asking for advice

Okay, I have an interview tomorrow for a 6 month temporary position.

The question I'm afraid of being asked is about my prior temporary work - I've done a lot of temp work, so was that intentional? I'm afraid that either answer I could give might suggest I'm a flaky person (wanting to work temp jobs could suggest that I just have no commitment and will jump ship whenever, wanting to go permanent but not going permanent might imply I'm not worth hiring on a permanent basis).

What do you think I should say if I run into that question?

Thanks!
