a) Let X = { a, b, c,d, e }, if B = {{a,b},{d,c}, {e, f}}forms a basis for X, find the topology generated by B. b) Let B = {(a, b) : a,b e Q} be the collection of open intervals in R with rational endpoints. Show that: (1) B is a basis for some topology on R. (2) The topology generated by B is the usual topology on R.
