Exercise 5, § 2

Give an example of a right A-module E, a left A-module F and two submodules $F', F''$ of F such that the canonical image of $E \otimes F'$ and $E \otimes F''$ in $F' \otimes F''$ is not the intersection of the canonical images of $E \otimes F'$ and $E \otimes F''$ in $F' \otimes F''$ (cf. Exercise 3(a)).
