Hi guys,
1. I have two sentences that are in doubt but presuming they are correct, can you tell me why one is be proper to have an article while the other is not?
The interest rate is 3.5 percent.
Unemployment, already a low 3.5 percent, is expected to fall further ...
I agree with Julie that it should be 'The unemployment rate', but although 'at' is possible, I don't think it is necessary.
The article is used because the speaker is thinking of a variety of possible interest rates. You could say 'The unemployment rate, already 3.5 percent', but the presence of 'low' requires 'a'.
2. Why is there an article "a" rather than "the" or the absence of any of them?
There is a Garden of Eden somewhere out there.
Because the speaker is using 'Garden of Eden' to refer to a whole possible range of places that are like the Garden of Eden.
Best wishes, Clive
