Your Answer for Question 1:
Registers will be read incorrectly and the incorrect values will be used for computation. When trying to read from a register, it may have not been updated, because an instruction before may still be executing, thus the wrong value is retrieved and the program spitting out invalid data. There would be no delays, but data will be used incorrectly.

Your Answer for Question 2:
These signals are coming from the EX/MEM, ID/EX and the MEM/WB. Essentially these are futher down in the cycle and the new values are being written into. Depending on what stage you are in, determines which signal is written and sent to the register. So if it was a write then a read, the read would be at the EX/MEM stage since there's a one cycle delay.

Your Answer for Question 3:
The EX, MEM, and WB control fields of the ID/EX pipline register is et to 0. There is an ID used to determine what bubble to use. This is read to figure out what bubble to use.
