Video Summary

To prevent the mouse from reaching the cheese, two out of five gates must be closed. The solution is identified through a process of elimination and tracing paths backwards. Closing gates one or two does not stop the mouse effectively, as the mouse would already be near the cheese before reaching these gates. Similarly, gate three is ineffective as it leads to a dead end. However, closing gates four and five effectively blocks the paths to the cheese, ensuring the mouse cannot access it. Thus, gates four and five need to be closed, making the answer E.
