Explanation:

For question 5: Manpages (manual pages) are built-in, immediate references for command-line/development tools, making them the first go-to source to discover a tool's basic functions and usage. Other sources like textbooks, glossaries, external websites, or experts are secondary or more specialized.
For question 6: The visible option "expert" is the standard first source for targeted, direct answers to specific questions when built-in references don't suffice, and since it's the only provided option, it is the intended answer.

Answer:

1. manpages
2. expert
