参考答案

正确答案：D
解析：根据文中的"Even the wrong nonverbal cue can bring havoc to a product．A baby food companyinitially packaged their African products just the same as in the U．S．一with a cute baby picture on theiar．They didn’t realize that because so many Africans cannot read，nearly all packaged products soldin African carry pictures of what is inside．"可知，多数非洲人不识字，几乎所有在非洲出售的有外包装的产品，里面销售的都是图片上的产品。再根据“bring havoc to a product”可知，D项为正确答案。
