This task is about writing a correct answer for the reading comprehension task. Based on the information provided in a given passage, you should identify the shortest continuous text span from the passage that serves as an answer to the given question. Avoid answers that are incorrect or provides incomplete justification for the question.

Input: Consider Input: Passage: Photorespiration can occur when the oxygen concentration is too high. Rubisco cannot distinguish between oxygen and carbon dioxide very well, so it can accidentally add O2 instead of CO2 to RuBP. This process reduces the efficiency of photosynthesis—it consumes ATP and oxygen, releases CO2, and produces no sugar. It can waste up to half the carbon fixed by the Calvin cycle. Several mechanisms have evolved in different lineages that raise the carbon dioxide concentration relative to oxygen within the chloroplast, increasing the efficiency of photosynthesis. These mechanisms are called carbon dioxide concentrating mechanisms, or CCMs. These include Crassulacean acid metabolism, C4 carbon fixation, and pyrenoids. Chloroplasts in C4 plants are notable as they exhibit a distinct chloroplast dimorphism. Question: When does photorespiration happen?

Output: when the oxygen concentration is too high


Input: Consider Input: Passage: In response to Cusumano's perspective, Screen Producers Australia executive director Matt Deaner clarified the motivation of the film industry: "Distributors are usually wanting to encourage cinema-going as part of this process [monetizing through returns] and restrict the immediate access to online so as to encourage the maximum number of people to go to the cinema." Deaner further explained the matter in terms of the Australian film industry, stating: "there are currently restrictions on quantities of tax support that a film can receive unless the film has a traditional cinema release." Question: Who made clear the motivations of the filmmakers?

Output: Matt Deaner


Input: Consider Input: Passage: Most historians today, including John's recent biographers Ralph Turner and Lewis Warren, argue that John was an unsuccessful monarch, but note that his failings were exaggerated by 12th- and 13th-century chroniclers. Jim Bradbury notes the current consensus that John was a "hard-working administrator, an able man, an able general", albeit, as Turner suggests, with "distasteful, even dangerous personality traits", including pettiness, spitefulness and cruelty. John Gillingham, author of a major biography of Richard I, follows this line too, although he considers John a less effective general than do Turner or Warren, and describes him "one of the worst kings ever to rule England". Bradbury takes a moderate line, but suggests that in recent years modern historians have been overly lenient towards John's numerous faults. Popular historian Frank McLynn maintains a counter-revisionist perspective on John, arguing that the king's modern reputation amongst historians is "bizarre", and that as a monarch John "fails almost all those [tests] that can be legitimately set". Question: John Gillingham considers John what?


Output: a less effective general
