#1- The chart shows an increase over each decade. This means it is option B. We can come to this conclusion by looking at the rise of the dates and population number.
#2- The chart shows a dramatic increase. By eliminating all of the other options due to the fact everything increased and not the opposite, the answer must be B. We can also look at the left side of the chart to see the number of people living in New York increasing by more than two million.
#3- The picture clearly shows the idea that urbanization led to more Americans who preferred city living in the 1800s. We know from the charts that more people moved to New York during the 1800s, we can also see a lot of buildings in the picture. This leads me to conclude the answer must be B.
#4- Looking at the picture I believe the answer is A. I do not see the difference between residential or business areas, the water level, or the amount of trade being conducting. This leads me to conclude that A is the only correct option.
#5- I do not know this answer due to the lack of readable context and the fact that I do not take your course. I would need a date.
I hope my time and effort suffices your quench for knowledge. Have an amazing day and never stop learning! :)
