Input: Article: The first elevator shaft preceded the first elevator by four years. Construction for Peter Cooper's Cooper Union Foundation building in New York began in 1853. An elevator shaft was included in the design, because Cooper was confident that a safe passenger elevator would soon be invented. The shaft was cylindrical because Cooper thought it was the most efficient design. Later, Otis designed a special elevator for the building. Today the Otis Elevator Company, now a subsidiary of United Technologies Corporation, is the world's largest manufacturer of vertical transport systems.

Now answer this question: What title does United Technologies Corporation hold?

Output: world's largest manufacturer of vertical transport systems

Article: Another solution to the problem of causality-based temporal paradoxes is that such paradoxes cannot arise simply because they have not arisen. As illustrated in numerous works of fiction, free will either ceases to exist in the past or the outcomes of such decisions are predetermined. As such, it would not be possible to enact the grandfather paradox because it is a historical fact that your grandfather was not killed before his child (your parent) was conceived. This view doesn't simply hold that history is an unchangeable constant, but that any change made by a hypothetical future time traveler would already have happened in his or her past, resulting in the reality that the traveler moves from. More elaboration on this view can be found in the Novikov self-consistency principle.

Question: In several works of fiction, what ceases to exist in the past which causes paradoxes not to arise?
Ans: free will

Here is a question about this article: In 1963, the Robbins Report on universities in the United Kingdom concluded that such institutions should have four main "objectives essential to any properly balanced system: instruction in skills; the promotion of the general powers of the mind so as to produce not mere specialists but rather cultivated men and women; to maintain research in balance with teaching, since teaching should not be separated from the advancement of learning and the search for truth; and to transmit a common culture and common standards of citizenship."
What is the answer to this question: The Robbins Report says universities should transmit what?
****
So... a common culture and common standards of citizenship

The problem: Answer a question about this article:
However, the classification of madaris as "universities" is disputed on the question of understanding of each institution on its own terms. In madaris, the ijazahs were only issued in one field, the Islamic religious law of shariah, and in no other field of learning. Other academic subjects, including the natural sciences, philosophy and literary studies, were only treated "ancillary" to the study of the Sharia. For example, a natural science like astronomy was only studied (if at all) to supply religious needs, like the time for prayer. This is why Ptolemaic astronomy was considered adequate, and is still taught in some modern day madaris. The Islamic law undergraduate degree from al-Azhar, the most prestigious madrasa, was traditionally granted without final examinations, but on the basis of the students' attentive attendance to courses. In contrast to the medieval doctorate which was granted by the collective authority of the faculty, the Islamic degree was not granted by the teacher to the pupil based on any formal criteria, but remained a "personal matter, the sole prerogative of the person bestowing it; no one could force him to give one".
Who decided if a student earned a law degree in undergraduate madaris?
****
The answer: the teacher

Problem: Please answer a question about the following article about Capacitor:
Several other types of capacitor are available for specialist applications. Supercapacitors store large amounts of energy. Supercapacitors made from carbon aerogel, carbon nanotubes, or highly porous electrode materials, offer extremely high capacitance (up to 5 kF as of 2010[update]) and can be used in some applications instead of rechargeable batteries. Alternating current capacitors are specifically designed to work on line (mains) voltage AC power circuits. They are commonly used in electric motor circuits and are often designed to handle large currents, so they tend to be physically large. They are usually ruggedly packaged, often in metal cases that can be easily grounded/earthed. They also are designed with direct current breakdown voltages of at least five times the maximum AC voltage.
What type of capacitor is commonly used in electric motor circuits?
A: Alternating current capacitors

Question: Read this and answer the question

Following the start of the Arab Spring in 2011, Gaddafi spoke out in favour of Tunisian President Zine El Abidine Ben Ali, then threatened by the Tunisian Revolution. He suggested that Tunisia's people would be satisfied if Ben Ali introduced a Jamahiriyah system there. Fearing domestic protest, Libya's government implemented preventative measures, reducing food prices, purging the army leadership of potential defectors and releasing several Islamist prisoners. They proved ineffective, and on 17 February 2011, major protests broke out against Gaddafi's government. Unlike Tunisia or Egypt, Libya was largely religiously homogenous and had no strong Islamist movement, but there was widespread dissatisfaction with the corruption and entrenched systems of patronage, while unemployment had reached around 30%.

About what percentage of the Libyan population was unemployed in 2011?
Answer:
30
