Hannah thought that maybe this was a trick question because obviously they were outside and wouldn't the obvious reason for being outside was because they were having a joint lesson the care of magical creatures? Surely the creatures they would be shown would be better suited outside. Still this seemed like a silly answer. Hannah may be a lot of things, but a slacker was not one of them. So she raised her hand and said "Professor I think the lesson is outside because that is a more appropriate place to learn about animals. Getting to see them in their natural habitat. To have more room to work with the animals. Also maybe some of the animals would not do well inside." Well she wasn't sure what else the professor was asking about unless he meant why the two certain professors were working together and in that case how in the merlin was she supposed to know that?
