Answer:
D) My sister, who exercises every day, is coming over for dinner.
False.
Word roots are found at the beginnings of words, with affixes being added either in front of it or after it, suffixes after and prefixes before.
The simple subject would definitely be "Many" because these "Many" are the people do something, which leads us to the predicate. The simple predicate would be "were sent" or "sent" because that is what the "Many" were doing (technically they were forced).
