Final answer:
Belaboring a problem indicates excessive discussion, with option 3 being correct. Effective problem-solving requires calm, rational approaches and open communication.
Step-by-step explanation:
When two people are belaboring a problem, it specifically means that they are putting excessive effort into discussing the problem. Option 3 is the correct answer as the word 'belaboring' implies that there is an overly detailed or extended discussion about an issue, which can sometimes be counterproductive to finding a solution. This does not imply that they are discussing the matter calmly (option 1), avoiding it (option 2), or finding a quick solution (option 4). Effective problem-solving strategies typically involve identifying knowns and unknowns, remaining calm and rational, actively listening, and being open to discussion without assigning blame. By focusing on solving the problem together and using respectful communication, individuals are more likely to reach a resolution.
