Answer:
b) C and F
Step-by-step explanation:
Although all these sentences clearly help us imagine the wealth of the residents of Pompton Clewes, they also differ in one way; some of them are completed, provide us with enough information or using comparison to help us paint a full picture, while some of them lack details to help us imagine all the glamour of the houses.
Sentence C, for example, "The houses were designed for maximum space and luxury" does not give more details and descriptions of that design, leaving the readers unable to imagine such house.
Alsi, sentence F, ”Yards clearly enjoyed the care of professional gardeners", in the similar way as the previous, only tells us that the yards enjoyed professional care, not explaining what that means or hiw do they look.
