The Natural Approach and the Input Hypothesis emphasize unconscious acquisition by receiving comprehensible input. The Natural Approach is the method focusing on providing understandable spoken language known as comprehensible input and classroom atmosphere without anxiety. Learners listen to the teacher’s use of the target language and try to understand it while remaining silent. If this comprehensible input is provided adequately‚ language acquisition progresses “naturally” (Larsen-Freeman)

The models on the disbursement of modern humans include the Out of Africa hypothesis and the Multiregional Continuity hypothesis. The Out of Africa hypothesis explains that modern humans first evolved in Africa and then migrated out to Asia and Europe‚ displacing the archaic Homo sapiens already habituated there. In contrast‚ the Multiregional Continuity hypothesis explains that evolution of modern humans occurred regionally and without replacement‚ meaning that each continent’s archaic H. sapiens

The criteria for a hypothesis-based scientific study involves a few steps that should be followed in order. First‚ an observation is made and then a question should be posed about the observation that can be tested and possibly proved false. Next‚ we can make a hypothesis or educated guess about the result cause of the problem. We can then make a prediction on what may fix the issue. The final step would be to test our prediction to find the conclusion. The difference between a scientific based
