Question: 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.
Try to answer this question if possible: What ingredients give glass-ceramics its useful heat tolerance?
Answer: lithium and aluminosilicates
Question: Since the 1988 Education Reform Act, parents have a right to choose which school their child should go to or whether to not send them to school at all and to home educate them instead. The concept of "school choice" introduces the idea of competition between state schools, a fundamental change to the original "neighbourhood comprehensive" model, and is partly intended as a means by which schools that are perceived to be inferior are forced either to improve or, if hardly anyone wants to go there, to close down. Government policy is currently promoting 'specialisation' whereby parents choose a secondary school appropriate for their child's interests and skills. Most initiatives focus on parental choice and information, implementing a pseudo-market incentive to encourage better schools. This logic has underpinned the controversial league tables of school performance.

Answer: unanswerable
Question: In July 2013 Tuvalu signed the Memorandum of Understanding (MOU) to establish the Pacific Regional Trade and Development Facility, which Facility originated in 2006, in the context of negotiations for an Economic Partnership Agreement (EPA) between Pacific ACP States and the European Union. The rationale for the creation of the Facility being to improve the delivery of aid to Pacific island countries in support of the Aid-for-Trade (AfT) requirements. The Pacific ACP States are the countries in the Pacific that are signatories to the Cotonou Agreement with the European Union.
Try to answer this question if possible: What trade agreement did Tuvalu sign in 2013?
Answer: Memorandum of Understanding
Question: With Zaifeng gone, Yuan Shikai and his Beiyang commanders effectively dominated Qing politics. He reasoned that going to war would be unreasonable and costly, especially when noting that the Qing government had a goal for constitutional monarchy. Similarly, Sun Yat-sen's government wanted a republican constitutional reform, both aiming for the benefit of China's economy and populace. With permission from Empress Dowager Longyu, Yuan Shikai began negotiating with Sun Yat-sen, who decided that his goal had been achieved in forming a republic, and that therefore he could allow Yuan to step into the position of President of the Republic of China.
Try to answer this question if possible: Who became the President?
Answer:
Yuan
