Flowing rivers, can be found in areas away from karst topography.

The correct statement among the given options about the process of scientific inquiry is "It is possible to test hypotheses, such as those involving historical events, without conducting experiments."

Although it is not possible to carry out experiments to test hypotheses about evolutionary relationships between living groups or about the timing of the origin of major evolutionary innovations, such hypotheses can be evaluated by making predictions about the expected findings that would result from these hypotheses. Data can then be collected to test whether these predictions are correct.
