for multiple choice, i got:
1. b
2. d
3. c
4. b
5. a
6. d? i thought a wasn't specific enough with "people" and d mentions "all" people so maybe that's why?
7. c
8. a
9. c? i think investigating properties is much more reliable than secondary research
10. b
so stoked someone got similar answers! i hope everyone did well x
