Is the following example correct, as I want to add an "un"?

 "Se vende apartamento de lujo en la playa. A luxurious apartment is for sale at the beach." 

Hi, I'm doing the quiz and ¿Usted lo ________ ? is the question - the correct answer is listed as comprende however the phrase can you understand it? is second person not 3rd so wouldn't comprendes be correct?

Hola, 

I'd like to know in this sentence, whether we should use "menor" or not:

La familia actual se ha reducido, el numero de hijos cada vez es menor? menos?

Muchas Gracias!

If querer que is a subjunctive because it expresses wants, why is the negative also subjunctive? It expresses "not wants". Or is it because that technically also counts as a want? I remember reading that if you have a negative of a subjunctive it becomes an indicative

I stumble over pero, sino que and sino and the following example is a good one to drive me crazy. 

Elia no va a empezar el curso este año ________ va a tener un año sabático.

Pero vs Sino Que. 

For the example above both „pero“ and as weln „sino que“  were flagged as correct  and wrong in Kwiziq! 

I have checked the rules more than once and verified that with OpenAI, Mistral AI, Claude, etc and all came across with rules and explanations and all of the AI explained to use pero and when I asked again they said use sino que. So it would be nice to get your answer on it and to correct and remove the wrong answers. 

Thanks,

Bernd

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.
