Problem: Question: "What is an example of something that is not a precipitation hardening alloy?" Context: "Conversely, most heat-treatable alloys are precipitation hardening alloys, which produce the opposite effects that steel does. When heated to form a solution and then cooled quickly, these alloys become much softer than normal, during the diffusionless transformation, and then harden as they age. The solutes in these alloys will precipitate over time, forming intermetallic phases, which are difficult to discern from the base metal. Unlike steel, in which the solid solution separates to form different crystal phases, precipitation hardening alloys separate to form different phases within the same crystal. These intermetallic alloys appear homogeneous in crystal structure, but tend to behave heterogeneous, becoming hard and somewhat brittle." Answer:

A: steel

Problem: Question: "Which of the following is not a Libyan revolutionary group: Black Boots, the Central Intelligence Agency, or the Free Officers Movement?" Context: "Idris' government was increasingly unpopular by the latter 1960s; it had exacerbated Libya's traditional regional and tribal divisions by centralising the country's federal system in order to take advantage of the country's oil wealth, while corruption and entrenched systems of patronage were widespread throughout the oil industry. Arab nationalism was increasingly popular, and protests flared up following Egypt's 1967 defeat in the Six-Day War with Israel; allied to the western powers, Idris' administration was seen as pro-Israeli. Anti-western riots broke out in Tripoli and Benghazi, while Libyan workers shut down oil terminals in solidarity with Egypt. By 1969, the U.S. Central Intelligence Agency was expecting segments of Libya's armed forces to launch a coup. Although claims have been made that they knew of Gaddafi's Free Officers Movement, they have since claimed ignorance, stating that they were monitoring Abdul Aziz Shalhi's Black Boots revolutionary group." Answer:

A: Central Intelligence Agency
