@AlexHaro there is! click on the individual question and click on the explanation tab.

For those who need some help with the Kumar example, it’s not a valid argument because it runs counter to the logical flow. Just because Kumar is 17 minutes past the bell doesn’t necessarily mean he’ll be properly cited as late. He might have had a doctor’s appointment and was allowed to come to class tardy, meaning he will not be properly cited as late. Simply because he falls within the ‘5+ minutes’ superset doesn’t imply that he falls within the ‘late’ subset.

@VanillaCat yes!
