Whenever we are reading drama or poetry it is important to be clear on what the historical context is for a number of reasons such as finding valid explanations or interpretations and placing ourselves in the general trends of the specific period. History shapes the direcction of every piece of literature since it involves society and cutural behaviour, thus by understanding and connecting ourselves to the historical context we can find the answers that may arise from the drama or poetry that is being studied. Moreover, we need some definitions of the environment and the age when the literature takes place since lacking of the understanding of these elements finding a relationship between society and the liteture would be extremely complicated.
In both inference and observation, you have to monitor or observe something.
Here's one example, you can build on it:
Sherlock Holmes 'observed' the scene below him.
His 'inference' was based on the evidences given to him.
Here's the definition of both of them...
the action or process of closely observing or monitoring something or someone is called observation.
a conclusion reached on the basis of evidence and reasoning is inference.
Answer: The last word of Keesh was "It is not for a boy to know about witches, and I know nothing about witches. I only have means whereby I may kill an ice-bear with ease, that's all. It would be headcraft, not witchcraft".
In "The Story of Keesh" by Jack London, the people of the tribe did not believe that Keesh had hunt a large polar bear by himself, so they accused him and his mother of witchcraft. It required dignity and manhood for him to defend himself and speak against the elder hunters who disliked him.
