For aCa \in \mathbb{C}, let A={zC:Re(a+z)>Im(aˉ+z)}A = \{z \in \mathbb{C} : \text{Re}(a + z) > \text{Im}(\bar{a} + z)\} and B={zC:Re(a+z)<Im(a+z)}B = \{z \in \mathbb{C} : \text{Re}(a + z) < \text{Im}(a + z)\}. Then among the two statements:

(S1): If Re(a),Im(a)>0\text{Re}(a), \text{Im}(a) > 0, then the set AA contains all the real numbers.

(S2): If Re(a),Im(a)<0\text{Re}(a), \text{Im}(a) < 0, then the set BB contains all the real numbers.
