I feel like B is unlikely. Insertion issues don't fit here.

Just one activity per student, so it's a clear deletion issue.

I'm going to go with C) A deletion anomaly would occur. Seems like the most logical choice here.

Haha, the answer is obviously C) A deletion anomaly would occur. Who would even think an insertion anomaly would happen? That's just silly.

Hmm, I think the answer is B) An insertion anomaly would occur. If we remove the tuple, we won't be able to add new students to the database.

I'm pretty sure the answer is D) Both an insertion anomaly and a deletion anomaly would occur. Removing the tuple would prevent us from inserting new students and also delete existing data.

I remember practicing a question like this, and I think it had to do with how removing data can affect the integrity of the table.

I'm pretty confident on this one. Removing the tuple for Student_ID 1001 would mean we can no longer access that student's information, which would lead to a deletion anomaly. The answer is C.

Okay, let's think this through step-by-step. The key is the Student_ID, so if we remove that tuple, it would affect the ability to insert or delete data. I'm leaning towards C) a deletion anomaly.

The correct answer is C) A deletion anomaly would occur. Removing the tuple would mean we lose information about that student's participation, which is a deletion anomaly.

This looks like a classic database question about anomalies. I think I can handle this - I just need to remember the definitions of the different types of anomalies.
