Scientists found that shorter, stockier types of wheat and rice soak up about half as much toxic arsenic from the soil as the tall, slow-growing kinds—so breeding these shorter crops could help people in dirty areas eat safer food.

Assessment Explanation
The claim describes an observed association between plant architecture (dwarf/short-duration) and reduced arsenic accumulation, which is supported by field and greenhouse studies comparing cultivars. It does not claim causation or mechanism, only that breeding can reduce exposure—a reasonable inference from correlational data. The use of 'suggesting' is appropriately cautious. However, 'approximately half' is quantitative and should be backed by meta-analyses across multiple environments to be reliable.
More Accurate Statement
“Short-duration and dwarf wheat and rice cultivars are associated with approximately half the arsenic accumulation in their grains compared to tall, long-duration varieties, suggesting that crop breeding may help reduce dietary arsenic exposure in contaminated regions.”

Evidence from Studies
Supporting (1)
Scientists found that shorter, stockier wheat and rice plants soak up less arsenic from the soil than taller, slower-growing ones, so planting these shorter varieties can help people eat less poison from their food.
