Answer:False 
Explanation: There are various types of pollution and not all of these are restricted to cities. 
For example pollution may result from improper disposal of waste and this is very likely to also occur in rural areas where you find that people may just dump waste on the rivers and lakes which in return affect activities such as fishing and swimming. Even the industrial water which may be dumped from the cities will still be carried away by rivers to reach other areas away from the cities. Nutrient pollution also comes from rural areas where there is a lot of farming happening and a high use of fertilizers , pesticides and herbicides which also have an impact as they get washed into the rivers and impact the quality of water such that the water becomes undrinkable.
So pollution is everywhere and there are different kinds of it.

Answer:a.Naturalist
Explanation:
A naturalist believes that subjects or participants are able to show their original behavior if they are in their natural environment. A researcher would be more likely to get a true presentation of the participants behaviour if they observe them in their natural environment, if they are not aware that they are under observation. People act normal in normal situations but may alter their behaviour in situations when they know they are being watched.
A naturalist will carry those experiments or research that can't not be done in a lab such as this one of observing women in a shelter.
 
        
             
        
        
        
President Andrew Jackson on his Seventh Annual Message to Congress dated December 7, 1835, concerning the Indian Removal Act, saying, <span>"No one can doubt the moral duty of the Government of the United States to protect and if possible to preserve and perpetuate the scattered remnants of this race which are left within our borders. In the discharge of this duty an extensive region in the West has been assigned for their permanent residence. It has been divided into districts and allotted among them. . . .".</span>
