When the british system of units was first developed, what was the most
common object used as a basis for measuring length?
a. the human body
b. automobiles
c. the king's castle
d. animals

yes

step-by-step explanation:

yes

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
