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
