Question: 
Suppose we unify complex numbers with points on the complex plane. Let z1 and z2 be two complex numbers, both at a distance of 2 from the origin of the coordinate system. Additionally, let z1 lie on the positive real axis and z2 on the positive imaginary axis. From the complex numbers listed below, choose all whose distance from z1 is less than their distance from z2.
