The main way that the infectious liver disease hepatitis C is spread is through contact with the blood of an infected person.
It can all be spread by sharing needles or other drug paraphernalia, receiving a contaminated blood transfusion or organ transplant (before widespread testing), or working with blood in medical facilities. Although the risk is generally seen to be lower than for other sexually transmitted viruses, hepatitis C can still be transmitted through sexual contact, even though the predominant mechanism of transmission is blood-to-blood contact. The risk of sexual transmission can be reduced by precautions, including the use of barrier techniques.

Answer:In the scenario described, the explanatory variable is the independent variable, and the response variable is the dependent variable.
Explanatory Variable: The explanatory variable is the one that the researchers manipulate or control to see its effect on the other variable. In this case, it is whether or not the participants eat oatmeal. Team A asks participants to record how many days they eat oatmeal for a month.
Response Variable: The response variable is the one that the researchers measure to see how it is affected by the explanatory variable. In this case, it is the participants' blood cholesterol levels. Team A measures the participants' blood cholesterol levels at the beginning and end of the month.
Now, regarding whether Team A is conducting an experiment or an observational study:
Experiment: An experiment involves actively manipulating an explanatory variable (in this case, the oatmeal consumption) and observing its effect on the response variable (blood cholesterol levels). In Team A's case, they are actively instructing participants to eat oatmeal for a certain number of days and then measuring the impact on their blood cholesterol levels. Therefore, Team A is conducting an experiment.
In summary, Team A is conducting an experiment to investigate the relationship between oatmeal consumption and blood cholesterol levels. They are actively manipulating the explanatory variable (oatmeal consumption) and observing its effect on the response variable (blood cholesterol levels).
