Question

choose the correct answer
which of the following means \había una vez\?
\many centuries ago\
\suddenly\
\once upon a time\

Explanation:

"había una vez" is a common Spanish phrase used to start stories, equivalent to the English story-opening phrase "Once upon a time". The other options do not match: "Many centuries ago" specifies a longer time frame, and "Suddenly" indicates an abrupt event.

Answer:

"Once upon a time"
