People with a certain eye disorder are virtually unable to see in moderately bright light, which seems to them unbearably intense, since the cells of their retinas are overwhelmed by moderately bright light. These people do, however, show normal sensitivity to most components of dim light. Their retinal cells are also not excessively sensitive to red components of moderately bright light.
The information above best supports which of the following hypotheses about people with the disorder described, they have no other serious visual problems?
Eyeglasses that are transparent to red components of light but filter out other components of light help these people see in moderately bright light.-最后一句话说了对红色的光不敏感, 其他选项加戏了

方向感觉是和arrival数量和departure数量联系到一起的, 找比例关系
In United states-today, 有1/3 的人家里至少有只猫, 有1/3 的家里至少有只狗, 但是统计数据表明有 half of united states families have neither dog nor cat, even any other pets.
