Problem: On 30 September 1915, troops of the Serbian Army observed three enemy aircraft approaching Kragujevac. Soldiers shot at them with shotguns and machine-guns but failed to prevent them from dropping 45 bombs over the city, hitting military installations, the railway station and many other, mostly civilian, targets in the city. During the bombing raid, private Radoje Ljutovac fired his cannon at the enemy aircraft and successfully shot one down. It crashed in the city and both pilots died from their injuries. The cannon Ljutovac used was not designed as an anti-aircraft gun, it was a slightly modified Turkish cannon captured during the First Balkan War in 1912. This was the first occasion in military history that a military aircraft was shot down with ground-to-air fire.

Problem: Termed "the acoustic equivalent to Prozac", soft adult contemporary, a more adult-oriented version of AC, was born in the late 1970s and grew in the early 1980s. WEEI-FM in Boston was the first station to use the term "soft rock", with ad slogans such as, "Fleetwood Mac ... without the yack" and "Joni ... without the baloney". The vast majority of music played on soft AC stations is mellow, more acoustic, and primarily solo vocalists.
What decade saw the birth of the soft adult contemporary format?

Answer: 1970s


Problem: The biographical tradition asserts that Virgil began the hexameter Eclogues (or Bucolics) in 42 BC and it is thought that the collection was published around 39–38 BC, although this is controversial. The Eclogues (from the Greek for "selections") are a group of ten poems roughly modeled on the bucolic hexameter poetry ("pastoral poetry") of the Hellenistic poet Theocritus. After his victory in the Battle of Philippi in 42 BC, fought against the army led by the assassins of Julius Caesar, Octavian tried to pay off his veterans with land expropriated from towns in northern Italy, supposedly including, according to the tradition, an estate near Mantua belonging to Virgil. The loss of his family farm and the attempt through poetic petitions to regain his property have traditionally been seen as Virgil's motives in the composition of the Eclogues. This is now thought to be an unsupported inference from interpretations of the Eclogues. In Eclogues 1 and 9, Virgil indeed dramatizes the contrasting feelings caused by the brutality of the land expropriations through pastoral idiom, but offers no indisputable evidence of the supposed biographic incident. While some readers have identified the poet himself with various characters and their vicissitudes, whether gratitude by an old rustic to a new god (Ecl. 1), frustrated love by a rustic singer for a distant boy (his master's pet, Ecl. 2), or a master singer's claim to have composed several eclogues (Ecl. 5), modern scholars largely reject such efforts to garner biographical details from works of fiction, preferring to interpret an author's characters and themes as illustrations of contemporary life and thought. The ten Eclogues present traditional pastoral themes with a fresh perspective. Eclogues 1 and 9 address the land confiscations and their effects on the Italian countryside. 2 and 3 are pastoral and erotic, discussing both homosexual love (Ecl. 2) and attraction toward people of any gender (Ecl. 3). Eclogue 4, addressed to Asinius Pollio, the so-called "Messianic Eclogue" uses the imagery of the golden age in connection with the birth of a child (who the child was meant to be has been subject to debate). 5 and 8 describe the myth of Daphnis in a song contest, 6, the cosmic and mythological song of Silenus; 7, a heated poetic contest, and 10 the sufferings of the contemporary elegiac poet Cornelius Gallus. Virgil is credited[by whom?] in the Eclogues with establishing Arcadia as a poetic ideal that still resonates in Western literature and visual arts and setting the stage for the development of Latin pastoral by Calpurnius Siculus, Nemesianus, and later writers.
