[EX Q]: Richard Nixon used national security as a basis for his expansion of power. He asserted, for example, that "the inherent power of the President to safeguard the security of the nation" authorized him to order a wiretap without a judge's warrant. Nixon also asserted that "executive privilege" shielded him from all legislative oversight; furthermore, he impounded federal funds (that is to say, he refused to spend money that Congress had appropriated for government programs). In the specific cases aforementioned, however, the Supreme Court ruled against Nixon. This was also because of an ongoing criminal investigation into the Watergate tapes, even though they acknowledged the general need for executive privilege. Since then, Nixon's successors have sometimes asserted that they may act in the interests of national security or that executive privilege shields them from Congressional oversight. Though such claims have in general been more limited than Nixon's, one may still conclude that the presidency's power has been greatly augmented since the eighteenth and nineteenth centuries.
[EX A]: Under what basis did Richard Nixon assert an expansion of the power of the President?

[EX Q]: The double indirect method can be used when it is important to see the work during the creation process as it will appear when completed. The tesserae are placed face-up on a medium (often adhesive-backed paper, sticky plastic or soft lime or putty) as it will appear when installed. When the mosaic is complete, a similar medium is placed atop it. The piece is then turned over, the original underlying material is carefully removed, and the piece is installed as in the indirect method described above. In comparison to the indirect method, this is a complex system to use and requires great skill on the part of the operator, to avoid damaging the work. Its greatest advantage lies in the possibility of the operator directly controlling the final result of the work, which is important e.g. when the human figure is involved. This method was created in 1989 by Maurizio Placuzzi and registered for industrial use (patent n. 0000222556) under the name of his company, Sicis International Srl, now Sicis The Art Mosaic Factory Srl.
[EX A]: When is the double indirect method of mosaic useful?

[EX Q]: John grew up to be around 5 ft 5 in (1.68 m) tall, relatively short, with a "powerful, barrel-chested body" and dark red hair; he looked to contemporaries like an inhabitant of Poitou. John enjoyed reading and, unusually for the period, built up a travelling library of books. He enjoyed gambling, in particular at backgammon, and was an enthusiastic hunter, even by medieval standards. He liked music, although not songs. John would become a "connoisseur of jewels", building up a large collection, and became famous for his opulent clothes and also, according to French chroniclers, for his fondness for bad wine. As John grew up, he became known for sometimes being "genial, witty, generous and hospitable"; at other moments, he could be jealous, over-sensitive and prone to fits of rage, "biting and gnawing his fingers" in anger.[nb 3]
[EX A]:
How tall was John?
