안녕하세요~

덕분에 Inro to AI강의 너무 잘 들었습니다. 꼼꼼한 설명 감사드립니다.
다름이 아니라 CAIA 협회에서 배부한 sample exam 풀이 도중 헷갈리는 부분이 있어서 질문드립니다.

문제는 다음과 같은데요,

A fund is organized to deliver beta as cheaply as possible through a passive product tied to a broad financial market benchmark. How would this fund’s strategy be described?

 A  As an asset gatherer

 B  As a process driver

 C  As a product innovator

답은 A라고 되어있는데요, 해설을 보면

Asset gatherers are managers striving to deliver beta as cheaply and efficiently as possible, and include the large-scale index trackers that produce passive products tied to well recognized financial market benchmarks. These managers build value through scale and processing efficiency.

 이렇게 되어있습니다. 그런데  슈웨이저 교재 284쪽에 보면 'Process drivers are asset gatherers in that they are index trackers that pursue passive investments linked to popular benchmark 라고 되어있네요. process drivers가 beta drivers인 것은 암기하고 있었는데, process drivers와 asset drivers의 차이가 무엇인가요?!

감사합니다~!
