When providing GRE examples in the writing sections, how vague is too vague? Do you need specific names and statistics? Here is an example:

Prompt: Governments should place few, if any, restrictions on scientific research and development.

Sentences I wrote supporting my point that no restrictions on research could lead to biased research ultimately harming the public:

One example of biased research is how major dairy corporations funded research to find health benefits of milk, leading to advertisements such as the “Got Milk” campaigns seen in magazines and on billboards. These advertisements asserted that milk is a necessary part of the human diet. However, other researchers determined that diets high in dairy could lead to high blood pressure and heart disease.

-I am wondering if using “major dairy corporations” or something like “researchers found”, without naming the specific research is too vague?

-Also, are the scorers fact checking? Meaning, could I insert some random name to serve as the researcher and that would benefit my score?
