I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "18th Street has a local subway station at the crossing with Seventh Avenue, served by the 1 2 trains on the IRT Broadway – Seventh Avenue Line. There used to be an 18th Street station on the IRT Lexington Avenue Line at the crossing with Park Avenue South."? 

What does 18th Street connect to?
