complication or adverse consequence that is central to the question.

D) Implemented

Implemented refers to the act of putting something into effect or action. This choice does not relate to the idea of an undesired problem; instead, it describes a process of execution, making it irrelevant to the question's focus.

Conclusion

Complication is definitively the right answer as it accurately represents an undesired problem resulting from another event. The other options fail to capture this meaning, either describing positive or unrelated concepts that do not align with the definition sought in the question.
