(1)Suppose that people verified in 2004, that all zeros of $\zeta(\sigma+i t)$ with $0<t<T<=10^{22},0<\sigma<1$ are on the critical line ($\sigma=1/2$).
(2)Suppose Bob proved in 2010 that for $t>=10^{2000}$, all the zeros of $\zeta(\sigma+i t)$ are on the critical line.
(3)Suppose that Alice verified in 2020 that for $10^{22}<=t<=10^{2000}$, all the zeros of $\zeta(\sigma+i t)$ are on the critical line.
Question: Who is considered to have proved the Riemann Hypothesis? (i) Bob (ii) Alice (iii) Bob and Alice
