Azul + amarillo + verde + rojo =

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?

Select the word from the list that best fits the definition tu madre espera que tú en casa a las ocho. sepa hagan hable estès escríbamos

8. choose the answer that best completes the sentence. (entregar) el examen. (2 points) a: entregas b: entrega c: entrego d: entregan
