As a result of dna testing, scientists learned the black death was

b, both the pneumonic plague and the bubonic plague.

Explanation: the other answer on here is wrong lol. i did this one and got it right. dont trust that other guy and also the bubonic plague wouldve been mentioned for a reason.

i do agree with robert moses’ statements about wiping out cities that are an “impediment to new growth”. in order to have a positive community, the city must continue to grow either in terms of size or economics. therefore wiping out cities that restrict growth benefits the overall society and all the people living in it. similar to a social contract, i believe that if a person was to live in a community they must sacrifice some of their rights, in this case property, for the overall good of the people. as long as these people living in the cities are reimbursed and the purpose of wiping out the cities is to serve the public, there is no problem with robert moses’ core idea.
