想請教一下此題OG11的解釋文
OG11針對挑錯有一段話
The conjunction and is necessary to show that the two effects are equal and separate. (這我可以理解) When they are separated only by a comma, the second effect appears to be part of the first one, which is not true.
請問上面畫線那段是在講哪一種文法規則？ 沒有概念ㄋㄟ...

[dibert8]

they = effects
所以可能在講 A and B 和 A, and B 的差別. (前者對等,後者附加說明)
