Which of the following situations is most likely to arise when a crowded city is unable to provide its residents with sufficient sanitation? a. citizens will obtain better tenure in their housing. b. residents will suffer from preventable diseases. c. residents will experience a drop in crime rates. d. citizens will be more likely to walk or use bikes.

B. Residents will suffer from preventable diseases.

Many diseases that have been almost eliminated in large Western cities were common before the advent of proper sanitation. Crowded cities are more likely to suffer from preventable diseases if they lack appropriate sanitation measures. This is still an important problem in many developing countries.

Among the diseases that are often present when sanitation is not optimal are cholera, typhoid, hepatitis, polio, pneumonia and worm infestations.

1.3x - 2 - (3.3x + 5) = 2x + 1

1.3x - 2 - 3.3x - 5 = 2x + 1

-2x - 7 = 2x + 1

-7 = 4x + 1

-8 = 4x

x = -2
