 Question: has maroon 5 ever performed at the super bowl Context: Roman dates were counted inclusively forward to the next of three principal days: the first of the month (the kalends), a day less than the middle of the month (the ides), and eight days--nine, counting inclusively--before this (the nones). The original calendar consisted of 10 months beginning in spring with March; winter was left as an unassigned span of days. These months ran for 38 nundinal cycles, each forming a kind of eight (i.e., ``nine'') day week ended by religious rituals and a public market. The winter period was later divided into two months, January and February. The legendary early kings Romulus and Numa were traditionally credited with establishing this early fixed calendar, which bears traces of its origin as an observational lunar one. In particular, the kalends, nones, and ides seem to have derived from the first sighting of the crescent moon, the first-quarter moon, and the full moon respectively. The system ran well short of the solar year, and it needed constant intercalation to keep religious festivals and other activities in their proper seasons. For superstitious reasons, such intercalation occurred within the month of February even after it was no longer considered the last month.
 Question: was there only 10 months in a year Context: Group F of the 2018 FIFA World Cup took place from 17 to 27 June 2018. The group consisted of Germany, Mexico, Sweden, and South Korea. Sweden and Mexico were the top two teams that advanced to the round of 16. The incumbent World Cup champions, Germany, placed last, making it the first time since 1938 that the Germans did not advance beyond the first round, and the first time ever, the group stage. The early German exit was ``greeted with shock in newspapers around the world''.
 Question: is germany in the fifa world cup 2018 Context: The Crown Estate is a collection of lands and holdings in the United Kingdom belonging to the British monarch as a corporation sole, making it the ``Sovereign's public estate'', which is neither government property nor part of the monarch's private estate. As a result of this arrangement, the sovereign is not involved with the management or administration of the estate, exercising only very limited control of its affairs. Instead, the estate's extensive portfolio is overseen by a semi-independent, incorporated public body headed by the Crown Estate Commissioners, who exercise ``the powers of ownership'' of the estate, although they are not ``owners in their own right''. The revenues from these hereditary possessions have been placed by the monarch at the disposition of Her Majesty's Government in exchange for relief from the responsibility to fund the Civil Government and thus proceed directly to Her Majesty's Treasury, for the benefit of the British nation. The Crown Estate is formally accountable to the Parliament of the United Kingdom, where it is legally mandated to make an annual report to the sovereign, a copy of which is forwarded to the House of Commons.
