Answer :

Final answer:

Engineer is a problem solver, hence the correct answer is 3) Engineer.

Explanation:

Engineers apply principles of science and mathematics to develop solutions for technical, societal, and commercial problems. They are often involved in designing, testing, and building various projects, all of which require significant problem-solving capabilities.

A bus driver might solve day-to-day operational issues, a painter might tackle creative challenges, a journalist resolves informational problems through investigation and reporting, and a poet could address expressive and linguistic puzzles. However, the engineer's core responsibility and training is aimed at technical and systematic problem-solving, which typically covers a broader range of complex issues compared to the other professions mentioned.

This aligns with the notion that an engineer is often employed in situations that necessitate specialized skills to devise practical and efficient solutions, much like the computer science skills an engineer would use over painting as indicated by the reference provided.
