Why do we have $\frac{L'}{L}(1+r+it) \ll \frac{\zeta'}{\zeta}(1+r)$

Question

I am currently reading Ten Lectures on the Interface Between Analytic Number Theory and Harmonic Analysis. On page 166, it states

$\frac{L'}{L}(1+r+it) \ll \frac{\zeta'}{\zeta}(1+r) \ll \frac{1}{r}$

1. Why is this true?

2.(Here should I assume $\frac{L'}{L}(1+r+it)$ refers to $\frac{L'}{L}(1+r+it, \chi)$?
