13. Bir kırtasiyeci 92 defteri 4lük pa-
ketlere yerleştirdikten sonra her paketi
18 TL'ye satmıştır. Kırtasiyeci bu satış-
tan kaç lira gelir elde etmiştir?​

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3

the answer is 9 because the question is telling how much it be together.
