Він повинен працювати в центрі Чикаго

Answer 2

It looks like there might be a typo in your sentence. It seems to be missing some words, making it unclear. However, I assume you are trying to say: "He will work in the center of Chicago."

If that's the case, then it means that "he" will be working in downtown Chicago or the central business district of the city. The center of Chicago is a bustling area with many offices, businesses, restaurants, and cultural attractions. It's a popular location for work and entertainment, with easy access to public transportation and various amenities.
