Answer:
Without longer school recess, kids will continue to be obese.
Step-by-step explanation:
A bias can be defined as a tendency, inclination, opinion, or prejudice toward or against something or someone. Biases are usually not based on actual knowledge.
An example of a biased statement is the fourth one: Without longer school recess, kids will continue to be obese. It's based on an opinion. We don't know if longer school recess will lead to fewer children being obese. There's nothing to support this claim.
The rest of the statements are based on facts. The first statement mentions a study, the second statement is a fact, while the third includes a recommendation based on science.
