Yes, if you've represented information in the way that I've described,
this query would succeed if there's a graph ?r1 that Astrid said that
contains the triple `?x ?y <CountryZ1>` and there's a graph ?r that
Tia said that contains the triple `?x ?y <CountryZ>` _and_ which has
all the other metadata, too (i.e., saidOn, saidAt, confidence, and
comment).
