With no explanation, label text_A→text_B with either "DON'T KNOW", "NO" or "YES".
text_A: MIPS has 32 floating-point registers. Two registers are paired for double precision numbers. Odd numbered registers can be used for arithmetic, branching or as part of a double precision register pair, resulting in 16 usable registers for most instructions (moves/copies and loads/stores were not affected).
text_B: If arithmetic is successfully performed on a register, can it be an odd numbered register?
YES.
