My Gran is my hero. She is brilliant and loves to read. She also gets bored easily. As a young girl, she struggled a great deal. Because of this she ran away at the age of 21 and moved to the west coast. When she got there she chose to educate herself. She chose studies over security, as well as living in poverty. She ended up getting a job teaching at a university. She ended up marrying and having a beautiful family. Because she never stopped learning, she died with a burning curiosity about her life.
Answer: A.
singular; idiosyncrasy
Explanation: It is not B. because it is not an innumerable talent and there is not a surplus of this talent. It is not C. because it is not insular or an idiom. It is not D. because people are not disconcerted or shocked to the point where they do not know how to act and this talent is not plural. This leaves you with A. singular;idiosyncrasy because it is a talent that not many people have and it is an unusual thing about him.
Hope this helps! :)
