4.27 Problems in this exercise refer to the following sequence of instructions, and assume that it is executed on a five-stage pipelined datapath:

ADD X5, X2, X1 LDUR X3, [X5, #4] LDUR X2, [X2, #0] ORR X3, X5, X3 STUR X3, [X5, #0]

4.27.1 [5] <4.7> If there is no forwarding or hazard detection, insert NOPs to ensure correct execution.

What would a pipleline stage diagram look like for this question?
