I think the answer is
Job
1. Will you teach me that card JOB, Joey?
2. My brother doesn’t miss a JOB when it comes to making money
3. A little but of glue will do the JOB and your teapot will be as good as ever, Mum.
Not sure but hopefully it is •-•
2. the audience's location
Explanation: It's this option because the other choices does not matter if the presentation is online, the location does.
