Match each sentence with its corresponding expression. A number, less six, is 1.
n + 6 = 1
The product of 6 and a number is 1.
6 + p = 1
Six more than a number is 1.
6c = 1
The quotient of 6 and a number is 1.
X-6 = 1

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
