This task is about writing a correct answer for the reading comprehension task. Based on the information provided in a given passage, you should identify the shortest continuous text span from the passage that serves as an answer to the given question. Avoid answers that are incorrect or provides incomplete justification for the question.

Example Input: Passage: Reflections generally affect polarization. For radio waves, one important reflector is the ionosphere which can change the wave's polarization. Thus for signals received following reflection by the ionosphere (a skywave), a consistent polarization cannot be expected. For line-of-sight communications or ground wave propagation, horizontally or vertically polarized transmissions generally remain in about the same polarization state at the receiving location. Matching the receiving antenna's polarization to that of the transmitter can make a very substantial difference in received signal strength. Question: What reflector can change the waves polarization?
Example Output: ionosphere

Example Input: Passage: The annual Southampton Boat Show is held in September each year, with over 600 exhibitors present. It runs for just over a week at Mayflower Park on the city's waterfront, where it has been held since 1968. The Boat Show itself is the climax of Sea City, which runs from April to September each year to celebrate Southampton's links with the sea. Question: In what month each year is the Southampton Boat Show held?
Example Output: September

Example Input: Passage: Under Governor Miguel Ahumada, the education system in the state was unified and brought under tighter control by the state government, and the metric system was standardized throughout the state to replace the colonial system of weights and measures. On September 16, 1897, the Civilian Hospital of Chihuahua was inaugurated in Chihuahua City and became known among the best in the country. In 1901 the Heroes Theater (Teatro de los Heroes) opened in Chihuahua City. On August 18, 1904, Governor Terrazas was replaced by Governor Enrique C. Creel. From 1907 to 1911, the Creel administration succeeded in advancing the state's legal system, modernizing the mining industry, and raising public education standards. In 1908 the Chihuahuan State Penitentiary was built, and the construction on the first large scale dam project was initiated on the Chuviscar River. During the same time, the streets of Chihuahua City were paved and numerous monuments were built in Chihuahua City and Ciudad Juarez. Question: Under which governor was the education system unified?
Example Output:
Miguel Ahumada
