问题 Despite much educated conjecture, there remains no proven relationship between sunspot cycles and the earth’s weather.
选项 A、argument
B、confusion
C、speculation
D、disagreement
答案 C
解析 A选项argument意为“讨论，论据”；B选项confusion意为“混乱，混淆”；C选项speculation意为“思考，推测”；D选项disagreement意为“分歧，异议”。conjecture在这里是名词，意为“推测，猜测”。如果不认识这个词，可根据本句的直接语境no proven relationship来判断，既然二者的关系没有被证实，那conjecture只能是猜测，因此，C选项正确。本句大意为：尽管有大量基于经验的推测，但仍然没有证据证实太阳黑子周期与地球天气之间的关系。
