I am doing this exercise from Armstrong's Topology book, and am super confused: 

> 
> "describe each of the following spaces: [...] $\mathbb{E}^2$ with each of the circles centre the origin and of integer radius identified to a point."
> 
> 
> 

First, there seems to be a grammatical error, and second, I am really confused how to approach this one, and what it is asking. I think that it is asking about circles centered at the origin and *only* of integer radius. (Maybe it means all circles, but only identify those which have integer radius?)

Also, when it says 'to a point' does it mean that all the circles are going to be identified with the same point?
