Question: Which stadium Cross played in holds more fans, Vale Park or Belle Vue? Passage:Cross began his career at Walsall, who finished 12th in the Third Division in 196667 under the stewardship of Ray Shaw. New boss Ron Lewin then took the "Saddlers" to a seventh-place finish in 196768. After a 13th-place finish in 196869, Bill Moore returned to lead Walsall to 12th place in 196970. Cross played just 12 league games in his four years at Fellows Park. He joined Gordon Lee's Port Vale in July 1970. He made his debut on 5 September, in a 10 win over Preston North End at Vale Park. He played 42 Third Division games in the 197071 season, and scored his first goal in the Football League on 2 January, in a 21 win over Doncaster Rovers at Belle Vue. He was an ever-present in the 197172 season, playing all 46 league and five cup games. He made 40 appearances in the 197273 season, and ended a series of 134 consecutive appearances from his debut in March 1973 when he wrenched his left knee. He recovered from this injury to play just two games in the 197374 campaign, but then he injured his knee ligaments in October 1973 and was out of action for 17 months. He managed to play just two games in the 197475 season, and was handed a free transfer in May 1975 by new manager Roy Sproson. He went on to play for Southern League side Nuneaton Borough. Upon his retirement as a player, he became a School of Excellence coach at Stoke City. He later went on to become a teacher for 25 years.

Question: Where is the entity located that the two Phillies pitchers were inducted into? Passage:Of those Phillies, 97 have had surnames beginning with the letter R. Two of those players have been inducted into the Baseball Hall of Fame: pitcher Eppa Rixey, who was a Phillie for six seasons in two different stints (19121917, 1919); and Robin Roberts, who won 20 games during the 1950 season as the ace pitcher of the Whiz Kids. The Hall of Fame lists the Phillies as Roberts' primary team; during his career, the right-hander won 234 games and lost 199, the latter one of his three franchise records. During his 14 seasons with the team, he pitched 3,739 innings and completed 272 games, both records; he also held the major league record for most career home runs allowed until it was broken in 2010. Roberts was also elected to the Philadelphia Baseball Wall of Fame as the Phillies' first inductee in 1978.

Question: In which way did the legate enforce clerical celibacy? Passage:The first Archbishop of Uppsala was Stephen, a Cistercian monk from the celebrated Alvastra Abbey. Cardinal William of Sabina came as papal legate to Sweden during the archiepiscopate of Jarler, a Dominican friar (123555). The legate had been commissioned, among other things, to establish cathedral chapters wherever such were lacking, and to grant them the exclusive right of electing the bishops. Another important matter which the legate had been ordered to carry out was the enforcement of the law of clerical celibacy. At a provincial synod held at Skanninge in 1248 under the presidency of the cardinal, the rules as to celibacy were made more severe. The pious and energetic Archbishop Jarler and his successor Laurentius (125767), a Franciscan, constantly strove to elevate the clergy and to enforce the law of celibacy. A century later Saint Bridget (d. 1373), laboured zealously for the enforcement of the same law.
