foo = o while(foo =1980) : bar(foo) foo +=6 \# code fragment 1 starts on the next line for foo in range (1981,6): bar(foo) \# code fragment 2 starts on the next line for foo in range (0,1980,6): bar (foo) \# code fragment 3 starts on the next line for foo in range (0, 1980,7) : bar (foo) \# code fragment 4 starts on the next line for foo in range (1980,7) : bar (foo) \# code fragment 5 starts on the next line for foo in range (1980,6) : bar (foo) \# code fragment 6 starts on the next line for foo in range (0,1981,7) : bar (foo) \# code fragment 7 starts on the next line for foo in range (0,1981,6) : bar (foo) \# code fragment 8 starts on the next line for foo in range (1981,7) : bar (foo) Consider the event-controlled loop in the code fragment above and the eight counter-controlled loops beneath it. Which of these counter-controlled loops will perform precisely the same operations as the event-controlled loop? This question is internally recognized as variant 237. fragment 1 contains the correct code fragment 2 contains the correct code fragment 3 contains the correct code fragment 4 contains the correct code fragment 5 contains the correct code fragment 6 contains the correct code fragment 7 contains the correct code
