What phrase would be associated with the time most people eat breakfast?

mediodía
por la mañana.
medianoche.
por la tarde.

Mediodía means middle of the day
Por la mañana means morning
Medianoche means middle of the night
Por la tarde means afternoon

Therefore, por la manana is the correct answer. Unless everyday of your life you always forget to have breakfast in the morning... xD

For this question, it will be important to use the words "mejor" (better), "lo mejor" (the best), and "lo peor" (the worst). while "mejor" is comparative (you are comparing one thing to something else), "lo mejor" and "lo peor" are superlative (there is nothing else better or worse than what these words are describing - there is no comparison).  you could say something like: la música rap es mejor que la música clásica - que es lo peor - pero la música rock es lo mejor de todas las formas de la música (rap music is better than classical music - which is the worst - but rock music is the best out of all the forms of music).
