Q1. Select all the desirable actions to take with regard to trading with suppliers. 
 Gather information on a daily basis on examples of social issues, etc. in the industries you are involved with. 
 If we undertook strict screening when we began trading, we do not need to create an opportunity to discuss social and environmental matters in the trades that we have commenced. 
 Even if we have been trading with a supplier for many years, we should visit the supplier regularly, check the social and environmental measures taken by the supplier, and request a corrective measure if a problem is found. 
 Even if a supplier seems to have a labor problem, we will not be involved in the problem because we procure materials from the supplier via a local agent.
