Given a question and a context passage, generate the answer having the word or phrase from the context passage. Here, the answer should be a shortest continous span from the passage.
Example: Context: Architecturally, the school has a Catholic character. Atop the Main Building's gold dome is a golden statue of the Virgin Mary. Immediately in front of the Main Building and facing it, is a copper statue of Christ with arms upraised with the legend 'Venite Ad Me Omnes'. Next to the Main Building is the Basilica of the Sacred Heart. Immediately behind the basilica is the Grotto, a Marian place of prayer and reflection. It is a replica of the grotto at Lourdes, France where the Virgin Mary reputedly appeared to Saint Bernadette Soubirous in 1858. At the end of the main drive (and in a direct line that connects through 3 statues and the Gold Dome), is a simple, modern stone statue of Mary.
Question: To whom did the Virgin Mary allegedly appear in 1858 in Lourdes France?
Example solution: Saint Bernadette Soubirous
Example explanation: This is the correct answer. Because the question is asking for the name of the person and following sentence from the passage answers it: It is a replica of the grotto at Lourdes, France where the Virgin Mary reputedly appeared to Saint Bernadette Soubirous in 1858.

Problem: Context: Flumazenil (Ro 15-1788) proved to be a very efficacious competitive antagonist of benzodiazepines that reliably counteracts their pharmacological actions within 1-2 min as could be demonstrated in clinical and EEG studies. In general, a total dose of 0.3-0.8 mg will be sufficient in clinical practice, avoiding side effects like nausea, tremor, sweating, or transient anxiety that could be observed when higher dosages were administered. Its therapeutic range is very high as could be demonstrated in experimental animal in which up to 8.000-fold the clinical dose was administered. The total volume of distribution (Vdes) amounts to nearly 1.000 ml/kg BW and the total clearance exceeds 1.200 ml/min, resulting in a biological half-life of less than 60 min. According to the benzodiazepine dosage and the rapid plasma concentration decline of flumazenil, in some cases a resedation could be observed. Hence, a careful observation of the antagonised patient on the ward is mandatory for 1.5-2 h, even if at first sight the antagonization seemed successful and the patient fully awake and cooperative. In anaesthesia, indications to administer flumazenil are adverse drug reactions and prolonged recovery after adequate benzodiazepine dosage. In intensive care medicine, the antagonist may be used in the treatment of benzodiazepine overdose as well as in the differential diagnosis of a coma of unknown origin. Additionally, the antagonist may be administered to interrupt benzodiazepine sedation e.g. for neurological examination.
Question: Which drug should be used as an antidote in benzodiazepine overdose?
Solution: flumazenil
