In this task, you're given passages that contain mentions of a time duration related quesry and we are supposed to write answer to a question that involves event "frequency", which refers to how often an event is likely to be repeated. For example, "taking showers" typically occurs ~5 times a week, "going to saturday market" usually happens every few weeks/months, etc.
Note that a lot of the questions could have more than one correct answers. We only need a single most-likely answer. Please try to keep your "answer" as simple as possible. Concise and simple "answer" is preferred over those complex and verbose ones.

Sentence: The University of Kansas has had more teams (70) compete in the National Debate Tournament than any other university. Kansas has won the tournament 5 times (1954, 1970, 1976, 1983, and 2009) and had 12 teams make it to the final four. Kansas trails only Northwestern (13), Dartmouth (6), and Harvard (6) for most tournaments won. Kansas also won the 198182 Copeland Award.

Sentence: Problems with the 10NES lockout chip frequently resulted in the console's most infamous problem: the blinking red power light, in which the system appears to turn itself on and off repeatedly because the 10NES would reset the console once per second. The lockout chip required constant communication with the chip in the game to work. Dirty, aging and bent connectors would often disrupt the communication, resulting in the blink effect. Alternatively, the console would turn on but only show a solid white, gray, or green screen. Users attempted to solve this problem by blowing air onto the cartridge connectors, inserting the cartridge just far enough to get the ZIF to lower, licking the edge connector, slapping the side of the system after inserting a cartridge, shifting the cartridge from side to side after insertion, pushing the ZIF up and down repeatedly, holding the ZIF down lower than it should have been, and cleaning the connectors with alcohol. These attempted solutions often became notable in their own right and are often remembered alongside the NES. Many of the most frequent attempts to fix this problem instead ran the risk of damaging the cartridge and/or system.[citation needed] In 1989, Nintendo released an official NES Cleaning Kit to help users clean malfunctioning cartridges and consoles.
Question: The 10NES would reset the system how often?
once per second

Sentence: About 1.7 to 5 billion cases of diarrhea occur per year. It is most common in developing countries, where young children get diarrhea on average three times a year. Total deaths from diarrhea are estimated at 1.26 million in 2013 down from 2.58 million in 1990. In 2012, it is the second most common cause of deaths in children younger than five (0.76 million or 11%). Frequent episodes of diarrhea are also a common cause of malnutrition and the most common cause in those younger than five years of age. Other long term problems that can result include stunted growth and poor intellectual development.
Question: How often do kids get diarrhea in developing countries?
average three times a year
