If a simple pipelined processor is super-pipelined by a factor of 3 (the alu takes 3 cycles instead of one for the smallest operation), back-to-back dependent instructions require stall cycles to be inserted even with perfect bypassing.

Explanation:

If it is super pipelined with ALU taking 3 cycles the back to back dependent instructions require to insert 2 stall cycles as the control unit can stall the execution of the pipeline as as the ALU takes time in execution using 3 cycles. This is done so in order to avoid a hazard in the pipeline.

the answer would be 2

since they are only saying that the couple has 20 daughters and so on but they never said that they went to the movies as well therefore the couple was the only people that went to the movies.

hope this ! : 3

that without the operating systems you would have to control and synchronize computer hardware.
