Is Tessa available for work at the times listed below? Write the correct

LIBRARIAN: Well, Tessa, what I need to know now is what your schedule is like so that we can fit you into the roster here. Can I assume that you’re not able to work Monday to Friday during office hours?
TESSA: Right. I’m very busy with lectures, workshops and assignments during the week.
LIBRARIAN: How about week rights? Say five to seven in the evening? That’s a very busy time in the Children’s Section.
TESSA: Well, I couldn’t commit to more than three evenings a week and even then it would depend on my schedule.
LIBRARIAN: Yes, I understand. If possible, we could make arrangements a week in advance, would that help?
TESSA: Yes. That might work.
LIBRARIAN: Are weekends okay?
TESSA: Well, Sundays are out...actually, only every other Sunday, because that’s when I’m usually needed at the hospital. But I’m free on Saturday afternoons.
LIBRARIAN: All right, we could roster you for the odd weekend then. What about school holidays?
TESSA: Definitely, no problem whatsoever. I don’t have any other commitments during the holidays.
LIBRARIAN: That’s good to hear. We have droves of children here in the holidays as you can imagine. Thank you. Well, Tessa, we’ll send you a letter of appointment in the mail and we look forward to having you join us as a volunteer.
TESSA: Thanks very much.
LIBRARIAN: Now, as for your duties...
