Han gustado - plural agreement

Question

HI Inma I'm not sure why the answer for this is conjugated singular (ha gustado) & not plural (han gustado);Siempre me ________ leer autobiografías de gente famosa.Thank you.

Hola G
We are using the singular form of the verb "ha gustado" because the subject is an infinitive (leer ...) When there is an infinitive as the subject in a sentence with gustar, the singular form is used.
It would have been different if we had omitted the verb and said this instead:

Siempre me han gustado las autobiografías de gente famosa.
I've always liked famous people's autobiographies.

Having said that, I will add a note to the lesson as a reminder.
I hope this clarified it.
Saludos
Inma
