Our cat, margo, disappeared for two days last week. our cat, margo, came back with six baby kittens.
which combines these two sentences to express the same idea? check all that apply.
our cat, margo, disappeared for two days last week, and she came back with six baby kittens.
margo, our cat, had six baby kittens after she disappeared for two days last week.
after disappearing for two days last week, our cat, margo, came back with six baby kittens.
margo, our cat, had six baby kittens, but they disappeared for two days after she came back.
six baby kittens disappeared for two days last week after our cat, margo, came back.

"After disappearing for two days last week, our cat, Margo, came back with six baby kittens." and "Our cat, Margo, disappeared for two days last week, and she came back with six baby kittens." (sentence 1 and sentence 3) both express the same ideas as the original two sentences. The other three are faulty in the following ways:
Sentence #2 implies that she had the kittens herself, which is not actually stated in the original two sentences. 
Sentence #4 implies that it was the kittens who disappeared, which is not stated in the original two sentences. 
Sentence #5 again implies that it was the kittens who disappeared, and that they disappeared after Margo came back, which is not what the original two sentences indicate at all. 
Hope this helps!
