Answer:Maybe Karen instruction about time concerning the meeting was not clear to Richard and her emotions interfered with their conversation
Step-by-step explanation:Richard came to meet Karen late and unprepared. He was committed to look over the history test but the heat at the moment created unconducive environment for the two to revise. Karen should have noticed that Richard was unprepared thus approach the conversation by choosing words carefully while keeping in mind the state of his receiver and the words to use. Karen could have ignored the challenges and get specific by going straight to the point which was history revision.
