11. D
12.C
13. For 13 i would say B but not so sure
14. A
Hello!
This is a difficultly easy question, mostly because it seems like all of the answers would be right, but if I had to choose one, I would say (D) because this option gives the most detail.
Option A only tells us how fast a car was moving
Option B only tells us the rate the water falls and how fast it is going
Option C only tells how far and not the speed or destination
Option D is correct, it tells us the speed/rate, the destination, and what is moving
Therefore, Option (D) is correct
If this helps, please mark brainliest, have a great day!!
Opioid's tend to show during runners high, so my guess would most likely be dopamine
