Question: Beyonce is believed to have first started a relationship with Jay Z after a collaboration on "'03 Bonnie & Clyde", which appeared on his seventh album The Blueprint 2: The Gift & The Curse (2002). Beyonce appeared as Jay Z's girlfriend in the music video for the song, which would further fuel speculation of their relationship. On April 4, 2008, Beyonce and Jay Z were married without publicity.

Question: Within the past ten years, the amount of social networking sites available to the public has greatly increased as well as the number of adolescents using them. Several sources report a high proportion of adolescents who use social media: 73% of 1217 year olds reported having at least one social networking profile; two-thirds (68%) of teens text every day, half (51%) visit social networking sites daily, and 11% send or receive tweets at least once every day. In fact, more than a third (34%) of teens visit their main social networking site several times a day. One in four (23%) teens are "heavy" social media users, meaning they use at least two different types of social media each and every day.
Is there an answer to this question: What ratio of teens are "heavy" social media users, using two types of media daily?

Answer: One in four (23%)

Question: The United States Mint produces Proof Sets specifically for collectors and speculators. Silver Proofs tend to be the standard designs but with the dime, quarter, and half dollar containing 90% silver. Starting in 1983 and ending in 1997, the Mint also produced proof sets containing the year's commemorative coins alongside the regular coins. Another type of proof set is the Presidential Dollar Proof Set where four special $1 coins are minted each year featuring a president. Because of budget constraints and increasing stockpiles of these relatively unpopular coins, the production of new Presidential dollar coins for circulation was suspended on December 13, 2011, by U.S. Treasury Secretary Timothy F. Geithner. Future minting of such coins will be made solely for collectors.
Is there an answer to this question: When did the Mint begin producing budget sets?
