Final answer:
The contributing factors to the outbreak of the Civil War in Syria in 2011 were economic inequality, political repression, and drought and water scarcity.
Step-by-step explanation:
The outbreak of the Civil War in Syria in 2011 was influenced by multiple factors. Economic inequality, political repression under the rule of President Bashar al-Assad, and drought and water scarcity were among the contributing factors. Widespread discontent with the government, coupled with economic challenges and environmental stressors, fueled social unrest and protests, ultimately leading to the eruption of the conflict. Ethnic and religious tensions also played a role, but Syria's ethnic and religious diversity doesn't align with the term "ethnic homogeneity."
