Q2 Daniel and his friends went from Royalty to being a student in a foreign country. The leader was going to make them members of his court after their education lasting 3 years. At that time they wouldn't remember where they had come from, but only their new home. They would become Babylonians from their new name to their speech to their thinking. On the question regarding being made eunuchs, I can't quite make up my mind. Upon further investigation in outside resources on the definition, I am just not sure. I found three definitions of the word. Strong's #5631 mentions "valet" or "minister of state" and #7249 mentions "chief chamberlain". I will say that yes they were probably eunuch's but with their bodily parts in tact. Otherwise they would not have been "perfect" or "without any physical impediment". But on the other hand, they may have been eunuchs so there would be no reproduction, which would have an effect on the population of Israel. I am sure there were compromises, especially when first taken to Babylon. My first guess as to why would be to stay alive.
