Problem: Queen Victoria:

Victoria was pleased when Gladstone resigned in 1885 after his budget was defeated. She thought his government was "the worst I have ever had", and blamed him for the death of General Gordon at Khartoum. Gladstone was replaced by Lord Salisbury. Salisbury's government only lasted a few months, however, and Victoria was forced to recall Gladstone, whom she referred to as a "half crazy & really in many ways ridiculous old man". Gladstone attempted to pass a bill granting Ireland home rule, but to Victoria's glee it was defeated. In the ensuing election, Gladstone's party lost to Salisbury's and the government switched hands again.

Who replaced Gladstone after he was fired?

Problem: Affirmative action in the United States:

In the year 2000, according to a study by American Association of University Professors (AAUP), affirmative action promoted diversity within colleges and universities. This has been shown to have positive effects on the educational outcomes and experiences of college students as well as the teaching of faculty members. According to a study by Geoffrey Maruyama and Jose F. Moreno, the results showed that faculty members believed diversity helps students to reach the essential goals of a college education, Caucasian students suffer no detrimental effects from classroom diversity, and that attention to multicultural learning improves the ability of colleges and universities to accomplish their missions. Furthermore, a diverse population of students offers unique perspectives in order to challenge preconceived notions through exposure to the experiences and ideas of others. According to Professor Gurin of the University of Michigan, skills such as "perspective-taking, acceptance of differences, a willingness and capacity to find commonalities among differences, acceptance of conflict as normal, conflict resolution, participation in democracy, and interest in the wider social world" can potentially be developed in college while being exposed to heterogeneous group of students. In addition, broadening perspectives helps students confront personal and substantive stereotypes and fosters discussion about racial and ethnic issues in a classroom setting. Furthermore, the 2000 AAUP study states that having a diversity of views leads to a better discussion and greater understanding among the students on issues of race, tolerance, fairness, etc.

In which year did the AAUP release their study?

A: 2000

Problem: Frederic Chopin:

In June 1837 Chopin visited London incognito in the company of the piano manufacturer Camille Pleyel where he played at a musical soiree at the house of English piano maker James Broadwood. On his return to Paris, his association with Sand began in earnest, and by the end of June 1838 they had become lovers. Sand, who was six years older than the composer, and who had had a series of lovers, wrote at this time: "I must say I was confused and amazed at the effect this little creature had on me ... I have still not recovered from my astonishment, and if I were a proud person I should be feeling humiliated at having been carried away ..." The two spent a miserable winter on Majorca (8 November 1838 to 13 February 1839), where, together with Sand's two children, they had journeyed in the hope of improving the health of Chopin and that of Sand's 15-year-old son Maurice, and also to escape the threats of Sand's former lover Felicien Mallefille. After discovering that the couple were not married, the deeply traditional Catholic people of Majorca became inhospitable, making accommodation difficult to find. This compelled the group to take lodgings in a former Carthusian monastery in Valldemossa, which gave little shelter from the cold winter weather.

Problem: Glass:

The term mainly refers to a mix of lithium and aluminosilicates that yields an array of materials with interesting thermomechanical properties. The most commercially important of these have the distinction of being impervious to thermal shock. Thus, glass-ceramics have become extremely useful for countertop cooking. The negative thermal expansion coefficient (CTE) of the crystalline ceramic phase can be balanced with the positive CTE of the glassy phase. At a certain point (~70% crystalline) the glass-ceramic has a net CTE near zero. This type of glass-ceramic exhibits excellent mechanical properties and can sustain repeated and quick temperature changes up to 1000 C.

What proportion of crystalline ceramics yields a product with a CTE of around 0?

A:
~70%
