A tribe or race became extinct in the development of history, but its text will be passed down. "Arilo" is such a text. Archaeologists found this text inland. After researching "Arilo", there is no text for "sea", but there are texts for "winter", "snow", and "wolf". Therefore, experts speculate that the tribes or races that use the word "Arilo" have historically lived in a cold place away from the ocean. Which of the following, if true, would most weaken the speculation of the above experts? ['There is no word for "cloud" in "Arilo".', 'There is no word for "mountain" in "Arilo".', '"Arilo" has the word "hot".', '"Arilo" has the word "fish".']
