Problem: Alps:

The altitude and size of the range affects the climate in Europe; in the mountains precipitation levels vary greatly and climatic conditions consist of distinct zones. Wildlife such as ibex live in the higher peaks to elevations of 3,400 m (11,155 ft), and plants such as Edelweiss grow in rocky areas in lower elevations as well as in higher elevations. Evidence of human habitation in the Alps goes back to the Paleolithic era.

What plant grows in the rocky areas of the range?
---
A: Edelweiss

Problem: The emergence of resistance of bacteria to antibiotics is a common phenomenon. Emergence of resistance often reflects evolutionary processes that take place during antibiotic therapy. The antibiotic treatment may select for bacterial strains with physiologically or genetically enhanced capacity to survive high doses of antibiotics. Under certain conditions, it may result in preferential growth of resistant bacteria, while growth of susceptible bacteria is inhibited by the drug. For example, antibacterial selection for strains having previously acquired antibacterial-resistance genes was demonstrated in 1943 by the LuriaDelbruck experiment. Antibiotics such as penicillin and erythromycin, which used to have a high efficacy against many bacterial species and strains, have become less effective, due to the increased resistance of many bacterial strains.
What is the purpose of bacterial strains?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
One wave of the population boom ended abruptly in the mid-1980s, as oil prices fell precipitously. The space industry also suffered in 1986 after the Space Shuttle Challenger disintegrated shortly after launch. There was a cutback in some activities for a period. In the late 1980s, the city's economy suffered from the nationwide recession. After the early 1990s recession, Houston made efforts to diversify its economy by focusing on aerospace and health care/biotechnology, and reduced its dependence on the petroleum industry. Since the increase of oil prices in the 2000s, the petroleum industry has again increased its share of the local economy.
The petroleum industry did not become a larger part of Houston's economy again for what reason?
A: unanswerable

Context and question: Compass-M1 transmits in 3 bands: E2, E5B, and E6. In each frequency band two coherent sub-signals have been detected with a phase shift of 90 degrees (in quadrature). These signal components are further referred to as "I" and "Q". The "I" components have shorter codes and are likely to be intended for the open service. The "Q" components have much longer codes, are more interference resistive, and are probably intended for the restricted service. IQ modulation has been the method in both wired and wireless digital modulation since morsetting carrier signal 100 years ago.
How many coherent sub-signals have been detected in each orbit?
Answer: unanswerable

Question: Today, this term also refers to the doctrines and practices of the Reformed churches of which Calvin was an early leader. Less commonly, it can refer to the individual teaching of Calvin himself. The particulars of Calvinist theology may be stated in a number of ways. Perhaps the best known summary is contained in the five points of Calvinism, though these points identify the Calvinist view on soteriology rather than summarizing the system as a whole. Broadly speaking, Calvinism stresses the sovereignty or rule of God in all things in salvation but also in all of life. This concept is seen clearly in the doctrines of predestination and total depravity.
Is there an answer to this question: What Calvinism doctrines are examples of the concept of the sovereignty of God?

Answer: predestination and total depravity

Problem: Bras%C3%ADlia:

The Cathedral of Brasilia in the capital of the Federative Republic of Brazil, is an expression of the architect Oscar Niemeyer. This concrete-framed hyperboloid structure, seems with its glass roof reaching up, open, to the heavens. On 31 May 1970, the Cathedral's structure was finished, and only the 70 m (229.66 ft) diameter of the circular area were visible. Niemeyer's project of Cathedral of Brasilia is based in the hyperboloid of revolution which sections are asymmetric. The hyperboloid structure itself is a result of 16 identical assembled concrete columns. These columns, having hyperbolic section and weighing 90 t, represent two hands moving upwards to heaven. The Cathedral was dedicated on 31 May 1970.

How much does the glass weigh?

A:
unanswerable
