J. Maitland asks what is being done to stop thefts. Crack down on the rise = reduce. Rates of theft/the number of thefts on power substations.

Being offensive.

Yes.

Neither REALLY make sense, but both are ok by me. I've never thought about punctuating this. Maybe better to leave it to spoken English, because it does break down when you try to make sense of it. I definitely would say it as a week's holiday, even though the holiday doesn't belong to the week. A week-long holiday actually makes sense. A week holiday works for me, but don't make it a weak holiday!

Nailed it in one. They're all great.

Edgar is right. In this case that can mean the same thing and subtlely different things. Technically, "working for herself" implies she likes the act of working, and "to work for herself" implies she prefers that to working for somebody else. But in the real world, you can use them interchangeably.

Both sentences are correct. Apostrophes are appropriate (not brackets.) I grew up with titles needing to be capitalized and underlined. Underlining has gone away, but not the captialization. Good luck.
