Question

1. mis hermanos son ______

○ alemanes
○ alemán
○ alemanas

Explanation:

In Spanish, "hermanos" is masculine plural, so the adjective describing nationality should also be masculine plural. "alemán" is singular masculine, "alemana" (feminine singular) and "alemanas" (feminine plural) don't match the gender and number of "hermanos". "alemanes" is masculine plural, so it's the correct choice.

Answer:

alemanes
