Well, I'm saying I disagree with your assertion that it's likely. I'm not saying that just to be contrary, and I got your point to begin with, but I'm glad you outlined it in more detail because it explains why you think it's that thing.The reason I disagree is because, after all, the reason he had to help them wasn't part of the test. If Zeref here was part of the actual challenge (like if Fairy Tail had a pet monster-guardian that was too strong for any team), then I'd agree with your logic, but he appears to be just an outside X-factor.
Not helping others if something else comes along may be an automatic failure, but I don't think helping teammates is an automatic pass, the intended purpose of this part of the test is unknown because there's no part of the test itself that has required mutual assistance. So far it's just a race/search.
Do you now see my point?
I see your point, sort of.
Not helping others from certain death would be an automatic failure.
Helping out others by perceiving this "new" guy as an instant enemy should certainly be S-Class intuition on top of helping your opposing team-mates from certain death.
2 very good reasons that it is a a sure way into S-Class for Natsu.
On top of that, the second test portion just seems like it's there to see if the other teams will cooperate because of how open it is. An S-Class is a leader: if they organized or lead a search party while sacrificing the chance to find the grave but increasing the chance for someone to pass, that also seems like a more likely way to become S-Class. (no one did that, really...)
My way makes more sense in terms of testing a mage to become a leader in the guild and it happens to fall in line with typical themes from manga, in general.
Also, helping out against Zeref should be an automatic promotion to S-Class, especially because he saved the others from death and also immediately recognized him as immensely evil/powerful.
