"They eat butter or cheese."
Translation:Ei mănâncă unt sau brânză.
On this page, "They eat butter or cheese" is translated by ""Ei mănâncă unt sau brânză". On the previous page, however, the correct answer [to a multiple-choice question] was given as "Ele mănâncă unt sau cașcaval". I am certain that I have not seen the word "cașcaval" before. What is the difference in meaning/use between "cașcaval" and "brânză"?
