[EX Q]: Passage: The V&A has its origins in the Great Exhibition of 1851, with which Henry Cole, the museum's first director, was involved in planning; initially it was known as the Museum of Manufactures, first opening in May 1852 at Marlborough House, but by September had been transferred to Somerset House. At this stage the collections covered both applied art and science. Several of the exhibits from the Exhibition were purchased to form the nucleus of the collection. By February 1854 discussions were underway to transfer the museum to the current site and it was renamed South Kensington Museum. In 1855 the German architect Gottfried Semper, at the request of Cole, produced a design for the museum, but it was rejected by the Board of Trade as too expensive. The site was occupied by Brompton Park House; this was extended including the first refreshment rooms opened in 1857, the museum being the first in the world to provide such a facility. Question: Which German architect was asked to produce a design for the museum?
[EX A]: Gottfried Semper

[EX Q]: Passage: DECnet is a suite of network protocols created by Digital Equipment Corporation, originally released in 1975 in order to connect two PDP-11 minicomputers. It evolved into one of the first peer-to-peer network architectures, thus transforming DEC into a networking powerhouse in the 1980s. Initially built with three layers, it later (1982) evolved into a seven-layer OSI-compliant networking protocol. The DECnet protocols were designed entirely by Digital Equipment Corporation. However, DECnet Phase II (and later) were open standards with published specifications, and several implementations were developed outside DEC, including one for Linux. Question: What is  DECnet
[EX A]: a suite of network protocols created by Digital Equipment Corporation
