Explanation:

• Question 5: Deforestation is mainly caused by human activities. Slash - and - burn agriculture is a significant contributor. Habitat fragmentation is a result of deforestation rather than the main cause. DDT is mainly related to environmental pollution in other aspects (e.g., affecting wildlife through biomagnification), not deforestation. General agricultural practices are too broad, and slash - and - burn is a more specific and major cause.
• Question 6: Species conservation aims to protect species from extinction. International laws forbidding the hunting of endangered species directly protect species. Petting zoos are more for entertainment and education in a limited sense (not true conservation in the wild - protection sense). Habitat fragmentation is harmful to species. Farmers raising cattle is an agricultural activity, not species conservation.
• Question 7: The Red Panda has the smallest population ($10,000$) among the given species. Generally, a smaller population size makes a species more likely to be endangered.
• Question 8: The Spotted Hyena has a relatively smaller population ($47,000$) compared to the Grey Crowned Crane ($77,000$) and Brush - tail Possum ($4,500,000$), so it is more likely to be or become threatened.
