例文（準１級）：Propitious，Conundrum

I received a job offer today, which is quite propitious since I’ve
been looking for a new opportunity for a while. However, the salary
negotiations have become a bit of a conundrum for me.
(私は今日、仕事のオファーを受けました。これは、しばらく新しい機会を探していた私にとっては非常に好都合です。しかし、給与交渉は少し難問となっています。)

Propitious： 好都合の
Conundrum： 難問
