The idea being tested is how science justifies its own foundations. Scientific work assumes that the world is orderly, that our senses and reasoning are generally reliable, and that our experiments will yield repeatable results across time and space. Naturalism tries to explain everything through natural processes, but it doesn’t provide a non‑circular justification for why those preconditions—order, reliability of our cognition, and the trustworthiness of method—should hold in the first place. A Christian theistic view, by positing a rational Creator who made an orderly universe and humans in a way that makes reliable reasoning possible, offers a grounding for those very preconditions. Because of that, some naturalistic scientists find it useful or necessary to assume that theological backdrop to justify the assumptions science relies on. It’s not about whether Christianity is true or about philosophy per se; it’s about what underwrites the reliability and reach of scientific inquiry. That’s why this option is the best fit.

S-waves are shear waves, so the particles of the rock move perpendicular to the direction the wave is traveling. This transverse motion is why S-waves are often likened to waves that move a medium side-to-side, similar to how a rope or string completes a transverse wave when plucked. The statement is true because the defining feature of S-waves is this perpendicular, shear motion through solids. Ocean surface waves also involve motion of the water, but their particles trace circular or elliptical paths rather than moving strictly perpendicular to the travel direction; the key point for S-waves is the transverse displacement, which is why the comparison to transverse waves helps, and the statement holds.

Damage from earthquakes is not driven by the fastest waves. P-waves are compressional waves that move quickly and arrive first, but they usually cause less ground shaking than other waves. The most damaging motions come from S-waves and, more notably, surface waves (Love and Rayleigh waves), which travel along the ground and typically have larger amplitudes and longer shaking durations. This combination of strong motion and longer duration on the surface leads to the greatest destruction, especially near the epicenter and in soils that amplify shaking. So the statement is false; surface waves are generally more damaging than P-waves.

Warming in the Arctic shifts the calendar of life, changing when seasonal biological events happen. Plankton blooms tend to start earlier as warmer waters and increasing daylight boost photosynthesis and nutrient mixing in spring. Tundra greening follows the same pattern, with plants breaking dormancy sooner and growing longer as temperatures rise. Insects respond to temperature-driven development, so many species hatch earlier when warmth accumulates sooner in the season. Because all of these processes show shifts in timing due to warming, the best answer is that all of the above are changing. Keep in mind that the amount of shift can vary by species and location, but the general pattern is a advance in timing across these phenomena.
