A.people admitted that the brick would fall.

B.people' s gaze force could keep it from falling.

C.people' s gaze could support the added weight.

D.people believed that the gaze force was strong.

参考答案：A

参考解析：

从原文第4段可以得知：But this force was not strong. When the researchers replaced the cardboard tube with a brick the subjects felt that the Jedi eye-beams wouldn't support the added weight. They said the brick would fall at the same angle, whether or not there was someone there to watch it.说明人们的注视作用不大，物体本身是要跌倒的。选项A：人们承认砖头会掉下来；选项B：人们的注视力可以阻止它下降；选项C：人们的目光可以支撑增加的重量；选项D：人们相信凝视的力量是强大的。只有A选项符合文章内容，其余三项与原文表述相反。故本题正确答案选A。
