Victoria Harding · Answer 1

The data about the nutrition of fast food is inaccurate.

Explanation:

Although the scientist has the report of many professionals about the influence of fast foods on obesity, the data on these foods in this research are inaccurate for the scientist to be able to draw a conclusion. This is because the scientist does not demonstrate what factors make eating through fast foods influence obesity, the scientist does not show the composition of these foods, nor how they act on the human body and how this is associated with exacerbated weight gain.
