Answer 2

The correct answer is "you don't need a precise definition". It is common to find unfamiliar words in texts, especially when a specialized article is being read. In these cases it is possible to use context to figure out the meaning of the unfamiliar words if a precise definition is not needed. This helps to understand the general idea of the text without checking the meaning of the words in a dictionary.
