I think the kids would take "Mr. Ziggy is now/has been chosen to become a Power Ranger" far better than Mr. Ziggy is going to. Of course, nobody would go into things like Ziggy's willingness to be a Ranger. The kids think it's great, except one or two who think he looks "sad".

The adults? Well, he'd have to explain to his boss that he passed the tests and he'll be taught how to fight, and she'll want to know if he's okay and whether he's been conscripted, and how she can get him out of it.

(I think I managed to do my homework coherently. I think.)
