Which of these sentences uses the word requisite correctly?
1. the emperor was known for his courageous and requisite spirit.
2. the wettest region on earth receives requisite showers.
3. nikita didn’t get the job because she didn’t possess the requisite skills.
4. jennifer was profusely apologetic for her requisite behavior.

Hello, the definition of the word requisite is: made necessary by particular circumstances or regulations. Therefore, in a sense, you can think of the word requisite as 'necessary'. If you look at your choices, replacing 'requisite' with 'necessary' shows that the choice that makes the most sense is 3. That is because it makes sense to say that Nikita didn't get the job because she didn't possess the 'necessary' skills. Meanwhile, in all the other choices, the word necessary doesn't quite fit. After all, it doesn't quite make sense to have a necessary spirit or necessary behavior :)
