Answer:
White Fang is beginning to develop better instincts about the humans
Explanation:
The excerpt shows that White Fang was beginning to develop better instincts about humans. Instinct, is an acquired or natural tendency to evaluate a situation and know the right response to it.
In the case of White Fang above, his instinct about humans was better developed as he was able to deduce that the noise made by the man was not hostile, thereby making him come closer to him.
What it means is that he wouldn't have been able to get where he got if it hadn't been for the scientific achievements of his predecessors. If it hadn't been for these "giants" that enabled him to see so far, he wouldn't have been able to make all the discoveries that he did. For those coming after him, he was a giant that enabled them, and so laws and theories and scientific knowledge always increases based on the knowledge before it.
I believe its the ability for the word to be pronounced. This is not something that can be done in a paperback and allows the reader to know how to pronounce the word correctly.
