A.I. Explanation:

Option 1: "The Bermuda Triangle has always been shrouded in mystery."

Explanation: The text explicitly states that there are no scientific proofs of any mystery surrounding the Bermuda Triangle, contradicting the idea that it is shrouded in mystery. The author emphasizes that many theories exist but do not substantiate a true mystery.

Option 2: "The missing ships in the Bermuda Triangle’s domain perhaps were lost to identifiable reasons."

Explanation: While the text mentions some identifiable reasons like ill luck and navigational incompetence, it does not support the idea that these reasons are definitive or widely accepted. The author presents a range of theories, indicating uncertainty rather than confirming identifiable reasons.

Option 3: "The missing ships and planes around the Bermuda Triangle have aroused public curiosity."

Explanation: This option aligns with the overall theme of the text, which discusses various theories and the public's fascination with the Bermuda Triangle. The mention of 'many theories' and the lack of scientific proof suggests that the topic indeed arouses curiosity, making this the correct answer.

Option 4: "No one has taken up serious investigation on the mystery of the Bermuda Triangle."

Explanation: The text does not state that no serious investigations have been conducted; rather, it discusses various theories and opinions about the Bermuda Triangle. This option misrepresents the author's point by implying a lack of investigation, which is not supported by the text.
