Hello everyone! Could someone explain me which mood should be used with the expression “no es posible que”? In the grammar section I have found information that this phrase expresses certainty similarly to expressions such as “es claro que”, “es cierto que”. That’s why when I came across the sentence “No es posible que Miguel (ganar) a Paco” in the quiz I have selected a verb in an indicative mood. However, it appeared a red box signalling that I was wrong and that subjunctive should be chosen. Their explanation went as follows: [Lo siento. Incorrect. From the speaker's perspective, "Miguel gane a Paco" is not in the realm of possibility. Therefore, the subjunctive is required to express this "contrary-to-fact" statement.]
I’m confused now. I will appreciate help of Spanish advanced speakers or natives. Thank you in advance!
