Answer: chosen a telephone as the medium of communication
Explanation: A medium of communication is the tool chosen to pass information from one person to another or a group of people. Popular, private media include telephone, short messaging and e-mail. When choosing a medium of communication, it is important to consider the urgency and importance of the information. When important, the person relaying the information has to make sure the recipient receives and understands it. A phone call can ensure this, rather than an E-mail.
