Buenas tardes! necesito ejemplos de palabras con acento diacritico y palabras sin acento

Is anyone able to ? i am so confused. this sheet is about irregular preterit verbs and direct object pronouns in spanish.

Okay so i'm taking an online spanish course (penn foster), and in the study guide, you have to create a bunch of sentences with words you've learned so far. translating, reading, and those kinds of things are fairly easy, but when it comes to making my own sentences, my brain just kinda waltz's away. anyone got any tips?

Which phrase best completes this sentence? en los almacenes están al aire libre. a. el supermercado b. el mall c. la feria artesanal d. la librería
