Question

the carbon stored in rocks such as limestone recycle through the system __.

• neither quickly or slowly
• very quickly
• very slowly

Explanation:

Carbon in rocks like limestone is part of the slow carbon cycle. Geological processes involved in recycling this carbon (e.g., weathering, sedimentation, metamorphism) take a long time (millions of years), so it recycles very slowly. The other options are incorrect: "neither quickly or slowly" is ill - phrased and not accurate, and "very quickly" goes against the known geological timescales for rock - based carbon cycling.

Answer:

C. very slowly (assuming the options are labeled A, B, C as neither quickly or slowly, very quickly, very slowly respectively)
