the article says:
riders zip around the loop so fast that it can feel like they are lifting off to space! what causes this? sprayers make the tube super slick. so, riders can keep sliding along.
which means almost the same as slick?
a. safe
b. slow
c. special
d. slippery

Explanation:

The word "slick" means having a smooth surface that causes things to slide easily. "Slippery" has a similar meaning, referring to a surface that is difficult to grip or stand on because it is smooth. The other options "safe", "slow", and "special" do not have a similar meaning to "slick".

Answer:

D. slippery
