(单选题)

Which of the following is NOT a potential attendee?

A.Scientists without visas

B.Scientists who are not feeling well

C.Scientists with physical disabilities

D.Scientists who don’t understand childcare

参考答案：D

参考解析：

细节理解题。根据文章第三段第一句“Meeting spaces that are inaccessible to some disabled scientists, health considerations, a lack of access to childcare and travel restrictions can all end up alienating potential attendees from physical conferences”可知，身体残疾、身体不适、无法获得托儿服务、没有签证等原因都会导致潜在的与会者不能参加实体会议。原文提到的“a lack of access to childcare”是指无法获得托儿服务，而D项“Scientists who don’t understand childcare”是指不了解儿童保育的科学家，多以D项不是潜在的与会者。其余三项在文章中提到，即都属于潜在的与会者。故选D。
