Which word correctly completes this sentence? aquella falda es blanca, pero es roja.

The other person is incorrect. It should say “Aquella falsa es blanca, pero esta es roja.” The statement translates to “That skirt is white, but is red.” The other person answered “That skirt is white, but is also red.” Since it’s most likely not two colors, my answer will be correct for your assignment.

Translation is siempre en el colegio geografía y matemáticas.
