I've shortened the advice, as there were lots of statements repeated, for exampe giving the formula for the area, then justifying it with a diagram, and then giving the formula again. Fixed typos and reworded the questions to remove duplication of "the following..." in the statement and parts.

This is OK. Could have been more variation (other reflection lines, shapes overlapping the reflection line...), but not really worth an overhaul, as it fits in with the other transformation questions.

Originally split from a larger question on converting units, but basically a new question.

There was no mark assigned to part a). I've fixed that, but otherwise looks good.

Split from a larger question, for which this part was incorrect. I've fixed the conversion for cm$^3$ to litres and removed the conversion to gallons, as this was not useful. I've replaced this with conversion from cm$^3$ to m$^3$, which is more useful, and a common problem for students.

I've ripped this apart enough to warrant marking it "needs to be tested" rather than "ready to use".
