Problem: The third generation began including a 30-pin dock connector, allowing for FireWire or USB connectivity. This provided better compatibility with non-Apple machines, as most of them did not have FireWire ports at the time. Eventually Apple began shipping iPods with USB cables instead of FireWire, although the latter was available separately. As of the first-generation iPod Nano and the fifth-generation iPod Classic, Apple discontinued using FireWire for data transfer (while still allowing for use of FireWire to charge the device) in an attempt to reduce cost and form factor. As of the second-generation iPod Touch and the fourth-generation iPod Nano, FireWire charging ability has been removed. The second-, third-, and fourth-generation iPod Shuffle uses a single 3.5 mm minijack phone connector which acts as both a headphone jack and a data port for the dock.
What kind of connection is provided on the iPod Shuffle for both audio output and file transfer?
The answer is the following: 3.5 mm minijack

Alloys of primarily zinc with small amounts of copper, aluminium, and magnesium are useful in die casting as well as spin casting, especially in the automotive, electrical, and hardware industries. These alloys are marketed under the name Zamak. An example of this is zinc aluminium. The low melting point together with the low viscosity of the alloy makes the production of small and intricate shapes possible. The low working temperature leads to rapid cooling of the cast products and therefore fast assembly is possible. Another alloy, marketed under the brand name Prestal, contains 78% zinc and 22% aluminium and is reported to be nearly as strong as steel but as malleable as plastic. This superplasticity of the alloy allows it to be molded using die casts made of ceramics and cement.
What is possible to produce thanks to the low melting point and low viscosity of zinc aluminium alloy?
small and intricate shapes

Input: Pain
Sugar taken orally reduces the total crying time but not the duration of the first cry in newborns undergoing a painful procedure (a single lancing of the heel). It does not moderate the effect of pain on heart rate and a recent single study found that sugar did not significantly affect pain-related electrical activity in the brains of newborns one second after the heel lance procedure. Sweet oral liquid moderately reduces the incidence and duration of crying caused by immunization injection in children between one and twelve months of age.

A sweet oral liquid does moderately reduce the incidence and duration of what?
Output: crying

Input: Article: Hard-fought battles on the Japanese home islands of Iwo Jima, Okinawa, and others resulted in horrific casualties on both sides but finally produced a Japanese defeat. Of the 117,000 Japanese troops defending Okinawa, 94 percent died. Faced with the loss of most of their experienced pilots, the Japanese increased their use of kamikaze tactics in an attempt to create unacceptably high casualties for the Allies. The U.S. Navy proposed to force a Japanese surrender through a total naval blockade and air raids.

Now answer this question: What percent of Japanese troops died on Okinawa?

Output: 94

Article: Paris' most popular sport clubs are the association football club Paris Saint-Germain F.C. and the rugby union club Stade Francais. The 80,000-seat Stade de France, built for the 1998 FIFA World Cup, is located just north of Paris in the commune of Saint-Denis. It is used for football, rugby union and track and field athletics. It hosts the French national football team for friendlies and major tournaments qualifiers, annually hosts the French national rugby team's home matches of the Six Nations Championship, and hosts several important matches of the Stade Francais rugby team. In addition to Paris Saint-Germain FC, the city has a number of other amateur football clubs: Paris FC, Red Star, RCF Paris and Stade Francais Paris.

Question: How many seats are in the State de France?
Ans: 80,000

Input: Black people
By that time, the majority of black people in the United States were native-born, so the use of the term "African" became problematic. Though initially a source of pride, many blacks feared that the use of African as an identity would be a hindrance to their fight for full citizenship in the US. They also felt that it would give ammunition to those who were advocating repatriating black people back to Africa. In 1835, black leaders called upon Black Americans to remove the title of "African" from their institutions and replace it with "Negro" or "Colored American". A few institutions chose to keep their historic names, such as the African Methodist Episcopal Church. African Americans popularly used the terms "Negro" or "colored" for themselves until the late 1960s.

Why did the use of "African" become an issue?
Output:
the majority of black people in the United States were native-born
