Question

1. pedro y maria son ______.

alemanes
alemanas
alemán

Explanation:

In Spanish, "Pedro y Maria" is a plural subject (two people, one male and one female). The adjective "alemán" (German) has plural forms: "alemanes" is the masculine plural (used when there's at least one male in the group), "alemanas" is the feminine plural (used only for a group of females). Since there's a male (Pedro) and a female (Maria), we use the masculine plural "alemanes". The option "alemán" is singular, so it's incorrect.

Answer:

A. alemanes
