Translation:Is there furniture for sale in the shopping mall?
Furniture is a mass noun in English and uses a singular conjugation ("is").
However, the Dutch translation ("meubels") is plural, so it uses the conjugation "zijn".
What is the difference between a shopping mall and a shopping centre. Should the both be translated as the same?
In Australia a shopping mall is quite small compared to a shopping centre. Shopping malls are usually single-level, while shopping centres are often multi-level. Most shopping centres have one or more supermarkets, while shopping malls are mostly composed of small shops. You're more likely to find franchises or chain stores in a shopping centre than in a mall which tend to be more beautique.
When I went to to Amsterdam, I visited a shopping centre. It was a very small building (by Australian standards) with only about 40 chain stores over four storeys. So the Dutch concept of a shopping centre mightn't match very closely with the Australian or American idea.
