qualitative research
Explanation:
Richard, a research scholar, wanted to do a research study in a subject which does not have a lot of preexisting knowledge. SO he will have to ask basic question to his research subjects in order to get an overall idea about the topic. By doing such he will be able to gain a basic knowledge about the subject he had chosen.

Environmental conditions generated regional differences in food, crops and culture.
Explanation:
Each region had different environmental conditions, such as climate and soil type and fertility. This makes the crops, crops and food produced in each region consistent with the environmental conditions in each region.
We can use the apple as an example. The apple is a crop that requires cold weather, deep soil, with high fertility and long days, for example. In this case, apples should be produced in states that had this type of environmental condition, but these conditions were not seen in all states. In this case, the states that did not have the necessary environmental conditions for the apple, planted other crops.
The climate and duration of the day and night also caused changes in the day of harvest and harvest of each culture in each state.
