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 "Nikola Tesla (Serbian Cyrillic: Никола Тесла; 10 July 1856 – 7 January 1943) was a Serbian American inventor, electrical engineer, mechanical engineer, physicist, and futurist best known for his contributions to the design of the modern alternating current (AC) electricity supply system."? 

What work relates to coming up with ideas?
