On which of the following aspects does Frisen disagree with some radicals？
A．Whether research should be done on embryonic stem cells.
B．Whether research should be done on adult stem cells.
C．When should people expect a drug for Parkinson"s.
D．When should clinical trials of stem-cells research begin.
参考答案
正确答案：A
解析：细节题。根据题干中的radical及题目顺序定位至末段。首句指出一些右翼激进分子的观点：scientists ought to concentrate solely on adult stem cells。在第二句提到“He happens to disagree”之后，指出Frisen的观点：To really understand adult cells，we need to master how embryonic stem cells work．可见Frisen认为两种细胞的研究都重要，即他们的分歧在embryonic stem cells，故[A]为答案。
