Answer:
Las palabras que llevan acento son: fácil, lección y rápido.
Step-by-step explanation:
The words who have accent mark are: fácil, lección y rápido. Rápido is a word that in Spanish is called "esdrújula" and they always have an accent mark in the antepenultimate syllable. Lección is a word that in Spanish is called "aguda", which means its accent is in the last syllable. If they end with an n, an s or a vowel they always have an accent mark. Finally, fácil is a word that is called "grave". The words that are graves have their accent in the penultimate syllable, and they have an accent mark if they don't end with an n, an s or a vowel.
