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.

Example Input: Sentence: iPods have been criticized for alleged short life-span and fragile hard drives. A 2005 survey conducted on the MacInTouch website found that the iPod line had an average failure rate of 13.7% (although they note that comments from respondents indicate that "the true iPod failure rate may be lower than it appears"). It concluded that some models were more durable than others. In particular, failure rates for iPods employing hard drives was usually above 20% while those with flash memory had a failure rate below 10%. In late 2005, many users complained that the surface of the first generation iPod Nano can become scratched easily, rendering the screen unusable. A class action lawsuit was also filed. Apple initially considered the issue a minor defect, but later began shipping these iPods with protective sleeves.[citation needed]
Question: What website ran a survey to learn how often iPods ceased working?
Example Output: MacInTouch

Example Input: Sentence: DST's clock shifts have the obvious disadvantage of complexity. People must remember to change their clocks; this can be time-consuming, particularly for mechanical clocks that cannot be moved backward safely. People who work across time zone boundaries need to keep track of multiple DST rules, as not all locations observe DST or observe it the same way. The length of the calendar day becomes variable; it is no longer always 24 hours. Disruption to meetings, travel, broadcasts, billing systems, and records management is common, and can be expensive. During an autumn transition from 02:00 to 01:00, a clock reads times from 01:00:00 through 01:59:59 twice, possibly leading to confusion.
Question: During the fall time shift from 02:00 to 01:00, how many times will a clock show the times between 01:00:00 and 01:59:59?
Example Output: twice

Example Input: Sentence: On 2 March 1979, the GPC announced the separation of government and revolution, the latter being represented by new Revolutionary Committees, who operated in tandem with the People's Committees in schools, universities, unions, the police force and the military. Dominated by revolutionary zealots, the Revolutionary Committees were led by Mohammad Maghgoub and a Central Coordinating Office, and met with Gaddafi annually. Publishing a weekly magazine The Green March (al-Zahf al-Akhdar), in October 1980 they took control of the press. Responsible for perpetuating revolutionary fervour, they performed ideological surveillance, later adopting a significant security role, making arrests and putting people on trial according to the "law of the revolution" (qanun al-thawra). With no legal code or safeguards, the administration of revolutionary justice was largely arbitrary and resulted in widespread abuses and the suppression of civil liberties: the "Green Terror."
Question: How often was al-Zahf al-Akhdar published?
Example Output:
weekly
