It is asking how physical living conditions affect your way of life. Your surroundings determine lots of factors in your life, basically.
I believe the answer is b. Tomas can decorate 16 gifts with 2 rolls of ribbon because you divide 34 into 2 and you get 17. and since you want to use all of the ribbon the best choice is 16 gifts. Btw plz don't report me if i get this wrong.
Hope this Helps!
