Question

Pensez-vous que les fantômes existent ? - Oui, nous ________ pensons.In the quiz, why is the answer 'le' instead of 'y'. I thought it was 'penser à quelque-chose'.

Bonjour Roshni,
"To refer to previously mentioned ideas, opinions and statements, in French you use the neuter pronoun le (or l' in front of a vowel or mute h)."
From the lesson text above  -- I'm a bit puzzled by your query.
Pensez-vous que les fantômes existent ? - Oui, nous ________ pensons. Yes, we think it or that (le) to be the case.
I see this as fitting into the "ideas, opinions and statements" as the lesson states.
I hope I'm understanding your query accurately?
Bonne journée
Jim
