A student wants to use this excerpt from a source in a research paper but is concerned about bias. Which two statements in the text imply author bias? Gentrification has been a very controversial topic since the World War II era. Gentrification starts when developers come to prime areas in a city that are close to downtown areas, recreational places, and public transit with the intention of mowing down older homes on huge lots to construct overly expensive townhomes. Some argue that gentrification increases economic opportunities and revitalizes the look of many neighborhoods. They say that gentrification attracts people from other states, further boosting the economy and increasing diversity. But none of the people displaced by the increase in property taxes due to gentrification can enjoy these economic opportunities.
