我也找不出錯誤是哪個....請教文法高手

另外training in signals and satellite relays.該如何翻譯咧?我分不清這裡的training 是, and train的縮寫 還是which train的縮寫.......??????

我手邊的題目跟你不太一樣喔！我的是：
Telecommunication systems involve the transmission of sound, pictures, words, and other types of information by electronic means, include radio signals and satellite relays.

答案是(C) include -> including
