Hello. I'm a "newbie" and I hope I'm following the rules! Could someone please tell me if the structure of this sentence (particularly the subject/verb agreement) is correct? El Mural de Los Bebedores es el mejor ejemplo de los espacios pictóricos donde se manifiesta que fue producto de una sociedad que respondía al momento en que se realizaron. I've translated it as The Drinkers Mural is the best example of Cholula’s pictorial works, and it demonstrates that these pictures were produced by a society that responded to them at the time they were painted. I added the "and it demonstrates" because the only singular subject was "The Mural" but it seems that it ought to say "que FUERON productos" to agree with ESPACIOS. Thanks in advance for any opinions!
