{'standard audible capacity': [1, 0, 0, 0], 'decibels': [1, 1, 0, 1], 'healthy human being': [1, 0, 0, 0], 'range': [5, 0, 6, 7], 'world health organisation': [2, 1, 0, 1]}
The World Health Organization (WHO) has determined that the standard audible capacity of a healthy human being falls within the range of 5-10 decibels. Decibels is the unit used to measure sound intensity. Option 1, 45-50 decibels, and option 2, 200-250 decibels, are both considerably higher than the standard audible capacity and would likely indicate hearing impairment or the presence of very loud sounds, such as a jet engine or an explosion. Option 4, 2000-2500 decibels, is an extremely high and unrealistic range that does not align with normal human hearing. Therefore, the correct answer is option 3, 5-10 decibels, which is supported by the World Health Organization`s guidelines.
