Answer:
Statement 2, 4, and 3
Step-by-step explanation:
Statement 2 is true: precipitation, such as rainwater, is the primary source of freshwater on Earth.
Statement 4 is true: human activity, such as taking a bath, can change the quality of a freshwater resource.
Statement 5 is not true: pollution in lakes can affect groundwater because the ground does not act as a barrier or filter to stop pollution from seeping into the groundwater.
Statement 1 is not true: rainwater alone cannot replace or replenish freshwater sources if there is a long-term drought, as rainwater can be insufficient to offset the loss of freshwater. Statement 3 may be true in areas that have aquifers or shallow groundwater systems, as an increase in surface freshwater may lead to an increase in groundwater recharge. However, this will depend on the specific hydrogeological conditions of the area, so this statement is not universally true.
