Question

Which is an example of pseudoscience?
use of X-rays to observe the bones of the arm
use of DNA analysis to determine paternity
use of vaccines to prevent the occurrence of disease
use of astrology to predict the personality of a child

Answer 1

Use of astrology to predict the personality of a child.

Reason: astrology lacks empirical support, testable mechanisms, and reliable predictive power, so it's considered pseudoscience; the other examples are evidence-based scientific practices.
