Why can't "How are they" be a valid answer? "How are they" is identical to "what are they like" in english...
This questions is about permanent traits. They may be strong, good (people) or wicked. How are they? asks about them now. They may be good (fine), well (healthy), sad or sick.
I believe it should be accepted as well, it isn't just used for the current state but also for permanent traits depending on the context. Eg, If you move to a new school, your friends may inquire about your new classmates by using "How are they?" meaning the same thing as "What're they like?"
Indeed, "How are they" is frequently used to inquire about enduring qualities, at least in American English. E.g. "You have new shoes! How are they?" or "You've used this delivery service. How are they?"
Jakého druhu jsou.
Jaký druh jsou.
Jaký je to druh.
and probably more options but they would most likely all contain DRUH = KIND
Because it's palatalization (is it correct word in english??).,in nominative/vocative plural in front of -í there are changes: r--ř, k--c, h--z, ch--š,d--d´, t--t´, n--nˇ.,
