primary education mmu interview

I've got my interview this Wednesday and I am struggling to choose which the best topic is to talk about?

-Is the gender of the teacher an issue for children's learning in primary schools?
- From my perspective, as a learner, what makes a good lesson is…What I would do as teacher
to incorporate these ideas into my teaching.
- As a teacher, how I would support and encourage children's learning. 
-Some teachers say that there is no room for the wider curriculum of the arts and creativity, sports because of the pressure for children to achieve well in core as measured in national curriculum tests. What do you think the curriculum balance should be?
-What part should primary schools play in issues of sustainability and global warming? 
- Why do you think adding modern foreign languages to the primary curriculum is a good idea?
-A current educational issue that has caught my interest.
