Given an abstract, indicate which of the provided candidate titles (Option1 and Option2) best describes it (respond with the text of the title, not option1/2).

[EX Q]: Abstract: This article describes the circumstances of the diagnosis of three of a group of 12 high-functioning multiple personality disorder patients. All had performed major social and professional activities with consistent competence, and all appeared to be neurotic patients suitable for classical psychoanalysis. All 12 had been misdiagnosed on at least three occasions before the correct diagnosis was made. Aspects of the difficulties encountered in assessing these patients are discussed and guidelines for the preservation of their high level of function during the treatment process are offered.
Which is the apt title for the abstract? option1: High-functioning multiple personality patients. Three cases. option2: Reactive gliosis simulating butterfly glioma: a neuroradiological case study.

[EX Q]: Abstract: The renal effects of carbohydrates (CHO) were studied in two experiments. 1) The effects of CHO-energy restriction was evaluated by comparing uremic growing rats (initial weight: 80 g) fed "ad lib" (L rats) or CHO-restricted (starch and glucose) but receiving identical amounts of all other nutrients (R rats). R rats showed reduced growth, slower increase in plasma creatinine, lower mortality rate, and less histological renal damage than L rats. 2) Two types of CHO restriction, low glucose (R1 rats) or low starch (R2 rats) were compared to "ad lib" feeding (L1 rats) in adult rats (initial weight: 130 g). Growth was identically reduced in R1 and R2 rats. Mean plasma creatinine levels at week four was lower in R1 than in L1 rats. The overall rate mortality was higher for L1 and R2 than in R1 rats (79%, 81%, 53%) but included deaths from other causes than renal failure. Actuarial survival excluding these deaths was 27%, 83% and 10% in L1, R1 and R2 rats, respectively. Diffuse renal lesions were found in 25 of 30 L1, 5 of 15 R1, and 12 of 15 R2 rats (R1 vs. R1 and R2, P less than 0.01). The results show that CHO restriction may preserve the renal parenchyma, and suggest that restriction of "simple" rather than "complex" CHO restriction may be beneficial, a finding which could be of clinical importance if confirmed by further investigations.
Which is the apt title for the abstract? option1: Role of amount and nature of carbohydrates in the course of experimental renal failure. option2: Vaginal discharge. Its causes and cures.

[EX Q]: Abstract: The study reported here provides information on National Board of Medical Examiners (NBME) examination policies from all U.S. medical schools (n = 67) that require students to pass the examination. Most of these schools have similar policies on use of a 380 total score as the passing level for the NBME Part I examination, allowing three attempts to pass the examination, interrupting a student's progress into the clinical curriculum upon failure of the examination, officially providing time for preparation for taking the test, and requiring students to pass the Part II examination.
Which is the apt title for the abstract? option1: Policies of U.S. medical schools on the use of the NBME Part I and Part II examinations. option2: The origin of prenatal and postnatal deformities.
