Problem: Constantius, ordered Liberius into exile in 356 giving him, then, three days to comply. He was ordered into banishment to Beroea, in Thrace; Beroea (Thrace). He sent expensive presents, too, if he were to accept the Arian position but were refused. He sent him, indeed, five hundred pieces of gold "to bear his charges" but Liberius refused them, saying, he might bestow them on his flatters; as he did also a like present from the empress, bidding the messenger learn to believe in Christ, and not to persecute the Church of God. Attempts were made to leave the presents in The Church, but Liberius threw them out. Constantius hereupon sent for him under a strict guard to Milan, where, in a conference recorded by Theodoret, he boldly told Constantius that Athanasius had been acquitted at Sardica, and his enemies proved calumniators (see: "calumny") and impostors, and that it was unjust to condemn a person who could not be legally convicted of any crime. The emperor was reduced to silence on every article, but being the more out of patience, ordered him into banishment. Liberius went into exile. Constantius, after two years went to Rome to celebrate the twentieth year of his reign. The ladies joined in a petition to him that he would restore Liberius. He assented, upon condition that he should comply with the bishops, then, at court. He subscribed the condemnation of Athanasius, and a confession or creed which had been framed by the Arians at Sirmium. And he no sooner had recovered his see that he declared himself for the Creed of Niceae, as Theodoret testifies. (Theodoret, Hist. lib. ii. c. 17.). The Emperor knew what he wanted people to believe.

In the early part of the 20th century, San Diego hosted two World's Fairs: the Panama-California Exposition in 1915 and the California Pacific International Exposition in 1935. Both expositions were held in Balboa Park, and many of the Spanish/Baroque-style buildings that were built for those expositions remain to this day as central features of the park. The buildings were intended to be temporary structures, but most remained in continuous use until they progressively fell into disrepair. Most were eventually rebuilt, using castings of the original facades to retain the architectural style. The menagerie of exotic animals featured at the 1915 exposition provided the basis for the San Diego Zoo. During the 1950s there was a citywide festival called Fiesta del Pacifico highlighting the area's Spanish and Mexican past. In the 2010s there was a proposal for a large-scale celebration of the 100th anniversary of Balboa Park, but the plans were abandoned when the organization tasked with putting on the celebration went out of business.
What park in San Diego hosted two World Fairs near the beginning of the 19th century?
A: unanswerable

Context and question: As the 1954 congressional elections approached, and it became evident that the Republicans were in danger of losing their thin majority in both houses, Eisenhower was among those blaming the Old Guard for the losses, and took up the charge to stop suspected efforts by the right wing to take control of the GOP.
