Which month comes before "junio"?

The correct choice is May. In the context of the Spanish calendar, "junio" refers to the month of June. The month that comes directly before June is May, which in Spanish is "mayo." Understanding the structure of months in both languages can clarify the sequence, helping learners recognize that May is the month that precedes June, rather than any other options listed. These other months—April, March, and February—come before May in the calendar.
