PTB.S4.Q25 - Some residents of Midville claim...

Hi everyone! I just took five practice questions and for PT B, section 4, question 25. If anyone has this question open or has worked on it recently, I'd greatly appreciate the help!

I selected D but the answer choice was A, I'm not understanding how the answer ended up being that both towns are comparable in living cost/price. How is this the main point?? Thank you very much in advance :)
