It was spelled out in the review. See @Christy’s thread over here:
Before you get angry and disgusted, the first view isn’t YEC. All four views accept the facts of evolution. The first option is that God selected two historical individuals (Adam & Eve) from an existing population and placed them in a Garden, where God interacted with them and taught them. The second option is similar, but instead of sinfulness being spread immediately as alienation from God, the knowledge of good and evil spread gradually throughout the population. As I understand your previously expressed opinions about A&E, don’t you fit underneath one of those umbrellas, regardless of the exact timing?
