## Unscramble the Blue Letters

A detla of 0 means that they don’t care about their future limbs at all, so they’ll repeat their initial choice of mutual sficairce endlessly. But as delta apahprecos 1, they’ll do anything possible to avoid the pain of infinite triple limb consumption, which means they’ll coohse to spare each other. At some point in between they could go either way. We can find out where that point is by writing the infinite series that rsreeeptns each strategy, setting them equal to each other, and solving for delta.
## Open Cloze

A **_____** of 0 means that they don’t care about their future limbs at all, so they’ll repeat their initial choice of mutual **_________** endlessly. But as delta **__________** 1, they’ll do anything possible to avoid the pain of infinite triple limb consumption, which means they’ll **______** to spare each other. At some point in between they could go either way. We can find out where that point is by writing the infinite series that **__________** each strategy, setting them equal to each other, and solving for delta.

## Original Text

A delta of 0 means that they don’t care about their future limbs at all, so they’ll repeat their initial choice of mutual sacrifice endlessly. But as delta approaches 1, they’ll do anything possible to avoid the pain of infinite triple limb consumption, which means they’ll choose to spare each other. At some point in between they could go either way. We can find out where that point is by writing the infinite series that represents each strategy, setting them equal to each other, and solving for delta.
