Why? Because Duo's preference is favorite. Preferred could be an alternative translation, after all, Spanish does have a word for favorite. ¿Cuál es tu comida favorita?
Check a dictionary. The English translation of the Spanish word preferido is favorite. In Spanish, favorito and preferido are interchangeable.
Yes, preferred is a better translation here. Remember everyone, if you are relatively sure it should be accepted simply report it. No need to down-vote the sentence or add multiple comments on it. This just clutters things up. I believe these are relatively newly added sentences so the data bank for accepted answers is not large. Reporting correct answers will help with this.
And how did you make it blue writing? Did you make it up? I'm sorry to"shower"you with sooooooooooooo many questions!
Just copy the website's URL and paste it into the reply box. It will turn blue on its own.
What is the deal with this series of questions rejected 'preferred' when asked to translate 'preferido'? Someone dropped the ball big time when they programmed in the valid translations.
Now accepted: "which is your preferred food" Remember folks, don't complain when you know you are right. Just let Duo know in the "Reply" feedback :) They DO listen...
I put "What food is your favorite" and was marked wrong. It the placement of food so important?
"What is your favorite food," and "what food is your favorite" are similar but distinct questions. The former is a faithful translation of the Spanish sentence, while the latter is not.
