(ii) create questions which require information beyond what is provided in the passage in order to answer
(iii) replace an existing entity, number, date mentioned in the passage with other entity, number, date and use it in the question

[EX Q]: Passage: The PLP, the party in government when the decision to join CARICOM was made, has been dominated for decades by West Indians and their descendants. (The prominent roles of West Indians among Bermuda's black politicians and labour activists predated party politics in Bermuda, as exemplified by Dr. E. F. Gordon). The late PLP leader, Dame Lois Browne-Evans, and her Trinidadian-born husband, John Evans (who co-founded the West Indian Association of Bermuda in 1976), were prominent members of this group. They have emphasised Bermuda's cultural connections with the West Indies. Many Bermudians, both black and white, who lack family connections to the West Indies have objected to this emphasis.
[EX A]: Who had dominated CARICOM?

[EX Q]: Passage: There are fifteen fraternities and seven sororities at the University of Chicago, as well as one co-ed community service fraternity, Alpha Phi Omega.

[EX Q]: Passage: Soon after the passing of the 1931 Act, in the book published on the occasion of the Institute's centenary celebration in 1934, Harry Barnes, FRIBA, Chairman of the Registration Committee, mentioned that ARCUK could not be a rival of any architectural association, least of all the RIBA, given the way ARCUK was constituted. Barnes commented that the Act's purpose was not protecting the architectural profession, and that the legitimate interests of the profession were best served by the (then) architectural associations in which some 80 per cent of those practising architecture were to be found.
[EX A]:
