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: A simple preoperative classification is described to predict the intrauterine and ectopic pregnancy rates following distal tubal microsurgery. Laser CO2 microsurgical salpingostomies were performed on 76 patients between January 1979 and January 1984. All of the patients underwent a preoperative assessment, which included hysterosalpingogram and laparoscopy, to formulate a preoperative classification based on a point system. The patients were divided into four groups according to tubal damage, with a subsequent intrauterine pregnancy rate of 58.3% in grade I, 36.6% in grade II, 9.5% in grade III, and 0% in grade IV. The patients were divided into four groups according to adhesions, with a subsequent intrauterine pregnancy rate of 38.8% with no adhesion, 32.0% with mild adhesions, 26.6% with moderate adhesions, and 5.5% with severe adhesions. From these results, a preoperative management is proposed for patients being considered for either distal tubal microsurgery or in vitro fertilization.
Which is the apt title for the abstract? option1: A preoperative classification to predict the intrauterine and ectopic pregnancy rates after distal tubal microsurgery. option2: Endometrial biopsy in the infertility investigation. The experience at two institutions.

[EX Q]: Abstract: The purpose of this article is to provide information that facilitates the critical evaluation of the thoracic outlet syndrome and other nerve entrapment syndromes in the regions of the posterior cervical triangle and the shoulder. General comments regarding entrapment are followed by discussions of specific entrapment sites. Each discussion stresses the anatomic view and includes comments on causes, symptoms, diagnostic tests, and management.
Which is the apt title for the abstract? option1: Neurovascular entrapment in the regions of the shoulder and posterior triangle of the neck. option2: Elevated plasma vasopressin (AVP) levels during resection of pheochromocytomas.
[EX A]: Neurovascular entrapment in the regions of the shoulder and posterior triangle of the neck.

[EX Q]: Abstract: Pelvimetry can be performed on a computed tomographic (CT) scanner using anteroposterior and lateral scanned projection radiographs (Scout View) plus a single CT slice through the low pelvis. This technique yields accurate measurements of the maternal pelvis that do not need compensation for magnification. The fetal lie and presentation can be easily assessed, along with the fetal neck for hyperextension. In addition, the total radiation dose to both mother and fetus is significantly lower than with routine plain film pelvimetry. Since the procedure is quick, easy to perform and competitive in cost, CT pelvimetry should be the procedure of choice in those rare instances in which pelvimetry is indicated.
Which is the apt title for the abstract? option1: Computed tomographic pelvimetry. option2: Pain and discomfort thresholds in late pregnancy.
