GRAYLOG - Chapter 3, Exercise 1 Solution
==========================================================
Naming Level 4 and Comparing Its Severity

PROBLEM
-------
Using this chapter's own real severity table, name the syslog severity
name for level 4, and state whether it's more or less severe than
level 6.

SOLUTION
--------
Looking up level 4 in the chapter's own real severity table:

    4 = Warning

Comparing severity: this chapter established that LOWER numbers mean
MORE severe. Level 4 (Warning) has a lower number than level 6
(Informational), so level 4 is MORE severe than level 6.

ANSWER: Level 4 is "Warning." It is more severe than level 6
(Informational), because lower syslog severity numbers indicate greater
severity.

----
WHY THIS WORKS AS AN ANSWER

This is a direct lookup against the chapter's own real severity table,
combined with its own explicitly stated ordering rule. The comparison
is a good check on whether the "lower = more severe" rule has actually
been internalized, since it inverts the intuition most people bring
from an everyday 1-10 rating scale, where a higher number usually means
worse.
