P1: Issue of OCD is introduced
P2: Biological reason of OCD is proposed
P3: Supporting evidence is provided. Opposing evidence is also provided1. Which of the following best describes the organization of the passage?
A. A medical disorder is described, and then two competing theories about the cause of the disorder are compared.
B. A controversial theory is presented, and then supporting evidence is presented to prove that the theory is correct.
C. A mysterious situation is described, a plausible theory is put forth to explain the situation, and the theory is then rejected as incomplete.
D. A psychological disorder is introduced, and then further information about the disorder is presented.
E. An issue is introduced, a theory about this issue is presented, and then evidence for and against the theory is discussed.(True)-as per above summary2. If Swedo’s theory is correct, it can be inferred that which of the following would have the greatest chance of protecting a person from developing OCD?
A. Regular use of a medicine that prevents infection by streptococcal bacteria.-streptococcal bacteria is main culprit here .
f OCD that has been observed in children is due to an overzealous autoimmune response to beta-hemolytic streptococcal bacteria, the bacteria that causes strep throat. In Swedo’s theory, after fighting off an infection of streptococcal bacteria an individual’s immune system may mistakenly attack the basal ganglia, a cluster of neurons in the brain that play an important role in coordinating thought and emotion. This attack then results in the tides of irrational thoughts that afflict OCD sufferers.B. An injection that coats the basal ganglia with a barrier that makes it immune to infection by streptococcal bacteria.
- its the immune system attacks om basal ganglia
C. A throat lozenge that effectively alleviates the symptoms of strep throat.
-
symptoms of strep throat is not the cause.
D. Regular sessions of cognitive therapy that help a patient understand the underlying factors behind their anxieties.
- This is not the root cause
E. Latex gloves that prevent a person’s hands from picking up germs, thereby eliminating the need for constant hand washing.
- Germs? This is not the root cause
3. According to the information presented in the passage, all of the following could be examples of symptoms of OCD, EXCEPT.
A. Avoiding stepping on cracks.(given)
B. Repeatedly turning on and off a light whenever entering a room.(given)
C. Constant hand washing. (given)
D. An inability to relate to other people as human beings. (False)E. Recurring irrational fears about harm befalling loved ones.
(given)
Other sufferers become convinced that unless they follow certain rituals—e.g. turning a light on and off exactly six times when entering a room, not stepping on cracks, avoiding objects of certain colors —harm will befall them or their loved ones. 4. Which of the following statements would provide the most fitting conclusion to the third paragraph?
A. In summary, the case for the connection between OCD and strep throat infections is unproven and, ultimately, not useful for the treatment of this mysterious disorder.
(we cannot say not useful as there are improvements obseved in children suffering from OCD given course of antibiotics)
B. Furthermore, it has been hypothesized that autoimmune responses to bacterial infections could be tied to other neurological disorders such as Huntington’s disease.
(other neurological disorders such as Huntington’s disease is out of scope)
C. Perhaps the most accurate statement that can be made at this time is that the streptococcal connection to OCD is an intriguing theory that might lead to effective therapies for some OCD sufferers.(True)-since children suffereing from OCD have shown improvement on the courses of antibiotics, so might lead to efective therapies)
D. These critics, however, cannot deny that Dr. Swedo’s theory allows doctors finally to provide a cure for this prevalent and disabling disorder.
(Deny is not given in the passage)
E. In conclusion, we will probably never know whether streptococcal infections are the cause of OCD or just an unrelated ailment that sometimes coincides with the onset of compulsive behavior.("never know" is extreme: nowhere mentioned by author)
