Hi DeadScout,You're right that adding C doesn't force one single interpretation. But that's fine, and here's the key idea:
a strengthener never has to prove the conclusion or shut every other door. It only has to tip the scale by knocking out one competing explanation. So "I could still read it differently" doesn't disqualify C.
Let's pin down the exact rival explanation C is killing. Look back at the original result: elephants spent more time near their
own herd's distressed calf. A skeptic could say,
"That's not care - they just linger wherever they recognize a familiar face." If that were the real driver, then seeing their own calf
freely visible outside the enclosure should hold their attention just as much.
Now read C carefully:
"...spent more time at the enclosures when a distressed calf from the elephants' herd was in the enclosure than when a distressed calf from the elephants' herd was visible but outside the enclosure."Same calf, same herd - the only change is whether it's trapped-and-in-need versus free-and-fine. The elephants gave
more time to the one that actually needed help. That ties their behavior to the calf's
need, which is exactly what "care" means - and it weakens the "just recognizing a familiar face" story. That's the strengthening move bb was pointing to in the thread.
A simpler stand-in: Claim -
"Sara studies hard because she wants top grades." Evidence - she studies more before big exams than small ones. Strengthener -
she studies even when no one is watching. That doesn't
prove her motive, and you could still imagine other reasons - but it removes the rival "she's just doing it for show" explanation. Same job C is doing here.
So C wins not by ending all debate, but by being the only choice that removes a live alternative to "care."

I still may interpret the results differently even when C is added as a premise
