In a noisy workplace in which you are the manager, you decide that the best approach to dealing with the complaints of noise by your workers is to provide the latest-design earplugs. You do not consider other options. This is not the best approach because ... (which of the below best summarises the arguments?) 

 

1- earplugs wear out and get dirty and will need to be replaced continuously

 2- the remedy does not address the issue of noise systemically and instead relies on individuals taking action

3-  it would be easier to hire new workers who don't complain so much 

4- some workers might not want to wear ear plugs anyway, so earplugs are ineffective
