Alfredo ________ un mes en recuperarse de la neumonía. It took Alfredo a month to recover from pneumonia.
Choices: le demoró, le tardó, se demoró, or tardaron
I don’t understand why the correct answer is se demoró. Alfredo is the subject of the sentence and it is in the past tense so tardó or demoró should be fine. The lesson does not say not to use the indirect pronoun “le” and it also only talks about using “se” for transportation and for general things. Can you explain this to me? Thanks.
