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.
Despite the narrator’s profusion of animistic (animal-like), humanistic (manlike), and deistic (godlike) characterizations of nature, Crane makes clear that nature is ultimately indifferent to the plight of man, possessing no consciousness that we can understand. As the stranded men progress through the story, the reality of nature’s lack of concern for them becomes increasingly clear. The narrator highlights this development by changing the way he describes the sea. Early in the story, the sea snarls, hisses, and bucks like a bronco; later, it merely “paces to and fro,” no longer an actor in the men’s drama. In reality, the sea does not change at all; only the men’s perception of the sea changes. The unaltered activity of the gulls, clouds, and tides illustrates that nature does not behave any differently in light of the men’s struggle to survive.
The answer is 'glossary'. It is usually found at the end of the book and is a list of the technical terms used throughout the book.

High Temperatures and Plentiful Precipitation
Africa is a continent known for its deserts and
rainforests. As such, because deserts
are characterized by high temperatures, we know “high temperatures” is a proper
response. Too, because rainforests are
characterized by plentiful rainfall in addition to high temperatures, we know
that “plentiful precipitation,” too is correct.
