Question

si es solsticio de verano en el hemisferio norte, ¿qué está sucediendo en el hemisferio sur?
a invierno
b otoño
c primavera
d un monzón

Explanation:

The Earth's hemispheres experience opposite seasons due to the tilt of the Earth's axis. When it is summer solstice in the Northern Hemisphere (maximum tilt towards the Sun), the Southern Hemisphere is tilted away from the Sun, resulting in winter (invierno). Option b (otoño - autumn) is incorrect as the seasons are opposite, not shifted by one. Option c (primavera - spring) is also incorrect. Option d (un monzón - a monsoon) is a weather phenomenon, not related to the solstice - driven seasonal change.

Answer:

a. invierno
