Is this Vista Learning? Do you know what course is it? And how I can get there? Thank you!:)

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?

Timoteo es de guinea ecuatorial. el

Which verb form best completes this sentence? pablo picasso el estilo de cubismo. a. invente b. inventaste c. inventó d. invento
