閱讀下面的短文，選擇正確答案。

We see with our eyes and taste with our tongues．Ears are for hearing，skin is for feeling and noses are for smelling．Would anyone say that ears can smell，or that tongues can see？Actually，yes．Paul Bachy-Rita，a scientist at the University of Wisconsin，believes that the senses can be changeable．For example，a tongue can be used for seeing．The brain，as we know，is a complex organ．Even when part of it is hurt，it will try to carry out the same function by sending the function to another area of the brain．

A college student was asked to take part in an experiment．In the experiment，his eyes were covered with a small video camera．The camera was connected to a long plastic line which went into his mouth．A computer would change the video' picture into signal．The picture would travel through the plastic line as an electric current，reaching the electrodes （電極板） inside the student's mouth．The scientist would roll a ball towards his right side，left side，or centre，and the student would have to catch it．When the scientist rolled the ball，pain passed over the student's tongue．From the position of the pain on the tongue，the student reached out his hand and caught the ball．

If the brain can see a ball through a camera and a wet tongue，blindness and deafness can be overcome.

參考譯文

我們用眼睛看，用舌頭嘗。耳朵是用來(lái)聽(tīng)的，皮膚是用來(lái)感覺(jué)的，鼻子是用來(lái)聞的。有人會(huì)說(shuō)耳朵能聞、舌頭能看嗎？事實(shí)上，真有人這么說(shuō)。威斯康星大學(xué)的科學(xué)家保羅·貝奇-利塔認(rèn)為，感官是可以改變的。比如，舌頭就可以用來(lái)看。正如我們所知，大腦是一個(gè)復(fù)雜的器官。即使它的部分區(qū)域受損，它也會(huì)盡力把這一功能轉(zhuǎn)移到其他區(qū)域以繼續(xù)執(zhí)行。

一名大學(xué)生應(yīng)邀參加了一項(xiàng)實(shí)驗(yàn)。在該實(shí)驗(yàn)中，他的眼睛被罩上了小型攝像機(jī)。這臺(tái)攝像機(jī)通過(guò)一條長(zhǎng)塑料導(dǎo)線通進(jìn)嘴里。一臺(tái)電腦將把攝像機(jī)拍到的圖像轉(zhuǎn)換為信號(hào)。這樣，圖像就可以像電流一樣通過(guò)塑料導(dǎo)線傳輸?shù)椒旁趯W(xué)生嘴里的電極板上。科學(xué)家把一只球分別向?qū)W生的右邊、左邊或中間滾去，而學(xué)生必須抓住它。當(dāng)科學(xué)家把球滾出時(shí)，痛感傳輸?shù)綄W(xué)生的舌頭上。根據(jù)痛感的位置，學(xué)生伸手抓住了球。

如果大腦能通過(guò)攝像機(jī)和濕漉漉的舌頭看到球，失明和失聰?shù)膯?wèn)題就可以解決了。
