Problem: New Haven, Connecticut:

Near New Haven there is the static inverter plant of the HVDC Cross Sound Cable. There are three PureCell Model 400 fuel cells placed in the city of New Haven—one at the New Haven Public Schools and newly constructed Roberto Clemente School, one at the mixed-use 360 State Street building, and one at City Hall. According to Giovanni Zinn of the city's Office of Sustainability, each fuel cell may save the city up to $1 million in energy costs over a decade. The fuel cells were provided by ClearEdge Power, formerly UTC Power.

In terms of budget, what is the estimated savings from using the fuel cell system?
---
A: $1 million in energy costs


Problem: Traditionally the annelids have been divided into two major groups, the polychaetes and clitellates. In turn the clitellates were divided into oligochaetes, which include earthworms, and hirudinomorphs, whose best-known members are leeches. For many years there was no clear arrangement of the approximately 80 polychaete families into higher-level groups. In 1997 Greg Rouse and Kristian Fauchald attempted a "first heuristic step in terms of bringing polychaete systematics to an acceptable level of rigour", based on anatomical structures, and divided polychaetes into:

Amensalism is an interaction where an organism inflicts harm to another organism without any costs or benefits received by the other. A clear case of amensalism is where sheep or cattle trample grass. Whilst the presence of the grass causes negligible detrimental effects to the animal's hoof, the grass suffers from being crushed. Amensalism is often used to describe strongly asymmetrical competitive interactions, such as has been observed between the Spanish ibex and weevils of the genus Timarcha which feed upon the same type of shrub. Whilst the presence of the weevil has almost no influence on food availability, the presence of ibex has an enormous detrimental effect on weevil numbers, as they consume significant quantities of plant matter and incidentally ingest the weevils upon it.
What happens if a weevil eats from an ibex?
A: unanswerable


Context and question: Slack (2003) compares three groups that conducted biological research at Yale during overlapping periods between 1910 and 1970. Yale proved important as a site for this research. The leaders of these groups were Ross Granville Harrison, Grace E. Pickford, and G. Evelyn Hutchinson, and their members included both graduate students and more experienced scientists. All produced innovative research, including the opening of new subfields in embryology, endocrinology, and ecology, respectively, over a long period of time. Harrison's group is shown to have been a classic research school; Pickford's and Hutchinson's were not. Pickford's group was successful in spite of her lack of departmental or institutional position or power. Hutchinson and his graduate and postgraduate students were extremely productive, but in diverse areas of ecology rather than one focused area of research or the use of one set of research tools. Hutchinson's example shows that new models for research groups are needed, especially for those that include extensive field research.
What information didn't Hutchinson's model provide?

Question: His film appearances after becoming Governor of California included a three-second cameo appearance in The Rundown, and the 2004 remake of Around the World in 80 Days. In 2005, he appeared as himself in the film The Kid & I. He voiced Baron von Steuben in the Liberty's Kids episode "Valley Forge". He had been rumored to be appearing in Terminator Salvation as the original T-800; he denied his involvement, but he ultimately did appear briefly via his image being inserted into the movie from stock footage of the first Terminator movie. Schwarzenegger appeared in Sylvester Stallone's The Expendables, where he made a cameo appearance.
Is there an answer to this question: Which 2005 movie featured Schwarzenegger as himself?

Answer: The Kid & I
