 By our choice of $n$ and $n'$ we see that the corresponding morphism
 $\varphi' : X \to \mathbf{P}(V')$ is a closed immersion. Thus if we choose
 $s' \in \Gamma(X, \mathcal{L}^{\otimes n'})$ not vanishing at $x$,
-then $X_{s'} = (\varphi')^{-1}(D_+(s')$ (see
+then $X_{s'} = (\varphi')^{-1}(D_+(s'))$ (see
 Constructions, Lemma \ref{constructions-lemma-invertible-map-into-proj})
 is affine and $X_{s'} \to D_+(s')$ is a closed immersion.
 Then $s = s_1 \otimes s' \in V_n$ does not vanish at $x$.
