electrons transfer from a material that holds electrons less tightly to a material that holds electrons more tightly
the terminology used in this is very unscientific. be aware of that.
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!
