Why had the speaker lost their memory about the events of that night in Cleveland ?
Pick the best answer from the following options:
- They had suffered a head injury and as a result had developed retrograde amnesia about the events
 - None of the above choices .
 - They had lost their glasses , and because they could n't make out any details , they had a hard time remembering specifics
 - The alcohol had suppressed their ability to form memories about the events of that evening
