The correct answer is: D. Neither I nor II is strong
Argument I is not strong because it does not provide any evidence to support the claim that scrapping the system of formal education beyond graduation will lead to people taking employment at an early date. It is possible that people would still choose to pursue further education even if it were not compulsory, or that they would find other ways to gain the skills and knowledge they need to be successful in the workforce.
Argument II is not strong because it does not provide any evidence to support the claim that scrapping the system of formal education beyond graduation will lead to a lack of depth of knowledge. It is possible that people would still be able to acquire a deep understanding of their chosen subject matter through other means, such as independent study or apprenticeships.
In conclusion, neither argument I nor II is strong enough to support the claim that we should scrap the system of formal education beyond graduation.
