To determine if sugar-rich diets affect hyperactivity in kids, a researcher prepared two daily menus that children would receive for a 30-day period. A high-sugar diet was given to the boys, while the girls had a menu that seemed identical but was not a high sugar diet. At the end of 30 days, the boys and girls were evaluated to determine their levels of hyperactivity. In the study, the high-sugar diet is the ________.
A) placebo
B) independent variable
C) dependent variable
D) control group
High-Sugar Diet
A diet consisting of a high proportion of sugars or carbohydrates, which may affect health negatively by increasing the risk of obesity, diabetes, and other conditions.

Final Answer :
B
Explanation :
The high-sugar diet is being manipulated by the researcher, so it is the independent variable. The hyperactivity levels of the children are being measured as a result of the diet, so it is the dependent variable. A control group is also typically used to compare the effects of the independent variable, but it is not mentioned in this scenario. The menu given to the girls is not a true control group because it is not identical to the high-sugar diet in all aspects except for the sugar content. Therefore, the answer cannot be D or A.
