When she served as a state senator, grandmother still lived on Thirty-first Street. Hope this helps! This is the correct answer because you cannot have a second letter capitalized in one word. And the street part of the location is part of the name, so you need the beginning of all the words capitalized.
the answer is: When she served as state senator, grandmother still live in Thirty-first street.
The sentence that uses correct capitalization is A: "When she served as a state senator, Grandmother still lived on Thirty-first Street." It correctly capitalizes 'Grandmother' as a proper noun while keeping 'state senator' in lowercase, as it does not precede a name. 'Thirty-first Street' is also correctly capitalized as it is a specific street name.
