The goal of naturalistic observation is to:
1. test hypotheses formed prior to the study.
2. conduct research in experimental rather than real environments.
3. get quick answers to theoretical questions.
4. provide a complete and accurate picture of what occurred in a setting.

Option 4

Explanation:

Naturalistic observation is q type of observation that involves observing a particular event how it happened naturally, without using any testing method to get, the research has to note down how the stages in this effect happened until the whole picture is understood . Relating the explanation I have above, option 4 explains more what naturalistic observation is , as it is to create the accurate picture of a setting that is the main goal of naturalistic observation.

the answer would be in this answer. someone already asked the question.  

this statement is true.

forests are public goods, available for everybody. when usage of such a good becomes interesting for consumers and its usage increases, there can be a risk of overexploitation. it is a non rival good therefore, if one person consumes the good it does not reduce the availability for subsequent consumers.

these caracteristics require the establishment of measures in order to prevent the destruction of a commonly owned space, for example, to restrict the amount of people that have access to the same time.
