Question: The answer to the question: What has been valuable for understanding social hierarchy and stratification in the earliest European societies? is inside the article: Neanderthal remains dating to around 150,000 years ago, or the Middle Paleolithic, are some of the earliest traces of human activity in the lands of modern Bulgaria. The Karanovo culture arose circa 6,500 BC and was one of several Neolithic societies in the region that thrived on agriculture. The Copper Age Varna culture (fifth millennium BC) is credited with inventing gold metallurgy. The associated Varna Necropolis treasure contains the oldest golden jewellery in the world with an approximate age of over 6,000 years. The treasure has been valuable for understanding social hierarchy and stratification in the earliest European societies.The Thracians, one of the three primary ancestral groups of modern Bulgarians, appeared on the Balkan Peninsula some time before the 12th century BC. The Thracians excelled in metallurgy and gave the Greeks the Orphean and Dionysian cults, but remained tribal and stateless. The Persian Achaemenid Empire conquered most of present-day Bulgaria in the 6th century BC and retained control over the region until 479 BC. The invasion became a catalyst for Thracian unity, and the bulk of their tribes united under king Teres to form the Odrysian kingdom in the 470s BC. It was weakened and vassalized by Philip II of Macedon in 341 BC, attacked by Celts in the 3rd century, and finally became a province of the Roman Empire in AD 45.By the end of the 1st century AD, Roman governance was established over the entire Balkan Peninsula and Christianity began spreading in the region around the 4th century. The Gothic Bible—the first Germanic language book—was created by Gothic bishop Ulfilas in what is today northern Bulgaria around 381. The region came under Byzantine control after the fall of Rome in 476. The Byzantines were engaged in prolonged warfare against Persia and could not defend their Balkan territories from barbarian incursions. This enabled the Slavs to enter the Balkan Peninsula as marauders, primarily through an area between the Danube River and the Balkan Mountains known as..., can you guess it ?

Question: The answer to the question: What are the full names of the two people who Nelle is complicating their longtime working relationship? is inside the article: Johnny O'Clock is a junior partner in a posh casino with Guido Marchettis. Complicating their longtime working relationship is Guido's wife Nelle, who is still in love with former boyfriend Johnny. She gives Johnny an expensive custom pocket watch, the twin of a birthday present she gave her husband, except Johnny's has a romantic engraving on the back. Johnny gives the watch, along with a rejection note, to Harriet Hobson, a hat-check girl at the casino, to return to Nelle. Harriet, however, apparently commits suicide using gas. Her sister Nancy shows up to find out what happened. She becomes attracted to Johnny. They eventually learn from Police Inspector Koch that Harriet was killed by poison. Harriet was dating Chuck Blayden, a crooked cop who is trying to persuade Guido to let him take Johnny's place. When Blayden also turns up dead, Koch suspects that either Johnny or Marchettis is responsible. Though Johnny tries to resist, little by little, he falls for Nancy. When Koch shows both Johnny and Marchettis Johnny's watch and note, Johnny tells Nancy their relationship is through and takes her to the airport. As he is driving away, however, he narrowly survives a drive-by shooting, and Nancy realizes he was only trying to protect her. She refuses to leave him. Johnny decides to flee to South America with Nancy, but not before brazenly cashing in his share of the casino. Marchettis pulls out a gun when Johnny's back is turned. They shoot it out; Marchettis is killed and Johnny wounded. Afterward, Nelle offers to testify it was self-defense, but only if he will come back to her. He refuses, so she tells Koch it was cold-blooded murder. Johnny's first instinct is to run away, but Nancy convinces him to give himself up., can you guess it ?
Answer: Johnny O'Clock

Question: The answer to the question: What concert tour did critics say was overproduced? is inside the article: Tonight (1984), another dance-oriented album, found Bowie collaborating with Tina Turner and, once again, Iggy Pop. It included a number of cover songs, among them the 1966 Beach Boys hit "God Only Knows". The album bore the transatlantic Top 10 hit "Blue Jean", itself the inspiration for a short film that won Bowie a Grammy Award for Best Short Form Music Video, Jazzin' for Blue Jean. Bowie performed at Wembley Stadium in 1985 for Live Aid, a multi-venue benefit concert for Ethiopian famine relief. During the event, the video for a fundraising single was premiered, Bowie's duet with Mick Jagger. "Dancing in the Street" quickly went to number one on release. The same year, Bowie worked with the Pat Metheny Group to record "This Is Not America" for the soundtrack of The Falcon and the Snowman. Released as a single, the song became a Top 40 hit in the UK and US.Bowie was given a role in the 1986 film Absolute Beginners. It was poorly received by critics, but Bowie's theme song, also named "Absolute Beginners", rose to No. 2 in the UK charts. He also appeared as Jareth, the Goblin King, in the 1986 Jim Henson film Labyrinth, for which he wrote five songs. His final solo album of the decade was 1987's Never Let Me Down, where he ditched the light sound of his previous two albums, instead offering harder rock with an industrial/techno dance edge. Peaking at No. 6 in the UK, the album yielded the hits "Day-In, Day-Out" (his 60th single), "Time Will Crawl", and "Never Let Me Down". Bowie later described it as his "nadir", calling it "an awful album". Supporting Never Let Me Down, and preceded by nine promotional press shows, the 86-concert Glass Spider Tour commenced on 30 May. Bowie's backing band included Peter Frampton on lead guitar. Contemporary critics maligned the tour as overproduced, saying it pandered to the current stadium rock trends in its special effects and dancing, although years after the tour's conclusion, critics acknowledged that the tour influenced how other artists performed concerts, including..., can you guess it ?

Glass Spider Tour
