The volume of this figure is 660 cube centimetre
66mm=6cm
So that means that any 66mm is 6cm point 6mm ===> 66cmm=6.6cm
Thus, 6cm is not greater but it is equal to 66mm
It's like you looking at 1yd=3feet which also means that 3feet=1yd.
The answer is letter A.
In the paragraph, only 20% of the customers who voted highly returned. From this, we can only say that some of those people came back. Most means a majority of the population and some means a minority.
Also, we can't say C or D because we do not have any information regarding customers who voted badly. C says that high rating make people come back, but we do not have any information on the people who voted mediocre. We can not say C. D says that customers who come back will be high rating customers. We do not know if any customers who voted low came back, so we are unable to say D.
