Problem: Macintosh:

Starting in 2006, Apple's industrial design shifted to favor aluminum, which was used in the construction of the first MacBook Pro. Glass was added in 2008 with the introduction of the unibody MacBook Pro. These materials are billed as environmentally friendly. The iMac, MacBook Pro, MacBook Air, and Mac Mini lines currently all use aluminum enclosures, and are now made of a single unibody. Chief designer Jonathan Ive continues to guide products towards a minimalist and simple feel, including eliminating of replaceable batteries in notebooks. Multi-touch gestures from the iPhone's interface have been applied to the Mac line in the form of touch pads on notebooks and the Magic Mouse and Magic Trackpad for desktops.

When did Apple begin to favor aluminum in their design?

Problem: The Standard Output Sensitivity (SOS) technique, also new in the 2006 version of the standard, effectively specifies that the average level in the sRGB image must be 18% gray plus or minus 1/3 stop when the exposure is controlled by an automatic exposure control system calibrated per ISO 2721 and set to the EI with no exposure compensation. Because the output level is measured in the sRGB output from the camera, it is only applicable to sRGB imagestypically JPEGand not to output files in raw image format. It is not applicable when multi-zone metering is used.
What technique was removed in the 2006 standards?

In 2005 two city council members, Ralph Inzunza and Deputy Mayor Michael Zucchet who briefly took over as acting mayor when Murphy resigned were convicted of extortion, wire fraud, and conspiracy to commit wire fraud for taking campaign contributions from a strip club owner and his associates, allegedly in exchange for trying to repeal the city's "no touch" laws at strip clubs. Both subsequently resigned. Inzunza was sentenced to 21 months in prison. In 2009, a judge acquitted Zucchet on seven out of the nine counts against him, and granted his petition for a new trial on the other two charges; the remaining charges were eventually dropped.
Who did Inzunza and Zucche reject money from?
A: unanswerable

Context and question: During August and September 2004, there was an intense focus on events that occurred in the late 1960s and early 1970s. Bush was accused of failing to fulfill his required service in the Texas Air National Guard. However, the focus quickly shifted to the conduct of CBS News after they aired a segment on 60 Minutes Wednesday introducing what became known as the Killian documents. Serious doubts about the documents' authenticity quickly emerged, leading CBS to appoint a review panel that eventually resulted in the firing of the news producer and other significant staffing changes.
What did the Texas Air National Guard focus on in September 2004?
Answer: unanswerable

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: Other than the Silver Proof set, what other type of Proof set exists?

Answer: Presidential Dollar Proof Set

Seen in its wider social context, Greek Revival architecture sounded a new note of sobriety and restraint in public buildings in Britain around 1800 as an assertion of nationalism attendant on the Act of Union, the Napoleonic Wars, and the clamour for political reform. It was to be William Wilkins's winning design for the public competition for Downing College, Cambridge that announced the Greek style was to be the dominant idiom in architecture. Wilkins and Robert Smirke went on to build some of the most important buildings of the era, including the Theatre Royal, Covent Garden (180809), the General Post Office (182429) and the British Museum (182348), Wilkins University College London (182630) and the National Gallery (183238). In Scotland, Thomas Hamilton (17841858), in collaboration with the artists Andrew Wilson (17801848) and Hugh William Williams (17731829) created monuments and buildings of international significance; the Burns Monument at Alloway (1818) and the (Royal) High School in Edinburgh (182329).
Whose winning design for public competition began the dominance of Greek style architecture?
A:
William Wilkins
