"The pandas are black and white."
Translation:Gấu trúc màu đen và trắng.
Sorry, I took your comment as an objection for the use of những, but now I understand you back me up. I am the student, so I can only say how I understood it. By not using the classifier, the sentence is made general. But in that case the article should not be used, just pandas in general. By using the article I think những should be added. But I give my opinion for a better one.
