CThe phenomenon known as the Flynn effect suggests that average IQ scores have been rising over the decades due to various factors such as improved nutrition, education, and healthcare. Therefore, if Henrietta takes an old test, her score might be inflated (choice B) because the norms of the past would be based on a lower average IQ. However, it's also possible to argue that the score could be too low (choice C) because the test might not accurately reflect current intelligence due to changes in what is deemed relevant knowledge or skills over time. Both perspectives highlight the challenges of using outdated norms for interpreting contemporary IQ scores.
