Researchers measured average bone density (g/cm²) in four age groups of women: 25-34, 1.20; 35-44, 1.18; 45-54, 1.05; 55-64, 0.92. The researchers concluded that bone density declines with age. The strongest support is ______
Which choice most logically completes the text using the data above?
- A
the 35-44 group's density of 1.18.
- Bcheck_circle
the steady decline from 1.20 to 0.92 across age groups, a drop of 23%.
- C
the 55-64 group's density of 0.92.
- D
the 25-34 group's density of 1.20.
Explanation
"Declines with age" is supported by the monotonic drop across age groups, captured by Choice B.
