$[6$ points$]$ Let $R(A,B,C,D,E)$ be a relation.

Assumption: the functional dependencies $AC$ and $AE$ hold over relation $R.$

Let the following be an instance of a relation $R(A,B,C,D,E)$ :

Figure $1.$

$2\mathrm{.}1.$ Can you identify any other functional dependencies that hold over R$?$

If no$,$ very briefly explain why not.

If yes, give an example of such a functional dependency. If you provide a functional dependency

as an example, it should be a non$-$trivial dependency with no redundant attributes. No justification

is necessary. $2\mathrm{.}2.$ Using the instance of $R$ provided above, complete the table below:
