Input: Read this: At the time the store was introduced, purchased audio files used the AAC format with added encryption, based on the FairPlay DRM system. Up to five authorized computers and an unlimited number of iPods could play the files. Burning the files with iTunes as an audio CD, then re-importing would create music files without the DRM. The DRM could also be removed using third-party software. However, in a deal with Apple, EMI began selling DRM-free, higher-quality songs on the iTunes Stores, in a category called "iTunes Plus." While individual songs were made available at a cost of US$1.29, 30¢ more than the cost of a regular DRM song, entire albums were available for the same price, US$9.99, as DRM encoded albums. On October 17, 2007, Apple lowered the cost of individual iTunes Plus songs to US$0.99 per song, the same as DRM encoded tracks. On January 6, 2009, Apple announced that DRM has been removed from 80% of the music catalog, and that it would be removed from all music by April 2009.
Question: In what category could files without digital rights management be found on the iTunes store?

Output: iTunes Plus


QUES: Complex serological techniques have been developed into what are known as Immunoassays. Immunoassays can use the basic antibody – antigen binding as the basis to produce an electro - magnetic or particle radiation signal, which can be detected by some form of instrumentation. Signal of unknowns can be compared to that of standards allowing quantitation of the target antigen. To aid in the diagnosis of infectious diseases, immunoassays can detect or measure antigens from either infectious agents or proteins generated by an infected organism in response to a foreign agent. For example, immunoassay A may detect the presence of a surface protein from a virus particle. Immunoassay B on the other hand may detect or measure antibodies produced by an organism's immune system that are made to neutralize and allow the destruction of the virus.

What type of proteins are undetectable by Immunoassays?
What is the answer?

QUES: The JEDEC EIA370 transistor device numbers usually start with "2N", indicating a three-terminal device (dual-gate field-effect transistors are four-terminal devices, so begin with 3N), then a 2, 3 or 4-digit sequential number with no significance as to device properties (although early devices with low numbers tend to be germanium). For example, 2N3055 is a silicon n–p–n power transistor, 2N1301 is a p–n–p germanium switching transistor. A letter suffix (such as "A") is sometimes used to indicate a newer variant, but rarely gain groupings.
Which devices usually have the shortest transistor device numbers?

The city's first bus rapid transit line, the Metrobús, began operation in June 2005, along Avenida Insurgentes. Line 2 opened in December 2008, serving Eje 4 Sur, line 3 opened in February 2011, serving Eje 1 Poniente, and line 4 opened in April 2012 connecting the airport with San Lázaro and Buenavista Station at Insurgentes. As the microbuses were removed from its route, it was hoped that the Metrobús could reduce pollution and decrease transit time for passengers. In June 2013, Mexico City's mayor announced two more lines to come: Line 5 serving Eje 3 Oriente and Line 6 serving Eje 5 Norte. As of June 2013, 367 Metrobús buses transported 850,000 passengers daily.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When did the second line of Metrobus open?
Ah, so.. December 2008


Question: In 1988, with that preliminary phase of the project completed, Professor Skousen took over as editor and head of the FARMS Critical Text of the Book of Mormon Project and proceeded to gather still scattered fragments of the Original Manuscript of the Book of Mormon and to have advanced photographic techniques applied to obtain fine readings from otherwise unreadable pages and fragments. He also closely examined the Printer’s Manuscript (owned by the Community of Christ—RLDS Church in Independence, Missouri) for differences in types of ink or pencil, in order to determine when and by whom they were made. He also collated the various editions of the Book of Mormon down to the present to see what sorts of changes have been made through time.
Try to answer this question if possible: Professor Skousen left what position in 1988?
Answer: unanswerable


QUES: Dannatt criticised a remnant "Cold War mentality", with military expenditures based on retaining a capability against a direct conventional strategic threat; He said currently only 10% of the MoD's equipment programme budget between 2003 and 2018 was to be invested in the "land environment"—at a time when Britain was engaged in land-based wars in Afghanistan and Iraq.
What is it called when Iraq was criticized for their military budget to stop a threat?
