Answer:
Columbian Exchange
Explanation:
The Columbian Exchange refers to the period where there was a widespread transfer of plants, animals and culture between the Americas and Europe.
This exchange was named because of Christopher Columbus who was the Spaniard who first arrived to the Americas (while trying to find a new route from Spain to India) and started the maritime route from Europe to the Americans, starting a process of exchange of plants and animals among other things.
This exchange took place mainly during the 15th and 16th centuries.
Answer:
No
Explanation:
The journalists asked people about their own personal experience with herbal supplements, therefore, it relies on what people say and on their anecdotal evidence.
We say that a research is reliable if the method used produces stable and consistent results. In other words, if we apply the same method on similar objects/subjects it will produce the same results.
In this example, this survey is based on the participants "own experiences" and therefore the journalists shouldn't be able to reliable conclude anything that actually establishes a relation between herbal supplements and depression. They would need a hypothesis, a control case study and more controlled observations rather than a survey.
