Answer 1

I'm not really sure what to comment here, it seems self-explanatory. If not, leave a comment and I'll clarify.

$ExampleHashTable = @{
    "one" = "the loneliest number"
    "two" = "just as bad as one"
}

Function PassingAHashtableToAFunctionTest {
    param(
        [hashtable] $PassedHashTable,
        [string] $AHashTableElement
    )

    Write-Host "One is ... " 
    Write-Host $PassedHashTable["one"]
    Write-Host "Two is ... " 
    Write-Host $AHashTableElement
}

PassingAHashtableToAFunctionTest -PassedHashTable $ExampleHashTable `
    -AHashTableElement $ExampleHashTable["two"]

Output:

One is ... 
the loneliest number
Two is ... 
just as bad as one
