They seem too vague.

It is the first one most likely.

A seems to be the most logical to me.

Your post messed up the thread! I can't see below it!

Nah, it's B.

It's a monthly study done by contacting households, not buisnesses.

KASZ WAS RIGHT.

I went to economics today, asked my teacher, and he let us know that the correct answer is B.

Yeah, your teacher is a bit tricky.  Most people probably picked A because they know Labor are the people who post the results.

Key though is, they get the numbers from individual households.  Only way to do it really.

A is not a number...

Get my joke?

I'd say it's a toss between a and b. I'd pick B- I remember hearing about that on the news.

slight edit- i see you already got the answer. ah well xd
