Question: Dryer and rockier uplands and ridges are occupied by oak-chestnut type forests dominated by a variety of oaks (Quercus spp.), hickories (Carya spp.) and, in the past, by the American chestnut (Castanea dentata). The American chestnut was virtually eliminated as a canopy species by the introduced fungal chestnut blight (Cryphonectaria parasitica), but lives on as sapling-sized sprouts that originate from roots, which are not killed by the fungus. In present-day forest canopies chestnut has been largely replaced by oaks.
Is there an answer to this question: Where does the fungus originate from?

Answer: unanswerable

Question: A report released in January 2011 by the Diario de Noticias and published in Portugal by Gradiva, had demonstrated that in the period between the Carnation Revolution in 1974 and 2010, the democratic Portuguese Republic governments encouraged over-expenditure and investment bubbles through unclear Publicprivate partnerships and funding of numerous ineffective and unnecessary external consultancy and advisory of committees and firms. This allowed considerable slippage in state-managed public works and inflated top management and head officer bonuses and wages. Persistent and lasting recruitment policies boosted the number of redundant public servants. Risky credit, public debt creation, and European structural and cohesion funds were mismanaged across almost four decades.
Is there an answer to this question: By whom was a report published in 2011 that demonstrated the Portuguese government encouraged over-expenditure and investment bubbles?

Answer: Diario de Noticias

Question: Imperial College London is a public research university located in London, United Kingdom. It was founded by Prince Albert who envisioned an area composed of the Natural History Museum, Science Museum, Victoria and Albert Museum, Royal Albert Hall and the Imperial Institute. The Imperial Institute was opened by his wife, Queen Victoria, who laid the first stone. In 1907, Imperial College London was formed by Royal Charter, and soon joined the University of London, with a focus on science and technology. The college has expanded its coursework to medicine through mergers with St Mary's Hospital. In 2004, Queen Elizabeth II opened the Imperial College Business School. Imperial became an independent university from the University of London during its one hundred year anniversary.
Is there an answer to this question: Which document allowed the Imperial College London to be formed?

Answer: Royal Charter

Question: A commutator is a mechanism used to switch the input of most DC machines and certain AC machines consisting of slip ring segments insulated from each other and from the electric motor's shaft. The motor's armature current is supplied through the stationary brushes in contact with the revolving commutator, which causes required current reversal and applies power to the machine in an optimal manner as the rotor rotates from pole to pole. In absence of such current reversal, the motor would brake to a stop. In light of significant advances in the past few decades due to improved technologies in electronic controller, sensorless control, induction motor, and permanent magnet motor fields, electromechanically commutated motors are increasingly being displaced by externally commutated induction and permanent-magnet motors.
Is there an answer to this question: What two motor types are descendant today?

Answer:
unanswerable
