I don't know if it's common in other languages, but usually we know who we are talking about. So no need to seperate he/she.
If you didn't know and you were talking about people you don't know who they are and what their names are, how to you convey the fact that the person is a he or a she? In my mother tongue, Arabic, we have "he" and "she" as does English.
It doesn't say she was the most experienced. It says that couple days earlier she was leading a dive and the day before she was leading some norwegian divers, because she was the most experienced of that group.
Doesn't this mean that she was the most experienced in her group?? I wasn't talking about "most experienced" in the world above, I was talking about being the most experienced in her group naturally.
The facts presented so far don't add up to justify why she panicked or why she expired. Nothing seemed exceptionally difficult, there was no air loss or anything that causes extreme panic to the point of mysteriously dying. Typical cave diving courses have the students go through lots of scenarios simulating equipment issues before the diver is caver certified. It doesn't add up so far based on the facts presented.In one moment she was leading the dive. Shortly after she was using her hands to back her off. And at that time she had already lost the control of herself. She had panicked for a reason unknown. I don't what there is to add up.
