What are the four main differences between the old and new frameworks for evaluating the effects of logging on floods? (Select all that apply.) 多项选择题

The old framework pairs floods by the same storm, while the new framework pairs floods by the same frequency.

The old framework evaluates changes in flood frequency, while the new framework evaluates only changes in flood magnitude.

The old framework uses pre- and post-regression, while the new framework uses pre- and post-flood frequency distributions.

The old framework relies on uncontrolled experiments, whereas the new framework uses controlled experiments.

The old framework focuses on landscape-scale processes, while the new framework focuses on stand-level hydrology.

The old framework is deterministic, whereas the new framework is probabilistic.
