Your question is Characterizing a Sample With Sparse Data. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Tell me about a time you had to characterize a new material sample or technical problem with very limited initial data. How did you decide what to do first, communicate uncertainty, and drive the work to a useful conclusion?
