I learned that one only puts accent marks on the question words in Spanish when they are in an actual question. When used in a statement, no accent mark is required. So, "¿Cuándo llamaste a tu madre?" But, "Cuando llamo a mi madre, siempre le digo "te quiero.'" In Level 4, lesson 3--Write the Phrases you Hear, I couldn't get credit for this answer until I put the accent mark on the "a" in cuando: "La verdad es que no sé cuándo voy a volver a Europa, pero quisiera visitar París." I don't understand why the accent mark is needed in that statement unless it's because the structure of the statement implies a question about returning to Europe.

I am working in Level 3 of the updated platform. The color combination in the Pick the Right Answer Workout makes it difficult to read both the statement and the answers, but it is especially hard to read the 3 possible answers. If the words were in white instead of black, that would help a lot; or perhaps just a completely different color combination would be more appropriate.
