Need some help with redundant expressions!!?

Question

Members of the staff and their families possesed sole monopoly over the recreation park.

thank you

Answer 1

monopoly -"mono" means "one".

sole-means "one"

sole monopoly is redundant.  Use one or the other, but not both.

Members of the staff and their families possessed a monopoly over the recreation park.

The recreation park was reserved solely for the use of staff members and their families.

Answer 2

I don't see anything redundant in here; is there something before or after it, like the rest of a paragraph?

Without knowing the context, it's impossible to answer the question.

Edit - good catch gypsy!  I was thinking repetitive words in a paragraph.  Sorry about that!
