BlackTom AI · Accepted Answer

The statement to analyze is: 'She only makes appointments after 5pm.' This implies a logical relationship between the time 'after 5pm' and the act of making appointments.
First, consider what the sentence logically says: whenever she makes an appointment, that appointment occurs after 5pm. In other words, being after 5pm is a prerequisite for the act of making an appointment; if it isn’t after 5pm, she cannot make an appointment according to the sentence.
Option: 'necessary' — This label fits because a necessary condition is something that must be true for the event to occur. Here, after 5pm must be true for her to make an appointment, so being after 5pm is indeed a necessary condition for the event of making an appointment.
Why the other potential interpretations don’t apply (even though no other options are listed in this item): if we claimed 'after 5pm is sufficient,' that would mean just being after 5pm guarantees an appointment, which the original sentence does not state—it's only restricting the times during which appointments can be made, not guaranteeing one simply by the time being after 5pm.
Additionally, saying 'after 5pm is the only time she makes appointments' would be an overreach beyond what the sentence specifies; the line only asserts a temporal restriction, not a claim about exclusivity beyond that condition.
In summary, the sentence establishes that the time condition after 5pm is required (a necessary condition) for the action of making appointments, rather than guaranteeing the action (sufficient) or asserting exclusivity beyond the stated condition.
