Another question that is common relates to processed meat products. Once a processed meat product (ham, hot dog, lunchmeat, etc.) package is opened, the product should be good for up to seven days unless another type of date is on the package and has passed. After the seven days, the product should not be consumed.
Primary research is any type of research that you go out and collect yourself. Examples include surveys, interviews, observations, and ethnographic research. A good researcher knows how to use both primary and secondary sources in her writing and to integrate them in a cohesive fashion.
Original research is considered a primary source. An article is considered original research if... 1  it is the report of a study written by the researchers who actually did the study. 2  the researchers describe their hypothesis or research question and the purpose of the study. 3  the researchers detail their research methods.
