Answer
The rapid increase in obesity over the past 30 to 40 years is likely due to changes in the environment or environmental contexts.
Solution
a
Genetic makeup: The genetic makeup of a population does not change significantly over such a short period (30 to 40 years). Therefore, it is unlikely that the increase in obesity is due to genetic changes
b
Environment or environmental contexts: Changes in lifestyle, diet, physical activity, and other environmental factors are more plausible explanations for the rapid increase in obesity
c
Exosystems of families only: While family environments can influence obesity, focusing solely on exosystems of families does not account for broader societal changes
d
Microsystems of children only: Similarly, focusing only on the microsystems of children does not provide a comprehensive explanation for the widespread increase in obesity
Key Concept
Environmental factors
Explanation
The rapid increase in obesity is more likely due to changes in environmental factors such as diet, physical activity, and lifestyle, rather than genetic changes or limited family and child-specific contexts.
