Problem: PlayStation 3:

The 'OtherOS' functionality was not present in the updated PS Slim models, and the feature was subsequently removed from previous versions of the PS3 as part of the machine's firmware update version 3.21 which was released on April 1, 2010; Sony cited security concerns as the rationale. The firmware update 3.21 was mandatory for access to the PlayStation Network. The removal caused some controversy; as the update removed officially advertised features from already sold products, and gave rise to several class action lawsuits aimed at making Sony return the feature or provide compensation.

What functionality did the PlayStation 3 lose in version 3.21 of its firmware update?
---
A: 'OtherOS'

Context and question: Pitch is an auditory sensation in which a listener assigns musical tones to relative positions on a musical scale based primarily on their perception of the frequency of vibration. Pitch is closely related to frequency, but the two are not equivalent. Frequency is an objective, scientific attribute that can be measured. Pitch is each person's subjective perception of a sound, which cannot be directly measured. However, this does not necessarily mean that most people won't agree on which notes are higher and lower.
What type of sensation is pitch?
Answer: auditory


Question: Tucson is known for being a trailblazer in voluntary partial publicly financed campaigns. Since 1985, both mayoral and council candidates have been eligible to receive matching public funds from the city. To become eligible, council candidates must receive 200 donations of $10 or more (300 for a mayoral candidate). Candidates must then agree to spending limits equal to 33¢ for every registered Tucson voter, or $79,222 in 2005 (the corresponding figures for mayor are 64¢ per registered voter, or $142,271 in 2003). In return, candidates receive matching funds from the city at a 1:1 ratio of public money to private donations. The only other limitation is that candidates may not exceed 75% of the limit by the date of the primary. Many cities, such as San Francisco and New York City, have copied this system, albeit with more complex spending and matching formulas.
Is there an answer to this question: What is the spending limit for Tucson city council candidates to get public funding?

Answer: 33¢ for every registered Tucson voter
