Come on in and take a seat. My name is Sally Tinkleworthy.

Don't look so worried. All I want you to do at this stage is take a simple test to get your brain warmed up.

I'm going to ask you four easy questions. You have to pick the right answer to each one.

Here we go, then.

Question 1

Is a preserved railway inspector:

(a) an old railway inspector who has been pickled
or
(b) someone who inspects preserved railways?
