Interest in work increases what?

Correct answer: Motivation and performance

The direct answer is A: interest in work increases motivation and performance. Interest means that a person feels attention, willingness, or enjoyment while doing a task. When work feels meaningful, the person is more ready to begin it, continues with greater concentration, and tries to do it well. The reasoning is simple: interest creates involvement; involvement increases effort; steady effort usually improves performance. Interest does not guarantee perfect results, but it generally supports better work. Option A is correct because motivation gives energy and purpose, while performance means the quality or effectiveness of the work. Option B is wrong because sadness and delay are usually problems that interest may reduce, not results that it normally increases. Option C is wrong because interest generally encourages attention and care rather than disorder and mistakes, although mistakes can still happen for other reasons. Option D is wrong because procrastination means postponing work and confusion means lack of clarity; both are contrary to focused involvement. Remember: interest makes a person want to work, and wanting to work supports motivation and performance.
