Will mark brainliest!

I'm doing a Roller coaster project for Algebra 2 and am needing some assistance. I've posted an attachment of what it should look like. All I need is three equations so I can make the coaster. Any help is appreciated. Thank you in advance. (You can't use the same equations given in the example)

step-by-step explanation:

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
