Children with photosensitive epilepsy, a condition in which seizures

Children with photosensitive epilepsy, a condition in which seizures are triggered by visual stimuli that form patterns in time or space, such as flashing lights or regular moving patterns, are usually not allowed to use computers as the images on the screens are continually refreshed. These images can hence move or flicker, triggering a seizure. However, laboratory tests have shown that the eyes of such children adapt very well to using computers. Parents, therefore, can safely let such children use computers to do extensive research work for school projects, if not for playing games.

Which of the following, if true, weakens the conclusion drawn above?

A. Research typically requires the brain to use less energy to interpret visual stimuli than games do.

B. Parents of children with photosensitive epilepsy are unlikely to be aware of the latest findings made by scientists in the field.

C. Playing games is not as tiring a mental activity as doing research work on computers is.

D. Preliminary results have shown that the brain of such children cannot process constant inflow of images for long hours, and such an inflow could trigger a seizure.

E. Seizures can also be triggered by sources such as smart phones, televisions and game stations, which display moving or flickering images in much the same way as a computer does.
