Because Mr. Dunham always wanted an opportunity to work with animals, he decided to volunteer at his local animal rescue shelter on Saturdays. However, there is a requirement that all part-time volunteers work at least one evening a week. He's not sure that he can meet this obligation because he often works late at his job. He hopes that the shelter might make an exception in his case. Underline words - A) opportunity, B) requirement, C) obligation, D)exception

Clarification:

I found the complete instructions for the exercise online:

"Read the paragraph. Click or tap Two underlined words that are synonyms."

B and C: requirement and obligation.

Explanation:

To complete the exercise, you have to select the words that are synonyms. The correct answers are "requirement" and "obligation" because a requirement in a job offer is something that is required, that is needed, to get the job, so it is a synonym to obligation, something you are demanded to complete or to accomplish.

i believe it is "he will always remain extremely timid" if its wrong sorry
