If your BAL is .10, you can expect a __________ drop in complex performance compared to the sober level.36%24%17%13%

To address the question regarding the expected drop in complex performance with a Blood Alcohol Level (BAL) of .10, we need to analyze the provided options.

Breakdown of the Problem

1. Understanding BAL: A BAL of .10 is significantly above the legal limit in many jurisdictions and indicates impairment.
2. Identifying Performance Drop: The task is to match a probable drop in performance with the numerical options provided (36%, 24%, 17%, 13%).

Relevant Concepts

1. Blood Alcohol Concentration Effects: Research has indicated that higher BALs can impair cognitive and motor skills.
2. Performance Drop Studies: Studies show that a BAL of around .08 to .10 can result in a substantial reduction in complex performance metrics.

Analysis and Detail

1. Research Findings: Generally, a BAL of .10 might result in a performance decline ranging typically from 20% to 30% or more depending on the complexity of the task.
2. Assessment of Options:
   • 36% is quite high and may be more reflective of a higher BAL.
   • 24% is also higher but aligns with some research findings.
   • 17% falls within a plausible range for moderate impairment.
   • 13% is less likely for a BAL of .10.

Verify and Summarize

1. After considering the implications of a BAL of .10 and the potential drops in performance, the most reasonable options to consider are 24% and 36%.
2. However, due to the threshold of impairment a BAL of .10 represents, a 24% drop seems more realistic based on various studies.

Final Answer

Given the data and analysis, with a BAL of .10, you can expect a 24% drop in complex performance compared to the sober level.
