To organize numbers from greatest to least you:
1. Seoparate the possitive numbers from the negative numbers:
Possitive numbers are bigger than negatives,
You have some absolute values, the absolute values always will be possitive numbers as they are distances, then:
[tex]\mleft|a\mright|=\mleft|-a\mright|=a[/tex]
Example:
[tex]\mleft|-6\mright|=6[/tex]
Then so, the correct answer of numbers ordered from greatest to least is:
[tex]8,\mleft|-6\mright|,5,\mleft|-4\mright|,\mleft|1\mright|[/tex]
