In this exercise, we examine how data dependencies affect execution in the basic 5-stage pipeline described. Problems in this exercise refer to the following sequence of instructions: I1: lw $r1,36($r2) I2: add $r2,$r1,$r4 I3: and $r5,$r1,$r2 [3 points] Indicate dependencies that can cause data hazards. Mention the register involved.

I1: lw $t0, 0($t1) I2: lw $t2, 4($t1) I3: add $s2, $t2, $t3 I4: sub $s0, $t0, $t3  [2 points] In the following instructions, point out the hazard(s), if any. Please state the instructions involved in the hazard(s) and identify the register involved in the hazard.
