Q: The 2009 and 2010 maximal depths were not confirmed by the series of dives Nereus made to the bottom during an expedition in May--June 2009. The direct descent measurements by the four expeditions which have reported from the bottom, have fixed depths in a narrow range from 10,916 m (Trieste) to 10,911 m (Kaiko), to 10,902 m (Nereus) to 10,898 m (Deepsea Challenger) Although an attempt was made to correlate locations, it could not be absolutely certain that Nereus (or the other descents) reached exactly the same points found to be maximally deep by the sonar/echo sounders of previous mapping expeditions, even though one of these echo soundings was made by Nereus' mothership.
Can we conclude that has anyone reached the bottom of challenger deep?

Q: In late 2009, the Mason City Council decided to put a measure on its 2010 ballot that would mandate a 3-percent ticket tax and a 5-percent parking tax at both Kings Island and The Beach waterpark. Council member Tony Bradburn argued that it was necessary for the city to help pay for infrastructure improvements, as well as cover police and fire expenses. This proposed tax hike was the center of debate for several months. Kings Island actively encouraged the public to write, email and call Mason City Council representatives to express opposition. On February 8, 2010, the Mason City Council voted 5--1 against the measure.
