Step-by-step explanation:
Presidents typically receive their highest approval ratings during periods of national crisis or significant events. These events can include things like a successful military intervention, a national emergency, or a major achievement. For example, George W. Bush's approval rating spiked to 86 percent after the 9/11 attacks, and Barack Obama's approval rating increased after the killing of Osama bin Laden. However, these spikes in approval ratings are usually short-lived and eventually decline over time.
