Hmmm... There seems to be a consensus building agains me on this one. I was going for something more like ignoring the counterevidence or one-sided assessment. T-bills do have risk, but risk can only be assessed relative to other options. (T-bills have beta < 1)
But I fear I may be reading too much into this one. Given the vagueness of the example, argument from ignorance and false premise seem equally valid.
So we'll call this point for Rabbit.
