PET Reading Part 6 Open Cloze

I'm having a fantastic time here in the UK and I thought I'd write (a)   tell you about somthing

As you know, I'm in a place called Cornwall, (a)   is in the south west

Cornish pasties have (a)   interesting history

After a hard morning's work the miners would sit down to eat (a)   lunch

But because of the job they were doing, their hands (a)   covered in dangerous materials

I don't know if it's true and (a)   seems a shame that they couldn't eat all of it!
