Give a recursive definition for the set x of all natural numbers that are one or two more than a multiple of 10. in other words, give a recursive definition for the set {1, 2, 11, 12, 21, 22, 31, 32, }.

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
