Context: I did n't have to play any more CDs , but I went back to the MP3 player later and managed to mute the cable - change noise . So at least there was a learning curve . The microphone was difficult . I expect there are better ways to hold and speak into it , as I struggled to make myself understood .
Question: Which of the following was not a part of the learning curve ?
Option 0: Making myself understood while speaking .
Option 1: Holding the microphone correctly .
Option 2: No longer having to play any more CDs .
Option 3: None of the above choices .
Answer: 2
