Problem: Theophrastus wrote some of the earliest descriptions of plants and animals, establishing the first taxonomy and looking at minerals in terms of their properties such as hardness. Pliny the Elder produced what is one of the largest encyclopedias of the natural world in 77 AD, and must be regarded as the rightful successor to Theophrastus. For example, he accurately describes the octahedral shape of the diamond, and proceeds to mention that diamond dust is used by engravers to cut and polish other gems owing to its great hardness. His recognition of the importance of crystal shape is a precursor to modern crystallography, while mention of numerous other minerals presages mineralogy. He also recognises that other minerals have characteristic crystal shapes, but in one example, confuses the crystal habit with the work of lapidaries. He was also the first to recognise that amber was a fossilized resin from pine trees because he had seen samples with trapped insects within them.
What characteristic was Pliny the Elder the first to recognize about amber?
The answer is the following: was a fossilized resin

Problem: Non-religious Umayyad mosaic works were mainly floor panels which decorated the palaces of the caliphs and other high-ranking officials. They were closely modeled after the mosaics of the Roman country villas, once common in the Eastern Mediterranean. The most superb example can be found in the bath house of Hisham's Palace, Palestine which was made around 744. The main panel depicts a large tree and underneath it a lion attacking a deer (right side) and two deers peacefully grazing (left side). The panel probably represents good and bad governance. Mosaics with classical geometric motifs survived in the bath area of the 8th-century Umayyad palace complex in Anjar, Lebanon. The luxurious desert residence of Al-Walid II in Qasr al-Hallabat (in present-day Jordan) was also decorated with floor mosaics that show a high level of technical skill. The best preserved panel at Hallabat is divided by a Tree of Life flanked by "good" animals on one side and "bad" animals on the other. Among the Hallabat representations are vine scrolls, grapes, pomegranates, oryx, wolves, hares, a leopard, pairs of partridges, fish, bulls, ostriches, rabbits, rams, goats, lions and a snake. At Qastal, near Amman, excavations in 2000 uncovered the earliest known Umayyad mosaics in present-day Jordan, dating probably from the caliphate of Abd al-Malik ibn Marwan (685705). They cover much of the floor of a finely decorated building that probably served as the palace of a local governor. The Qastal mosaics depict geometrical patterns, trees, animals, fruits and rosettes. Except for the open courtyard, entrance and staircases, the floors of the entire palace were covered in mosaics.
Where can the most superb example of Umayyad mosaic floor paneling?
The answer is the following: the bath house of Hisham's Palace

Problem: In the early 1980s, Downtown Manhattan's no wave scene transitioned from its abrasive origins into a more dance-oriented sound, with compilations such as ZE's Mutant Disco (1981) highlighting a newly playful sensibility borne out of the city's clash of hip hop, disco and punk styles, as well as dub reggae and world music influences. Artists such as Liquid Liquid, the B-52s, Cristina, Arthur Russell, James White and the Blacks and Lizzy Mercier Descloux pursued a formula described by Luc Sante as "anything at all + disco bottom". The decadent parties and art installations of venues such as Club 57 and the Mudd Club became cultural hubs for musicians and visual artists alike, with figures such as Jean-Michel Basquiat, Keith Haring and Michael Holman frequenting the scene. Other no wave-indebted groups such as Swans, Glenn Branca, the Lounge Lizards, Bush Tetras and Sonic Youth instead continued exploring the early scene's forays into noise and more abrasive territory.
Who did the venues because cultural hubs for?
The answer is the following: musicians and visual artists alike

Problem: In July 1943, as a result of the American Federation of Musicians boycott of US recording studios, the a cappella vocal group The Song Spinners had a best-seller with "Comin' In On A Wing And A Prayer". In the 1950s several recording groups, notably The Hi-Los and the Four Freshmen, introduced complex jazz harmonies to a cappella performances. The King's Singers are credited with promoting interest in small-group a cappella performances in the 1960s. In 1983 an a cappella group known as The Flying Pickets had a Christmas 'number one' in the UK with a cover of Yazoo's (known in the US as Yaz) "Only You". A cappella music attained renewed prominence from the late 1980s onward, spurred by the success of Top 40 recordings by artists such as The Manhattan Transfer, Bobby McFerrin, Huey Lewis and the News, All-4-One, The Nylons, Backstreet Boys and Boyz II Men.[citation needed]
What number one song was covered by an a cappella group in 1983?
The answer is the following:
"Only You"
