Q: How do you extract first member of the tuple?

A: Use function Tuple.Item(0)

MDX Query example:

SELECT {([Date].[Calendar].[Calendar Year].&[2003]
, [Customer].[Customer Geography].[Country].&[Canada]).Item(0)
}
ON 0
FROM [Adventure Works]

Different query:

SELECT {([Date].[Calendar].[Calendar Year].&[2003]
, [Customer].[Customer Geography].[Country].&[Canada]).Item(1)
}
ON 0
FROM [Adventure Works]

Result is different:
