Question: How old was Reg Smith the year he capped twice and scored 2 goals for England? Passage:In the 192526 season Millwall had 11 consecutive clean sheets, a Football League record, which they hold jointly with York City and Reading. Millwall became known as a hard-fighting Cup team and competed in various memorable matches, notably defeating three-time league winners and reigning champions Huddersfield Town 31 in the third round of the 192627 FA Cup. In the 192728 season Millwall won the Third Division South title and scored 87 goals at home in the league, an English record which still stands. Matches against Sunderland and Derby County saw packed crowds of 48,000-plus in the 1930s and 1940s. Their 1937 FA Cup run saw Millwall reach the semi-finals for the third time, and a fifth-round game against Derby still stands as Millwall's record attendance of 48,762. Millwall were the 11th best supported team in England in 1939, despite being in the Second Division. Millwall were one of the most financially wealthy clubs in England. The club proposed plans to improve the Den and signed international players. Winger Reg 'JR' Smith was capped twice, scoring two goals for England in 1938. The Lions were pushing for promotion to the First Division toward the end of the decade, but one week into the 193940 season, World War II broke out and Millwall were robbed of their aim.

Question: Who was the oldest among those players who tied for second highest scorer in FIFA World Cup qualifying?

Question: How old was Robert Guiscard when he defeated the papal troops of Pope Leo IX? Passage:San Severo lies on the Daunia, and various Neolithic settlements have been detected. In the early Middle Ages, the area was not inhabited or defined. Between the Lombards and the Byzantine ages, the Benedictine monastery at Cassino was established, and with it, the cult of the apostle of Saint Severinus of Noricum. San Severo was founded in the 11th century around a small church built by the Benedictine monks from Montecassino. It rapidly developed as a trade town. In 1053, it was the scene of the historical victory of Robert Guiscard over the papal troops under Pope Leo IX (see Battle of Civitate). In the eleventh century, San Severo was the route of the Via Sacra Langobardorum and a primitive church arose dedicated to Saint Severino, from which continued an influx of pilgrims to Monte Sant'Angelo and movement of people and goods. The town was therefore called Castellum Sancti Severini ("Fortified Town of San Severo").
