Hi, everyone.
Everytime I read a sentence like below, I get confused because I don't know how to divide the nouns.
Finally, academic scientists and leaders in biotech, medical imaging and big drug companies recognize "there is more to AD than B-amyloid alone," the paper concludes.
Question: Who recognize "there is more to AD"? Are they;
1. academic scientists, leaders in biotech, medical imaging and big drug companies, or
2. academic scientits, leaders in (biotech, medical imaging and big drug companies)?
Which words does "leaders" modify?
Thank you,
Higurashi
