Question

For each of the following, select the term that bests describes the type of literature it represents primary, secondary, or neither.

a. A research study from Dr. Drake and colleagues on the blood sugar levels of diabetic rats that eat only kale, compared to control diets, is published in a peer-reviewed scientific journal.
b. In the infomercial selling his own health care products, Dr. Horton states, "I believe my personal cure of daily meditation and yoga for diabetes is more effective than any drug I've ever prescribed in 20 years of practicing medicine."
c. Dr. DeBellard insists in her blog that people will lose weight in a healthy manner if they acquire some of her personal parasitic tapeworm.
d. In an article published in the Annual Review of Nutrition, a peer-reviewed journal, Dr. Pepper summarizes the last 10 years of basic research on diet and diabetes.

Answer 1

A primary source provides original research or evidence, like Dr. Drake's study, while a secondary source synthesizes previous research, such as Dr. Pepper's article. Dr. Horton's and Dr. DeBellard's statements are neither, as they lack peer-reviewed support.

Step-by-step explanation:

For each of the following, select the term that best describes the type of literature it represents: primary, secondary, or neither:

1. A research study from Dr. Drake and colleagues on the blood sugar levels of diabetic rats that eat only kale, compared to control diets, is published in a peer-reviewed scientific journal is a primary source because it presents original research findings.
2. Dr. Horton's statement in an infomercial promoting his health care products would be considered neither a primary nor secondary source; it's rather a personal testimonial with no peer-reviewed evidence to support it.
3. Dr. DeBellard's promotion of her personal parasitic tapeworm for weight loss in her blog is also neither a primary nor secondary source; it is an advertisement with anecdotal claims.
4. An article published in the Annual Review of Nutrition, where Dr. Pepper summarizes the last 10 years of basic research on diet and diabetes, is a secondary source as it analyzes and synthesizes existing research.
