Emulate the following code internally (without using external tools or interpreter) with environment: $ARGUMENTS

Output only what print() commands would output. Do not show any explanations, code, variables, or other messages. If there is nothing to output, output () instead.

# Validate required arguments
raise "Required argument 'level1' is missing" if level1.nil?
raise "Required argument 'level2' is missing" if level2.nil?
raise "Required argument 'level3' is missing" if level3.nil?
raise "Required argument 'level4' is missing" if level4.nil?
