Multiple-Choice Questions (4 marks)
Question 32&33 : Quoll & Fieldwork. These questions will test how fieldwork is used to study animal behavior in its natural habitat and how observational data reveals seasonal activity patterns.
Question 39&40: Ethical Approaches. You'll need to apply consequences-based ethics to a scenario, showing you understand how this approach focuses on maximizing positive outcomes while minimizing negative ones.

Short-Answer Questions (14 marks)
Question 9: Human Evolution & Fossils. This question is about the limitations of the fossil record. You should explain how a lack of complete fossils, the fragmentary nature of samples, and the physical similarities between species make it difficult to determine evolutionary relationships.
Question 10a: Explain how the presence of Denisovan DNA in modern humans provides evidence of interbreeding, even without fossil records in some areas.
Question 10b & 10c: Use the Denisovan D1, D0, and D2 populations to show how genomic differences can reveal past selection pressures and evolutionary divergence.
Question 10d: Consider how new fossil discoveries or the possibility of interbreeding within Australia could change our current understanding of Aboriginal migration history.
