The Utility of Ordinary Cardinals

MICRO-OYG5N4

Cardinal Richelieu, a fictional character of "Three Musketeers" fame, gets a utility of 100 when Athos, Porthos, and Aramis are killed off. Armand Jean du Plessis, a real life Cardinal of Richelieu (and of Fronsac), gets a utility of 50 when the Three Musketeers - Athos, Porthos, and Aramis, if you have not read the book - are killed off.

What can we say when we compare Cardinal Richelieu and Armand's utility when Athos, Porthos, and Aramis are killed off? It is safe to assume that utility is ordinal.

A

The fictional Cardinal Richelieu likes the killing off of the Three Musketeers twice as much as real-life Armand.

B

The fictional Cardinal Richelieu likes the killing off of the Three Musketeers more than real-life Armand, but we can't really say by how much.

C

Real-life Armand likes the killing off of the Three Musketeers more than the fictional Cardinal Richelieu, but we can't really say by how much.

D

We cannot make a direct comparison of utilities across the two individuals.
