Problem: Spectre (2015 film):

Filming temporarily returned to England to shoot scenes at Blenheim Palace in Oxfordshire, which stood in for a location in Rome, before moving on to the city itself for a five-week shoot across the city, with locations including the Ponte Sisto bridge and the Roman Forum. The production faced opposition from a variety of special interest groups and city authorities, who were concerned about the potential for damage to historical sites around the city, and problems with graffiti and rubbish appearing in the film. A car chase scene set along the banks of the Tiber River and through the streets of Rome featured an Aston Martin DB10 and a Jaguar C-X75. The C-X75 was originally developed as a hybrid electric vehicle with four independent electric engines powered by two jet turbines, before the project was cancelled. The version used for filming was converted to use a conventional internal combustion engine, to minimise the potential for disruption from mechanical problems with the complex hybrid system. The C-X75s used for filming were developed by the engineering division of Formula One racing team Williams, who built the original C-X75 prototype for Jaguar.

What company did the Williams Formula One team originally build the C-X75 prototype for?
---
A: Jaguar.

Problem: The first amniotes apparently arose in the Late Carboniferous. They descended from earlier reptiliomorph amphibious tetrapods, which lived on land that was already inhabited by insects and other invertebrates as well as by ferns, mosses and other plants. Within a few million years, two important amniote lineages became distinct: the synapsids, which would later include the common ancestor of the mammals; and the sauropsids, which would eventually come to include turtles, lizards, snakes, crocodilians, dinosaurs and birds. Synapsids have a single hole (temporal fenestra) low on each side of the skull.
When did amphibious tetrapods become prominent?

The original Latin word "universitas" refers in general to "a number of persons associated into one body, a society, company, community, guild, corporation, etc." At the time of the emergence of urban town life and medieval guilds, specialised "associations of students and teachers with collective legal rights usually guaranteed by charters issued by princes, prelates, or the towns in which they were located" came to be denominated by this general term. Like other guilds, they were self-regulating and determined the qualifications of their members.
Around the beginning of what two things did word universitas start to become prevalent?

Context and question: The Houston area is a leading center for building oilfield equipment. Much of its success as a petrochemical complex is due to its busy ship channel, the Port of Houston. In the United States, the port ranks first in international commerce and tenth among the largest ports in the world. Unlike most places, high oil and gasoline prices are beneficial for Houston's economy, as many of its residents are employed in the energy industry. Houston is the beginning or end point of numerous oil, gas, and products pipelines:
Where does the Port of Texas rank in international commerce?
Answer: unanswerable

Question: Other widely used alloys that contain zinc include nickel silver, typewriter metal, soft and aluminium solder, and commercial bronze. Zinc is also used in contemporary pipe organs as a substitute for the traditional lead/tin alloy in pipes. Alloys of 8588% zinc, 410% copper, and 28% aluminium find limited use in certain types of machine bearings. Zinc is the primary metal used in making American one cent coins since 1982. The zinc core is coated with a thin layer of copper to give the impression of a copper coin. In 1994, 33,200 tonnes (36,600 short tons) of zinc were used to produce 13.6 billion pennies in the United States.
Is there an answer to this question: What is the only metal used in pipe organs?

Answer: unanswerable

QUES: EU member countries have shown support for ambitious renewable energy goals. In 2010, Eurobarometer polled the twenty-seven EU member states about the target "to increase the share of renewable energy in the EU by 20 percent by 2020". Most people in all twenty-seven countries either approved of the target or called for it to go further. Across the EU, 57 percent thought the proposed goal was "about right" and 16 percent thought it was "too modest." In comparison, 19 percent said it was "too ambitious".
