Choose correct option and explain why?
___ she was 18 years old, she entered the order of the Sister of Our Lady of Loreto, in India.
- When
- As
- Since
- Whether
Well, All we know that the "Whether" is unrelated but from the book perspective, "When" is correct option. I couldn't understand? why not "As"?
Additional info:
It was one of the Konkour questions.
Konkour (Persian: کنکور; from the French Concours), is a standardized test used as one of the means to gain admission to higher education in Iran.
As you see, we don't have extra context for the question (not before and not after.), every question is independent.
