Concept:Judging the strength of arguments related to a proposed law on mandatory community service.
Explanation:Argument I is strong because civic responsibility benefits society and such laws exist in many countries.
It promotes unity, empathy, and social welfare.
Argument II is also strong because compulsory service limits personal choice and freedom.
When service is forced, volunteers may not be sincere, which can lower the quality of work.
Thus, both the positive social impact and the negative practical concern are valid points.
Answer:Both I and II are strong.
Correct option: D. Both I and II are strong.
