document.write( "Question 26952: Imagine you are at a school that has student lockers. There are 1000 lockers all shut and unlocked and 1000 students. Suppose the first goes along the row and opens every locker. Then the second student goes along and shuts every other locker beginning with the second locker. After that the third student changes the state of every third locker beginning with the third licker (if the locker is open the student shuts it, and if the locker is closed the student open it.) Next the fourth student changes the state of every fourth locker starting with the fourth locker. Imagine that this continues until the thousand students have followed the pattern with the thousand lockers. At the end, which lockers will open and which will be closed? and Why? \n" ); document.write( "
