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 "On 30 July 1891, at the age of 35, Tesla became a naturalized citizen of the United States, and established his South Fifth Avenue laboratory, and later another at 46 E. Houston Street, in New York. He lit electric lamps wirelessly at both locations, demonstrating the potential of wireless power transmission. In the same year, he patented the Tesla coil."? 

Where did Tesla light the lamps?
