question:
Passage: Glass remained a luxury material, and the disasters that overtook Late Bronze Age civilizations seem to have brought glass-making to a halt. Indigenous development of glass technology in South Asia may have begun in 1730 BCE. In ancient China, though, glassmaking seems to have a late start, compared to ceramics and metal work. The term glass developed in the late Roman Empire. It was in the Roman glassmaking center at Trier, now in modern Germany, that the late-Latin term glesum originated, probably from a Germanic word for a transparent, lustrous substance. Glass objects have been recovered across the Roman empire in domestic, industrial and funerary contexts.[citation needed] Question: In what year did glassmaking begin in Asia?
answer:
1730 BCE


question:
Passage: In the mid-1950s, Frank Burnet, inspired by a suggestion made by Niels Jerne, formulated the clonal selection theory (CST) of immunity. On the basis of CST, Burnet developed a theory of how an immune response is triggered according to the self/nonself distinction: "self" constituents (constituents of the body) do not trigger destructive immune responses, while "nonself" entities (e.g., pathogens, an allograft) trigger a destructive immune response. The theory was later modified to reflect new discoveries regarding histocompatibility or the complex "two-signal" activation of T cells. The self/nonself theory of immunity and the self/nonself vocabulary have been criticized, but remain very influential. Question: What property of T cells caused modification of CST?
answer:
the complex "two-signal" activation


question:
Passage: From the middle of the 18th century, exploration and publication changed the course of British architecture towards a purer vision of the Ancient Greco-Roman ideal. James 'Athenian' Stuart's work The Antiquities of Athens and Other Monuments of Greece was very influential in this regard, as were Robert Wood's Palmyra and Baalbec. A combination of simple forms and high levels of enrichment was adopted by the majority of contemporary British architects and designers. The revolution begun by Stuart was soon to be eclipsed by the work of the Adam Brothers, James Wyatt, Sir William Chambers, George Dance, James Gandon and provincially based architects such as John Carr and Thomas Harrison of Chester. Question: What direction did British architecture go in mid 18th century?
answer:

Ancient Greco-Roman ideal
