Hi Laura!
If LIMIT is not applicable (e.g. you want to query for many similar
resources in one query), you can also consider using SAMPLE (with a
GROUP BY).
If you want to make the choice deterministic, you can use LIMIT together
with ORDER BY.

Yeah I'd prefer one over the other, but I don't think there is any simple way
to distinguish them, I think multiple values are just supposed to be unordered.
I'll end up using LIMIT or DISTINCT. Thank you.

Do you care about which one?
If not, just use the LIMIT keyword to get only one. Otherwise, it's going to
depend on which one you want and how you want to distinguish them.

If I have this node
:Alice :name "Alice", "Alice Smith" ;
:age 25 .
how can I return *only one* of the ":name" properties with SPARQL? For example return
("Alice", 25)
