Suppose your list is newlist. The following code is shorthand for "map the pure function defined by #[[1]] to each element of the list. Since each element of the list is a sublist, the mapping function is taking the first item in each sublist. Check out the Map command. newlist = #[[1]] & /@ list or: newlist=Map[First,newlist]
