Answer:
© "Soon they gained a reputation for working high above the ground,
because they were very coordinated." (paragraph 12)
© "They also trained themselves to deal with any fear of heights."
(paragraph 12)
Explanation:
Both of these sentences show how it takes a "special worker to do this job well". The first one shows that skywalkers had to be corrdinated to do their job and the second one shows how skywalkers trained themselves not to fear heights; both of these sentences display skills that takes a "special worker".
Hope this helps!
