You will be given a definition of a task first, then some input of the task.
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).

Abstract: In recent years it has become increasingly apparent that cough is frequently the sign of airway hyperreactivity. While the association between cough and wheezing is well recognized in asthmatics, cough may be the only clinical manifestation of this problem. Emergency physicians frequently have occasion to evaluate the coughing patient. Awareness of this clinical entity should facilitate appropriate evaluation, management, and referral of these patients.
Which is the apt title for the abstract? option1: Cough variant asthma [published erratum appears in Pediatr Emerg Care 1987 Mar;3(1):9] option2: Prediction and evaluation of brainstem function by auditory brainstem responses in patients with uncal herniation.
Output:
Cough variant asthma [published erratum appears in Pediatr Emerg Care 1987 Mar;3(1):9]
