One of the quiz questions was
The citizens choose a new president for the country.
Los cuidadanos _____ nuevo presidente para el pais.
The hint was conjugate elegir in el presente.
To make the sentence complete I typed "eligen un" for the blank, but my answer was wrong. It said the answer was "eligen". Some of the quiz questions require you to type 2 words (or more). How was I supposed to know that this specific question only wanted 1 word, which doesn't seem complete?
