Explanation:

For question 3: The Panama Canal generates revenue via tolls from ships transiting it, which directly contributes to economic development. The other options are incorrect: the canal does not aid crop growth, did not expand forests, and did not stop all pollution.
For question 4: The construction of the Panama Canal required clearing large swathes of forest for the canal route and related infrastructure, causing deforestation. It did not increase earthquake activity in the region.
