What does it mean if a phenomenon is said to be puzzling?

1. It is easily understood.

2. It is well-documented.

3. Its cause or explanation is in question.

4. It is commonly accepted.

The correct answer is: Its cause or explanation is in question.

A phenomenon described as puzzling implies that its cause or explanation is uncertain or unclear. This term suggests that there are aspects of the phenomenon that challenge our understanding, leading to confusion or the need for further investigation. When something is puzzling, it typically indicates that existing knowledge does not adequately account for it, creating a need for deeper exploration or research to clarify the underlying mechanisms or reasons behind the phenomenon. In contrast, the other options indicate clarity or acceptance: something that is easily understood is straightforward; well-documented phenomena are backed by abundant evidence; and commonly accepted phenomena are those widely recognized and agreed upon without significant debate or confusion. Thus, the term "puzzling" specifically highlights a lack of resolution or clarity concerning the phenomenon in question.
