Hi lillian,
Well, I wasn't sure whether to use dedicated or devoted so I did a little search on the web and found sentences like:
"This exhibition is dedicated to...." but of course that wasn't the one we wanted.
Other results:
"This exhibition is devoted to the Music of..." and that was an example.Try it yourself!
and I picked the word accordingly. Anyway, given the choice I'd pick "directed at".
'devote' gives the sense of 'consecrate' (life) to sth or sb. It's usually about the church, God, a cause, etc
Another use is as: "giving priority to sth"
But in both cases the subject is usually a person. See what I mean?
