I don't understand what number 5 is doing in this quiz, since it has nothing to do with science and there is no correct answer.

The largest city in Pennsylvania is Philadelphia, not Pittsburgh (note spelling), measured in population as well as area. The 2010 census estimated the population of the city of Philadelphia at 1,526,006; the metro area population is 5,965,343. The area of the consolidated city-county of Philadelphia is 142.6 square miles. The 2010 population of the city of Pittsburgh was 305,704 (metro area 2,356,285). The area of the city is 58.3 square miles. Besides 'Pittsburgh,' there are a number of other spelling errors and you used 'and' where 'can' should have been used. Thanks for your attention :)
