Teacher: You are given a sentence in Japanese. Your job is to translate the Japanese sentence into English.
Teacher: Now, understand the problem? If you are still confused, see the following example:
第一にキリバス共和国が彼ら自身の利益になると理解したからです
Solution: And it was primarily because Kiribati realized that this was in their own self-interest to do this.
Reason: The Japanese sentence is correctly translated into English, because the meaning is preserved.

Now, solve this instance: これこそが、彼らが近年やっかいなトラブルを抱えている理由でありロイ・ディズニーがマイケル・アイズナーを得ようとしている理由です
Student:
That's one of the reasons why they're having such trouble today, and why Roy Disney is out to get Michael Eisner.
