What kind of tasks are less affected by tolerance when levels exceed 0.08?

The correct choice is that complex or naive tasks are less affected by tolerance when alcohol levels exceed 0.08. This is significant because as a person's blood alcohol concentration (BAC) rises, their ability to perform complex tasks—which often require higher cognitive function and coordination—tends to deteriorate more noticeably. However, individuals with a higher tolerance may maintain some level of performance on these tasks compared to simpler tasks, which can be more impacted or show diminished capacity even at lower BAC levels.

Simple motor tasks, such as basic coordination movements, are generally performed with less cognitive load and thus can be more noticeably affected by alcohol impairment, especially as levels rise. Walking and talking may also be considered simpler actions that tend to show impairment, but they are still more mechanistic routines compared to the planning and execution required for more complex cognitive tasks. As the BAC increases, it becomes increasingly difficult for individuals to effectively manage complex tasks, making the performance decline more pronounced despite tolerance.
