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: The course of a pregnant patient at term who was acutely exposed to carbon monoxide is described. A review of the fetal-maternal carboxyhemoglobin relationships and the differences in fetal oxyhemoglobin physiology are used to explain the recommendation that pregnant women with carbon monoxide poisoning should receive 100% oxygen therapy for up to five times longer than is otherwise necessary. The role of hyperbaric oxygen therapy is considered.
Which is the apt title for the abstract? option1: Acute carbon monoxide poisoning during pregnancy. option2: Immune haemolytic anaemia and nomifensine treatment in north west England 1984-85: report of six cases.
[EX A]: Acute carbon monoxide poisoning during pregnancy.

[EX Q]: Abstract: An emergency environmental health investigation of a mass poisoning of unknown origin is a multidiscipline effort that requires the cooperation and close communication of epidemiologists, toxicologists, and chemists. The laboratory's role in this effort is important; special instruments, knowledge, and experience are needed. Our approach to such an investigation is discussed and past cases are used as illustrations. The role of the analytical chemist is presented, and the major resources needed for these investigations are described.
Which is the apt title for the abstract? option1: The laboratory's role in environmental health emergency investigations. option2: Selective screening device for the early detection of normal or delayed cognitive development in infants at risk for later mental retardation.
[EX A]: The laboratory's role in environmental health emergency investigations.

[EX Q]: Abstract: Lymphoscintigraphy with Technetium antimony sulfur colloid (TASC) was used in four patients with malignant melanoma to identify the pattern of lymphatic drainage, allowing selective lymph node dissection. TASC is safe and predictive of lymph node drainage patterns. Using this technique allows visualization of multiple tiers of lymph nodes in 2 to 6 hours.
Which is the apt title for the abstract? option1: Technetium antimony sulfur colloid scintiscan in selective lymph node dissection for malignant melanoma. option2: Pins for the neurologic examination [letter]
[EX A]:
Technetium antimony sulfur colloid scintiscan in selective lymph node dissection for malignant melanoma.
