Student A:In Lent, many Christians commit to fasting, as well as giving up certain luxuries in order to replicate the sacrifice of Jesus Christ's journey into the desert for 40 days. Many Christians also add a Lenten spiritual discipline, such as reading a daily devotional or praying through a Lenten calendar, to draw themselves near to God. The Stations of the Cross, a devotional commemoration of Christ's carrying the Cross and of his execution, are often observed. Many Roman Catholic and some Protestant churches remove flowers from their altars, while crucifixes, religious statues, and other elaborate religious symbols are often veiled in violet fabrics in solemn observance of the event. Throughout Christendom, some adherents mark the season with the traditional abstention from the consumption of meat, most notably among Lutherans, Roman Catholics and Anglicans.

Problem:Context: On February 7, 1973, the United States Senate voted 77-to-0 to approve Senate Resolution S. Res. 60 and establish a select committee to investigate Watergate, with Sam Ervin named chairman the next day. The hearings held by the Senate committee, in which Dean and other former administration officials testified, were broadcast from May 17 to August 7, 1973.

Problem:The company's ads sometimes focus on its reptilian mascot, The Gecko, an anthropomorphic Day Gecko created by The Martin Agency, modified in 2005 to a CGI character by Animation Director David Hulin and his team at Framestore. The gecko first appeared in 1999, during the Screen Actors Guild strike that prevented the use of live actors. The original commercial features the Gecko, voiced by actor Kelsey Grammer, who climbs onto a microphone on a podium and utters "This is my final plea: I am a gecko, not to be confused with GEICO, which could save you hundreds on car insurance. So, STOP CALLING ME!", before licking his eye. Later "wrong number" ads used Dave Kelly as the voice of the gecko. In the subsequent commercials with Jake Wood (which portray him as a representative of the company), the gecko speaks with a British Cockney accent, because it would be unexpected, according to Martin Agency's Steve Bassett. In 2010s commercials, the gecko's accent is more working-class, perhaps in an effort to further "humanize" him. "As computer animation got better and as we got to know the character better, we did a few things," says Steve Bassett, creative director at The Martin Agency. "We wanted to make him a little more guy-next-door. And he looks a lot more real than he's looked before." Chelsea Clinton, daughter of former president Bill Clinton and then-Secretary of State and 2016 Democratic Presidential candidate Hillary Clinton, interviewed the Geico Gecko in April 2013. He had since became GEICO's longest-running mascot, appearing in more than 150 commercials as of 2017.

Student A:Aqueducts moved water through gravity alone, along a slight overall downward gradient within conduits of stone, brick, or concrete; the steeper the gradient, the faster the flow. Most conduits were buried beneath the ground and followed the contours of the terrain; obstructing peaks were circumvented or, less often, tunneled through. Where valleys or lowlands intervened, the conduit was carried on bridgework, or its contents fed into high-pressure lead, ceramic, or stone pipes and siphoned across. Most aqueduct systems included sedimentation tanks, which helped reduce any water-borne debris. Sluices and castella aquae (distribution tanks) regulated the supply to individual destinations. In cities and towns, the run-off water from aqueducts scoured the drains and sewers.
