### HideShow timer Statistics

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.

Conclusion
Parents can safely let such children use computers to do extensive research work for school projects, if not for playing games
extensive research does not trigger seizure
playing game does.

A- Using less energy has nothing to do with triggering seizures -Out
B-They are not aware , but this info does not weaken the conclusion-Out
C-This might be valid although getting tired and seizures are unrelated -at least here --Out
D-It weakens the conclusion , as research likely involves long hours of Image Inflow. --Should be the answer
E-Gives alternative sources , but it does not weakens the argument.

D it is !!

Pre-Thinking Approach

Let’s see how we can make the conclusion less believable. To do so, we will look at the logical structure, focusing on linkage 1 and the conclusion.Thus the way to weaken the conclusion will be to weaken or break this linkage i.e. find a new piece of information that may suggest that the parents should not let their children with PE use computers to do extensive research work for school projects.

Linkage#1 – Laboratory tests have shown that the eyes of such children adapt very well to using computers.

Weakener 1 – What if the tests contained atypical use of computers by such children, use that has little in common with extensive research work for school projects.
Instance 1: Almost all the laboratory -tests conducted on such children employed reading text-based documents, material that is not representative of the kind of visuals children are likely to encounter while doing online research.
Weakener 2 – What if the eyes are not the only sensitive organs triggering seizures in such children? What if the use of computers affects some other organ more severely than it affects the eyes?
Instance 2: Latest research has shown that the brain of a photosensitive epileptic child is significantly more sensitive to processing continuous visual information than the eyes are and is hence more likely to trigger seizures.
With this understanding in mind, let’s take a look at the option statements.

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

Incorrect – Irrelevant

The relative requirement of energy by the brain to interpret visual stimuli during research and during games is irrelevant to the argument as we do not know if energy expended is relevant in the context of what triggers seizures.

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

Incorrect – Irrelevant

Whether the recommendation made by the author is actually put into practice or not is irrelevant to the validity of the recommendation.

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

Incorrect – Irrelevant

This option has no bearing on the argument as we do not know what effect mental fatigue has on triggering seizures in such children.

c 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.

Correct

D
This option is written along the lines of our pre-thinking linkage weakener 2-. It suggests that even if the eyes of such children adapt very well to using computers, parents should not let them use computers.

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

Incorrect – Irrelevant

This option is about other sources that may trigger seizures; however, as the argument focuses on the use of computer, these other sources are irrelevant to the argument.
