18. In thinking about adjective agreement and making nouns plural, how would you make the following plural: La comida popular.

O Las comida populars
O La comidas populares
O La comida populars
O Las comidas populares

The correct answer is "Las comidas populares." To make the noun "comida" plural, the article also needs to be pluralized to "las." Additionally, the adjective "popular" needs to be pluralized to "populares" to agree with the plural noun. Therefore, "La comida popular" becomes "Las comidas populares."
