Yayyyyyyyyyyyyyyyyyyyyyyyyyyyyyy
From the answers given.
I would go with D, as Non-fiction isn't locked to politics or science; It's moreover use to categorize literature (books, etc...) that are based solely on fact.
Because it shares two different ideas <span />
1. would communicate
2. didn’t drive
3. didn’t work
4. would be
5. would visit
6. bought
7. took
8. would help
1. knew
2. played
3. could
4. didn’t have
5. wasn’t
Hopefully this helps a bit-
