 The algorithm used here, however, will generate a random number between zero and
 the number of lines read, every time a line is read. Then, if that number is
-greater than one, the line will be taken as the resulting line, for that moment.
+smaller than one, the line will be taken as the resulting line, for that moment.
 
 Of course, when more lines are read after that, any line can be picked in that
 fashion, _where the chance the line is picked is still equal for evey line_.
