#### Answer

1) Decrease 2) Increase

#### Work Step by Step

Recall, rotational inertia is inversely related to the distance the mass is away the axis of rotation. Thus, in case 1), since the mass is closer, rotational inertia decreases, while in case 2), since the mass is further away, rotational inertia increases.
