TASK DEFINITION: This task is about reading the given passage and construct a question about the information present in the passage. Construct a question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) its answer is a continuous text span from the paragraph. Avoid creating questions that (i) can be answered correctly without actually understanding the paragraph and (ii) uses same words or phrases given in the passage.
PROBLEM: While photosystem II photolyzes water to obtain and energize new electrons, photosystem I simply reenergizes depleted electrons at the end of an electron transport chain. Normally, the reenergized electrons are taken by NADP+, though sometimes they can flow back down more H+-pumping electron transport chains to transport more hydrogen ions into the thylakoid space to generate more ATP. This is termed cyclic photophosphorylation because the electrons are recycled. Cyclic photophosphorylation is common in C4 plants, which need more ATP than NADPH.

SOLUTION: What usually takes reenergized electrons?

PROBLEM: He attained a perfect score on the graduate school entrance exams to Princeton University in mathematics and physics—an unprecedented feat—but did rather poorly on the history and English portions. Attendees at Feynman's first seminar included Albert Einstein, Wolfgang Pauli, and John von Neumann. He received a PhD from Princeton in 1942; his thesis advisor was John Archibald Wheeler. Feynman's thesis applied the principle of stationary action to problems of quantum mechanics, inspired by a desire to quantize the Wheeler–Feynman absorber theory of electrodynamics, laying the groundwork for the "path integral" approach and Feynman diagrams, and was titled "The Principle of Least Action in Quantum Mechanics".

SOLUTION: Which two sections of the graduate exam did Feynman excel in?

PROBLEM: Bridgwater was developed during the Industrial Revolution as the area's leading port. The River Parrett was navigable by large ships as far as Bridgwater. Cargoes were then loaded onto smaller boats at Langport Quay, next to the Bridgwater Bridge, to be carried further up river to Langport; or they could turn off at Burrowbridge and then travel via the River Tone to Taunton. The Parrett is now only navigable as far as Dunball Wharf. Bridgwater, in the 19th and 20th centuries, was a centre for the manufacture of bricks and clay roof tiles, and later cellophane, but those industries have now stopped. With its good links to the motorway system, Bridgwater has developed as a distribution hub for companies such as Argos, Toolstation, Morrisons and Gerber Juice. AgustaWestland manufactures helicopters in Yeovil, and Normalair Garratt, builder of aircraft oxygen systems, is also based in the town. Many towns have encouraged small-scale light industries, such as Crewkerne's Ariel Motor Company, one of the UK's smallest car manufacturers.
