Problem: Paul VI opened the third period on 14 September 1964, telling the Council Fathers that he viewed the text about the Church as the most important document to come out from the Council. As the Council discussed the role of bishops in the papacy, Paul VI issued an explanatory note confirming the primacy of the papacy, a step which was viewed by some as meddling in the affairs of the Council American bishops pushed for a speedy resolution on religious freedom, but Paul VI insisted this to be approved together with related texts such as ecumenism. The Pope concluded the session on 21 November 1964, with the formal pronouncement of Mary as Mother of the Church.

The creation of a unified German Empire ended the balance of power that had been created with the Congress of Vienna after the end of the Napoleonic Wars. Germany had established itself as the main power in continental Europe with the most powerful and professional army in the world.[citation needed] Although Great Britain remained the dominant world power, British involvement in European affairs during the late 19th century was very limited, allowing Germany to exercise great influence over the European mainland.[citation needed] Besides, the Crown Prince's marriage with the daughter of Queen Victoria was only the most prominent of several GermanBritish relationships.
British involvement in European matters in the late 19th century was considered what?
very limited

Input: Article: The opening years of the 1980s saw a number of changes in personnel and direction of established hard rock acts, including the deaths of Bon Scott, the lead singer of AC/DC, and John Bonham, drummer with Led Zeppelin. Whereas Zeppelin broke up almost immediately afterwards, AC/DC pressed on, recording the album Back in Black (1980) with their new lead singer, Brian Johnson. It became the fifth-highest-selling album of all time in the US and the second-highest-selling album in the world. Black Sabbath had split with original singer Ozzy Osbourne in 1979 and replaced him with Ronnie James Dio, formerly of Rainbow, giving the band a new sound and a period of creativity and popularity beginning with Heaven and Hell (1980). Osbourne embarked on a solo career with Blizzard of Ozz (1980), featuring American guitarist Randy Rhoads. Some bands, such as Queen, moved away from their hard rock roots and more towards pop rock, while others, including Rush with Moving Pictures (1981), began to return to a hard rock sound. The creation of thrash metal, which mixed heavy metal with elements of hardcore punk from about 1982, particularly by Metallica, Anthrax, Megadeth and Slayer, helped to create extreme metal and further remove the style from hard rock, although a number of these bands or their members would continue to record some songs closer to a hard rock sound. Kiss moved away from their hard rock roots toward pop metal: firstly removing their makeup in 1983 for their Lick It Up album, and then adopting the visual and sound of glam metal for their 1984 release, Animalize, both of which marked a return to commercial success. Pat Benatar was one of the first women to achieve commercial success in hard rock, with three successive Top 5 albums between 1980 and 1982.

Now answer this question: Who was the original lead singer of AC/DC who died?

Output: Bon Scott

Article: On April 18, 1985, a few months after taking his Senate seat, Kerry and Senator Tom Harkin of Iowa traveled to Nicaragua and met the country's president, Daniel Ortega. Though Ortega had won internationally certified elections, the trip was criticized because Ortega and his leftist Sandinista government had strong ties to Cuba and the USSR and were accused of human rights abuses. The Sandinista government was opposed by the right-wing CIA-backed rebels known as the Contras. While in Nicaragua, Kerry and Harkin talked to people on both sides of the conflict. Through the senators, Ortega offered a cease-fire agreement in exchange for the U.S. dropping support of the Contras. The offer was denounced by the Reagan administration as a "propaganda initiative" designed to influence a House vote on a $14 million Contra aid package, but Kerry said "I am willing..... to take the risk in the effort to put to test the good faith of the Sandinistas." The House voted down the Contra aid, but Ortega flew to Moscow to accept a $200 million loan the next day, which in part prompted the House to pass a larger $27 million aid package six weeks later.

Question: Who did Kerry visit Nicaragua with?
Ans: Senator Tom Harkin

Input: Biodiversity
The age of the Earth is about 4.54 billion years old. The earliest undisputed evidence of life on Earth dates at least from 3.5 billion years ago, during the Eoarchean Era after a geological crust started to solidify following the earlier molten Hadean Eon. There are microbial mat fossils found in 3.48 billion-year-old sandstone discovered in Western Australia. Other early physical evidence of a biogenic substance is graphite in 3.7 billion-year-old metasedimentary rocks discovered in Western Greenland. More recently, in 2015, "remains of biotic life" were found in 4.1 billion-year-old rocks in Western Australia. According to one of the researchers, "If life arose relatively quickly on Earth ... then it could be common in the universe."

Where were the 3.7 billion-year-old metasedimentary rocks discovered?
Output:
Western Greenland
