I was so confused on #7 because I thought it was saying the CHARACTERISTICS were discussed in paragraph 2 not the PAINTERS. I was like where in paragraph 2 does it mention these? Lol

I got it right but B tripped me up bc exposure to allergens in infancy (or at least peanuts lol) can reduce your chance of developing the allergy. In that case, B could kind of be supporting the stimulus because it would be saying that even though children in small families were less likely to have allergies due to being exposed to allergens young, children in large families were still less likely to develop allergies bc of exposure to germs.
