Question: Both bits feed into the adder, so why is the answer ALUControl0 and not both ALUControl0 and ALUControl1? I know that only B feeds into
Both bits feed into the adder, so why is the answer ALUControl0 and not both ALUControl0 and ALUControl1? I know that only B feeds into the upper multiplexer. Please only answer this question if you are 100 percent sure. All the information needed is shown in the table and the schematic.

(2) Both bits of the ALU Control Signal feed into the bottom multiplexer, shown in blue. Which bit(s) feed into the adder and the upper multiplexer, shown in red
