Consider the following relation ANY:

ANY $($aid$,$ bid, cid, aName, bName, cName, since, description, location$)$

and functional dependencies F that hold over the relation ANY:

See the picture

Determine all candidate keys $($possible primary keys$)$ of ANY.

$2.$ In which normal form is the relation ANY and why?

$3.$ If relation ANY is not in $1$NF$,2$NF or $3$NF then decompose it$,$ accordingly, taking care to

denote possible keys $($both PKs and FKs$).$
