Final answer:
Casual dining, also known as family-style dining, involves communal serving dishes placed at the center of the table. For an unbiased study on fast food's impact, researchers should not accept funding from fast-food restaurants due to potential conflicts of interest.
Step-by-step explanation:
The style of dining also known as family-style dining is casual dining. In this style, food is often placed in serving dishes in the center of the table, and diners serve themselves. It fosters a homely atmosphere where diners can interact freely and share dishes, somewhat reminiscent of eating at home with family.
To answer the additional reference question, to study the effects of fast food on lifestyle, health, and culture, a researcher ethically should not accept funding from a source that has a vested interest in the outcome of the research, such as a fast-food restaurant. Accepting such funding could lead to a conflict of interest and compromise the integrity of the research.
