[Q]: Passage: The placing of the nails in the hands, or the wrists is also uncertain. Some theories suggest that the Greek word cheir (χειρ) for hand includes the wrist and that the Romans were generally trained to place nails through Destot's space (between the capitate and lunate bones) without fracturing any bones. Another theory suggests that the Greek word for hand also includes the forearm and that the nails were placed near the radius and ulna of the forearm. Ropes may have also been used to fasten the hands in addition to the use of nails.
[A]: Do theories say if Destot's bones were fractured?

[Q]: Passage: For many years Arsenal's away colours were white shirts and either black or white shorts. In the 1969–70 season, Arsenal introduced an away kit of yellow shirts with blue shorts. This kit was worn in the 1971 FA Cup Final as Arsenal beat Liverpool to secure the double for the first time in their history. Arsenal reached the FA Cup final again the following year wearing the red and white home strip and were beaten by Leeds United. Arsenal then competed in three consecutive FA Cup finals between 1978 and 1980 wearing their "lucky" yellow and blue strip, which remained the club's away strip until the release of a green and navy away kit in 1982–83. The following season, Arsenal returned to the yellow and blue scheme, albeit with a darker shade of blue than before.
[A]:
What away color socks did Arsenal wear for many years?
