试题解析
A[试题分析] 推理题。[详细解答] 第二段中提到：To test the possibility that the cards reflected heat differently，he heated some and cooled others without affecting her response to them．He also found that she could read newsprint under glass，so texture was giving her no clues．根据文中所说Rosa Kuleshova的特异功能，是不看不摸，能感知事物，这里，用玻璃，显然是防止触摸，以增加实验的严格性。故答案为A。
