Setting exam questions

My job for today is to set exam questions for my portion of a first-year module. I'm in charge of the phonology bit (lord knows why) so I need ten reasonably easy exam questions on phonological transcription, stress, intonation, assimilation, etc. It's hard to know what they will find far too easy or far too hard, so I'm trying to vary the difficulty a bit. They're made easy by virtue of the fact that it's an online exam, so they're all either multiple choice or short answer. I won't put them on here, for obvious reasons (I don't think any of my students read my blog, but you never know, and that might cause a rather sticky situation...).
