Answer:
between-subjects design
Explanation:
According to my research on different experimental designs, I can say that based on the information provided within the question the best way to make sure that the internal validity will not be influenced by an outside event is to switch to a between-subjects design. This type of design is an experiment design that has two or more groups of subjects each being tested by a different testing factor simultaneously. Since they are done simultaneously it significantly reduces outside influence.

The food you eat can affect your health and your risk for certain diseases. To eat healthier food, you may need to change some of your daily habits. You also may need to change some things in your environment. Your environment includes everything around you, like your home or the place you work.
You don't need to make huge changes to eat healthier. And you don't have to change your habits all at the same time. It's best to set small goals and change your habits a little bit at a time. Over time, small changes can make a big difference in your health.
