Which of the following statements is considered non-testable by accepted scientific methods?

The statement regarding Hurricane Katrina as an act of God is considered non-testable by accepted scientific methods because it involves a supernatural or metaphysical explanation that cannot be empirically tested. Science relies on observations, experiments, and evidence that can be measured or observed under controlled conditions. The concept of divine intervention falls outside the realm of empirical science, as it cannot be validated or refuted through scientific experimentation.

In contrast, the other statements can be tested using scientific methods. For example, predictions about solar eclipses can be verified through astronomical calculations and observations. Bacterial resistance to antibiotics can be studied through controlled experiments that examine how bacteria evolve in response to antibiotic exposure. The Earth’s orbit can be measured and confirmed through astronomical observations and calculations as well. Each of these examples involves phenomena that can be empirically examined and analyzed, thus making them valid for scientific inquiry.
