Esperanto in Scotland, Chapter 6, Exercise 3
One possible answer.

Mia instruistino veturis al kongreso en Bergeno.
Ŝi parolis Esperanton kun homoj el multaj landoj.

Meaning: My teacher travelled to a congress in Bergen. She spoke Esperanto with people from
many countries.

Check: "instruistino" is feminine (-in-), so "ŝi" follows; "veturis" is past tense (-is);
"el multaj landoj" - the plural adjective agrees with the noun.
(Use "Mia instruistino" for a female teacher; a male teacher is "instruisto".)
