Input: Mosaic
Christian mosaic art also flourished in Rome, gradually declining as conditions became more difficult in the Early Middle Ages. 5th century mosaics can be found over the triumphal arch and in the nave of the basilica of Santa Maria Maggiore. The 27 surviving panels of the nave are the most important mosaic cycle in Rome of this period. Two other important 5th century mosaics are lost but we know them from 17th-century drawings. In the apse mosaic of Sant'Agata dei Goti (462–472, destroyed in 1589) Christ was seated on a globe with the twelve Apostles flanking him, six on either side. At Sant'Andrea in Catabarbara (468–483, destroyed in 1686) Christ appeared in the center, flanked on either side by three Apostles. Four streams flowed from the little mountain supporting Christ. The original 5th-century apse mosaic of the Santa Sabina was replaced by a very similar fresco by Taddeo Zuccari in 1559. The composition probably remained unchanged: Christ flanked by male and female saints, seated on a hill while lambs drinking from a stream at its feet. All three mosaics had a similar iconography.

What was similar between the three most important 5th century mosaics?
Output: iconography

Input: Solar energy
Commercial CSP plants were first developed in the 1980s. Since 1985 the eventually 354 MW SEGS CSP installation, in the Mojave Desert of California, is the largest solar power plant in the world. Other large CSP plants include the 150 MW Solnova Solar Power Station and the 100 MW Andasol solar power station, both in Spain. The 250 MW Agua Caliente Solar Project, in the United States, and the 221 MW Charanka Solar Park in India, are the world’s largest photovoltaic plants. Solar projects exceeding 1 GW are being developed, but most of the deployed photovoltaics are in small rooftop arrays of less than 5 kW, which are grid connected using net metering and/or a feed-in tariff. In 2013 solar generated less than 1% of the worlds total grid electricity.

Where is the largest solar power plant in the world located?
Output: Mojave Desert of California

Input: The Sun (United Kingdom)
Television personality Piers Morgan, a former editor of the Daily Mirror and of The Sun's Bizarre pop column, has said that during the late 1980s, at Kelvin MacKenzie's behest, he was ordered to speculate on the sexuality of male pop stars for a feature headlined "The Poofs of Pop". He also recalls MacKenzie headlining a January 1989 story about the first same-sex kiss on the BBC television soap opera EastEnders "EastBenders", describing the kiss between Colin Russell and Guido Smith as "a homosexual love scene between yuppie poofs ... when millions of children were watching".

What did Piers Morgan offer opinions about in a late 1980s column?
