correct answer is #1,i dont know why
here is the complete paragraph:
Research on OCR sufferers has found certain physiological trends. In particular, many studies show an overactivity of blood circulation in certain areas of the brain. As a result of this increase in blood flow, the serotoninergic system, which regulates emotions, is unable to function effectively. Studies have also shown that OCR sufferers have less serotonin than the average person. This type of abnormality is also observed in Tourette syndrome and Attention Deficit Hyperactive Disorder. People who developed tics as children are found to be more susceptible to OCR as well. Many reports of OCR point to infections that can trigger the disorder, namely streptococcal infections. It is believed that a case of childhood strep throat can elicit a response from the immune system that produces certain neuropsychlatric disorders, such as OCR. |

Only the first is valid, because not only is it grammatically correct but it fits smoothly into the following text.
The other three would make no sense at all.
