Example output: Italy have defeated Portugal 31-5 in Pool C of the 2007 Rugby World Cup at Parc des Princes, Paris, France.

Also, translated sentence preserves the numbers as it is and converted sentence is sentence case.
Q: AAIBは、さらに他の航空機の設計が危険かどうか不明であることを指摘し、防氷作用のある添加物の使用を増加させる調査をし、航空機燃料システム内での氷の蓄積と突然の動き、燃料そのものの中での氷の実際の形成についての両方を調べるようにFAAとEASAに助言した。
A:
The AAIB further noted that it is unclear whether other aircraft designs are at risk, and advised the FAA and EASA to look into increased use of de-icing additives and investigate both the accumulation and sudden movement of ice in aircraft fuel systems and the actual formation of ice in the fuel itself.
