[Q]: Given the following passage  "In the First World War, Devonport was the headquarters of Western Approaches Command until 1941 and Sunderland flying boats were operated by the Royal Australian Air Force. It was an important embarkation point for US troops for D-Day. The city was heavily bombed by the Luftwaffe, in a series of 59 raids known as the Plymouth Blitz. Although the dockyards were the principal targets, much of the city centre and over 3,700 houses were completely destroyed and more than 1,000 civilians lost their lives. This was largely due to Plymouth's status as a major port Charles Church was hit by incendiary bombs and partially destroyed in 1941 during the Blitz, but has not been demolished, as it is now an official permanent monument to the bombing of Plymouth during World War II.",  answer the following question.

[Q]: Given the following passage  "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 the following question. Note that the answer is present within the text.  Question: What is an example of something that is not a precipitation hardening alloy?
****
[A]: steel


[Q]: Given the following passage  "Instruments were marketed by teacher-dealers, much as the title character in the popular musical The Music Man. Often, these teacher-dealers conducted mandolin orchestras: groups of 4-50 musicians who played various mandolin family instruments. However, alongside the teacher-dealers were serious musicians, working to create a spot for the instrument in classical music, ragtime and jazz. Like the teacher-dealers, they traveled the U.S., recording records, giving performances and teaching individuals and mandolin orchestras. Samuel Siegel played mandolin in Vaudeville and became one of America's preeminent mandolinists. Seth Weeks was an African American who not only taught and performed in the United States, but also in Europe, where he recorded records. Another pioneering African American musician and director who made his start with a mandolin orchestra was composer James Reese Europe. W. Eugene Page toured the country with a group, and was well known for his mandolin and mandola performances. Other names include Valentine Abt, Samuel Adelstein, William Place, Jr., and Aubrey Stauffer.",  answer the following question. Note that the answer is present within the text.  Question: What subject showed a little of what mandolin players do?
****
[A]: The Music Man


[Q]: Given the following passage  "Although Mali has enjoyed a reasonably good inter-ethnic relationships based on the long history of coexistence, some hereditary servitude and bondage relationship exist, as well as ethnic tension between settled Songhai and nomadic Tuaregs of the north. Due to a backlash against the northern population after independence, Mali is now in a situation where both groups complain about discrimination on the part of the other group. This conflict also plays a role in the continuing Northern Mali conflict where there is a tension between both Tuaregs and the Malian government, and the Tuaregs and radical Islamists who are trying to establish sharia law.",  answer the following question. Note that the answer is present within the text.  Question: How do we know that life in Mali could be better?
