Problem: 2008 Sichuan earthquake:

On May 12, 2009, China marked the first anniversary of the quake with a moment of silence as people across the nation remembered the dead. The government also opened access to the sealed ruins of the Beichuan county seat for three days, after which it will be frozen in time as a state earthquake relic museum, to remind people of the terrible disaster. There were also several concerts across the country to raise money for the survivors of the quake.

What will the Beichuan county seat be used for?
---
A: earthquake relic museum

Problem: Idealism:

Subjective idealists like George Berkeley are anti-realists in terms of a mind-independent world, whereas transcendental idealists like Immanuel Kant are strong skeptics of such a world, affirming epistemological and not metaphysical idealism. Thus Kant defines idealism as "the assertion that we can never be certain whether all of our putative outer experience is not mere imagining". He claimed that, according to idealism, "the reality of external objects does not admit of strict proof. On the contrary, however, the reality of the object of our internal sense (of myself and state) is clear immediately through consciousness." However, not all idealists restrict the real or the knowable to our immediate subjective experience. Objective idealists make claims about a transempirical world, but simply deny that this world is essentially divorced from or ontologically prior to the mental. Thus Plato and Gottfried Leibniz affirm an objective and knowable reality transcending our subjective awarenessa rejection of epistemological idealismbut propose that this reality is grounded in ideal entities, a form of metaphysical idealism. Nor do all metaphysical idealists agree on the nature of the ideal; for Plato, the fundamental entities were non-mental abstract forms, while for Leibniz they were proto-mental and concrete monads.

What famous philosopher was a transcendental idealist?

A: Immanuel Kant

Problem: Light-emitting diode:

Recent developments in LEDs permit them to be used in environmental and task lighting. LEDs have many advantages over incandescent light sources including lower energy consumption, longer lifetime, improved physical robustness, smaller size, and faster switching. Light-emitting diodes are now used in applications as diverse as aviation lighting, automotive headlamps, advertising, general lighting, traffic signals, camera flashes and lighted wallpaper. As of 2015[update], LEDs powerful enough for room lighting remain somewhat more expensive, and require more precise current and heat management, than compact fluorescent lamp sources of comparable output.

What is a popular use for non-LED lighting?
---
A: unanswerable

Problem: University:

An important idea in the definition of a university is the notion of academic freedom. The first documentary evidence of this comes from early in the life of the first university. The University of Bologna adopted an academic charter, the Constitutio Habita, in 1158 or 1155, which guaranteed the right of a traveling scholar to unhindered passage in the interests of education. Today this is claimed as the origin of "academic freedom". This is now widely recognised internationally - on 18 September 1988, 430 university rectors signed the Magna Charta Universitatum, marking the 900th anniversary of Bologna's foundation. The number of universities signing the Magna Charta Universitatum continues to grow, drawing from all parts of the world.

What charter is said to be the first establishing education in a university?

A:
unanswerable
