Question: Which play was published first? Passage 1:In 1980, Conroy decided to try his hand in television and moved out to California. He landed a role in the daytime soap opera Another World. Conroy became associated with the Old Globe Theatre in San Diego, California, where he performed in productions of Hamlet and A Midsummer Night's Dream. From 1980 to 1985, he acted in a variety of contemporary and classic theatre pieces, including the Broadway productions of Eastern Standard and Edward Albee's adaptation of Lolita. In 1984, Conroy played the title role in Hamlet at the New York Shakespeare Festival. He returned to television in the 1985 TV movie Covenant and had a role on another daytime soap drama, Search for Tomorrow. Conroy played gay lawyer Bart Fallmont on Dynasty from 1985 to 1986. He was a series regular on Ohara in 1987, and as the company commander on Tour of Duty from 1987 to 1988, before starring in a series of television movies. Though initially cast as one of the show's main characters, his role on the show was reduced while it filmed in Hawaii and he ended up spending much of his time doing portraits of tourists on the Honolulu boardwalk. Conroy has also guest starred on shows such as Cheers, Search for Tomorrow, Matlock and Murphy Brown.
 Passage 2:After their defeat at the Battle of Walaja, the Sassanid survivors of the battle who consisted mostly of Christian Arabs fled from the battlefield, crossed the River Khaseef (a tributary of the Euphrates) and moved between it and the Euphrates. Their flight ended at Ullais, about 10 miles from the location of the Battle of Walaja. The Muslims were aware of the presence of hostile Arabs at Ullais but, as they were less numerous and were survivors of Walaja, they never considered them a military threat until they started to regroup and the Muslim commander Khalid ibn Walid was informed about the arrival of more Arab hordes, mainly from the Christian Arab tribe of Bani Bakr. More reinforcements were raised from the Christian Arab tribes in the region between Al-Hirah and Ullais. The Rashidun Caliphate army under Khalid crossed the river Khaseef and approached Ullais frontally. Emperor Ardsheer meanwhile sent orders to Bahman Jaduya to proceed to Ullais and take command of Arab contingents there and stop the Muslims advance at Ullais. Bahman sent his senior general Jaban with the imperial army to Ullais with orders to avoid battle until Bahman Jaduya himself arrived. As Jaban set off with the army, Bahman Jaduya returned to Ctesiphon to discuss certain matters with the Emperor. He arrived at Ctesiphon to find Emperor Ardsheer very ill and remained in attendance on him. By now the Persians and Arabs had realised that the Muslims' objective was Al-Hirah. They decided to fight and defeat the Muslims army. The Christian Arab contingents were under the command of a tribal chief called Abdul-Aswad, who had lost his two sons in the Battle of Walaja against the Muslims and wanted revenge.
 Passage 3:Mulgrew Nunatak () is a prominent nunatak, 1,600 m, standing four nautical miles (7 km) east of Tentacle Ridge in the Cook Mountains. Its summit, standing at , is named Peter Crest. The nunatak was first mapped by the Darwin Glacier Party of the Commonwealth Trans-Antarctic Expedition (1956–58). Both it and its peak were named for Peter D. Mulgrew, a New Zealand adventurer who accompanied Sir Edmund Hillary to the South Pole and served as the chief radio operator at Scott Base. He perished in the Air New Zealand DC10 scenic flight to Ross Island, 28 November 1979, when the airplane crashed near Te Puna Roimata Peak ("spring of tears" peak) on the northeast slope of Mount Erebus, killing all 257 persons aboard.
