Question

the graph indicates the prevalence of obesity among children and adolescents in the united states from 2009 to 2010.
prevalence of obesity among children and adolescents
age in years: 2–19, 2–5, 6–11, 12–19
which inference can be made about this data?
a large difference in obesity diagnoses exists within the male group.
healthy eating habits should be encouraged and implemented early in life.
obesity is much higher in teenage girls than in teenage boys.
(note: the last option is partially obscured but the main question and options are as above with the chart showing obesity prevalence by age group (2–19, 2–5, 6–11, 12–19) for all, boys, girls with percentage values.)

Explanation:

• For option A: The male group (Boys) has obesity percentages (18.6, 14.4, 21.1, 19.6) with relatively small differences between age groups, so no large difference within males. Eliminate A.
• For option B: The graph shows obesity prevalence in children/adolescents, so encouraging healthy eating early (to address obesity) is a valid inference.
• For option C: Teenage girls (12 - 19: 17.1) vs boys (12 - 19: 19.6) – boys have higher obesity, so C is wrong.
• For option D: Teenagers (12 - 19) have significant obesity percentages (19.6 for boys, 17.1 for girls), so they don't have minimal risk. Eliminate D.

Answer:

B. Healthy eating habits should be encouraged and implemented early in life.
