I want to know the answer to the following question:
What type of vacant buildings have been spared destruction?
All the background I'm provided with is that "The city of Detroit and other private-public partnerships have attempted to catalyze the region's growth by facilitating the building and historical rehabilitation of residential high-rises in the downtown, creating a zone that offers many business tax incentives, creating recreational spaces such as the Detroit RiverWalk, Campus Martius Park, Dequindre Cut Greenway, and Green Alleys in Midtown.". Is that enough to answer the question?
Answer: no
