extracting elements from multi-dimensional arrays

Hello all,

I have an array of the form:

list={{a1,b1,c1},{a2,b2,c2}...}

I'd like to get rid of elements of list based on criteria that apply to
the a's, b's and c's separately.  For example, I'd like to keep the
elements of list that have the following properties:

m < a < n
p < b < q

I know there's an easy way to do this, but I can't figure it out.  Any
suggestions?

Thanks!
dan
