Proverb Meaning Analysis

The proverb ‘Politeness costs little but yields much’ suggests that being polite requires minimal effort or expense but results in significant benefits or rewards.

Evaluating the Options

• Option 1: Being polite is desirable. While true, this option doesn't fully capture the 'costs little, yields much' aspect. It states politeness is good but not its specific value proposition.
• Option 2: Politeness is a virtue that pays in long run. This option aligns perfectly. 'Pays' directly relates to 'yields much', and the phrase implies a worthwhile return on the minimal effort ('costs little') involved in being polite over time.
• Option 3: Politeness is powerful. Politeness can indeed be powerful, but the proverb focuses more on the cost-benefit ratio – the high yield relative to the low cost.
• Option 4: Politeness can make people repent or win. This is too specific and doesn't represent the general meaning of gaining significant benefits from minimal cost.

Conclusion

Option 2 best reflects the meaning of the proverb by highlighting that politeness is a valuable trait ('virtue') that provides substantial benefits ('pays') over time, even though the initial effort ('costs little') is small.
