Problem: Elevator:

Double deck elevators are used in the Taipei 101 office tower. Tenants of even-numbered floors first take an escalator (or an elevator from the parking garage) to the 2nd level, where they will enter the upper deck and arrive at their floors. The lower deck is turned off during low-volume hours, and the upper deck can act as a single-level elevator stopping at all adjacent floors. For example, the 85th floor restaurants can be accessed from the 60th floor sky-lobby. Restaurant customers must clear their reservations at the reception counter on the 2nd floor. A bank of express elevators stop only on the sky lobby levels (36 and 60, upper-deck car), where tenants can transfer to "local" elevators.

During the low volume hours, what can the upper deck function as?
---
A: a single-level elevator stopping at all adjacent floors

Problem: A boy who is late for any division or other appointment may be required to sign "Tardy Book", a register kept in the School Office, between 7.35am and 7.45am, every morning for the duration of his sentence (typically three days). Tardy Book may also be issued for late work. For more serious misdeeds, a boy is summoned from his lessons to the Head Master, or Lower Master if the boy is in the lower two years, to talk personally about his misdeeds. This is known as the "Bill". The most serious misdeeds may result in expulsion, or rustication (suspension). Conversely, should a master be more than 15 minutes late for a class, traditionally the pupils might claim it as a "run" and absent themselves for the rest of its duration.
What term is used if a master is more than 15 minutes late to a class?
---
Answer: a "run"

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
After several failed attempts, in 1930 the first aeroplane reached Bermuda. A Stinson Detroiter seaplane flying from New York, it had to land twice in the ocean: once because of darkness and again to refuel. Navigation and weather forecasting improved in 1933 when the Royal Air Force (then responsible for providing equipment and personnel for the Royal Navy's Fleet Air Arm) established a station at the Royal Naval Dockyard to repair (and supply replacement) float planes for the fleet. In 1936 Luft Hansa began to experiment with seaplane flights from Berlin via the Azores with continuation to New York City.
What is Detroiter Stinson a type of?
A: unanswerable

Context and question: Shell sold 9.5% of its 23.1% stake in Woodside Petroleum in June 2014 and advised that it had reached an agreement for Woodside to buy back 9.5% of its shares at a later stage. Shell became a major shareholder in Woodside after a 2001 takeover attempt was blocked by then federal Treasurer Peter Costello and the corporation has been open about its intention to sell its stake in Woodside as part of its target to shed assets. At a general body meeting, held on 1 August 2014, 72 percent of shareholders voted to approve the buy-back, short of the 75 percent vote that was required for approval. A statement from Shell read: "Royal Dutch Shell acknowledges the outcome of Woodside Petroleum Limited's shareholders' negative vote on the selective buy-back proposal. Shell is reviewing its options in relation to its remaining 13.6 percent holding."
Shell became a major shareholder in Woodside after a takeover attempt was blocked in what year?

Question: In May 2005, GE announced the launch of a program called "Ecomagination," intended, in the words of CEO Jeff Immelt "to develop tomorrow's solutions such as solar energy, hybrid locomotives, fuel cells, lower-emission aircraft engines, lighter and stronger durable materials, efficient lighting, and water purification technology". The announcement prompted an op-ed piece in The New York Times to observe that, "while General Electric's increased emphasis on clean technology will probably result in improved products and benefit its bottom line, Mr. Immelt's credibility as a spokesman on national environmental policy is fatally flawed because of his company's intransigence in cleaning up its own toxic legacy."
Is there an answer to this question: When did GE announce its Ecoimagination program?

Answer:
May 2005
