It seems that in 1826, bananas were taken from South China to England.W: I suppose they would have made a welcome addition to the English diet.M: Yes, I’m sure. Well, apparently there was an English Duke who was particularly fond of bananas and he used to cultivate them in his hothouse, which is where you have to grow them in England, of course, because of the cool climate and they became quite popular in the UK.对话中菲奥纳听到马丁研究香蕉的种植史时提出了疑问，马丁马上表示这个话题并没有她想象中那么无聊，表述错误。故为B。
