Can I please get some help answering?

Question is based on case information

Case information: Cyber Systems Pty Ltd is a provider of web and mobile based search and booking platforms. Travel agencies throughout Australia engage Cyber Systems to design and maintain their travel search and booking platforms. As a company specialising in the design and setup of search and booking platforms, Cyber Systems is able to provide clients with better quality platforms, more efficiently than they could otherwise do through employing their own staff. The COVID-19 pandemic has hit travel agencies particularly hard, with international travel largely coming to a halt and a substantial decline in domestic travel. For Cyber Systems, this has meant that clients have cut back requesting new platform designs and reduced system maintenance requests as much as possible. Many clients are experiencing great financial difficulty and have delayed paying amounts owed to Cyber Systems. In the context of this case, please answer questions 9 - 12 that follow:Cyber Systems' management has been actively pursuing clients who fail to pay invoices when they fall due. Based on the experience of Cyber Systems in the 2021 financial year which ends on June 30, the longer an account receivable is outstanding, the more likely the client never pays the amount due. The longer the account is due, the more likely the client closes their travel agency and can never pay amounts due to Cyber Systems.
