Question glue-words enable us to glue questions into one big question. $a = 1 $b = 5 if ($a & lt; $b) and ($b == 5) {print "hello"} In this example the glue-word and is used to glue 2 questions (a & lt; 5, b == 5) together. If one side of the and would answer false the whole question would answer false, because with the glue-word and both sides need to be true in order to answer true. Please do not forget to use the brackets around the questions!
