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.

Q: 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?

A: when the oxygen concentration is too high

Q: Passage: The Roman Empire expanded to include different peoples and cultures; in principle, Rome followed the same inclusionist policies that had recognised Latin, Etruscan and other Italian peoples, cults and deities as Roman. Those who acknowledged Rome's hegemony retained their own cult and religious calendars, independent of Roman religious law. Newly municipal Sabratha built a Capitolium near its existing temple to Liber Pater and Serapis. Autonomy and concord were official policy, but new foundations by Roman citizens or their Romanised allies were likely to follow Roman cultic models. Romanisation offered distinct political and practical advantages, especially to local elites. All the known effigies from the 2nd century AD forum at Cuicul are of emperors or Concordia. By the middle of the 1st century AD, Gaulish Vertault seems to have abandoned its native cultic sacrifice of horses and dogs in favour of a newly established, Romanised cult nearby: by the end of that century, Sabratha’s so-called tophet was no longer in use. Colonial and later Imperial provincial dedications to Rome's Capitoline Triad were a logical choice, not a centralised legal requirement. Major cult centres to "non-Roman" deities continued to prosper: notable examples include the magnificent Alexandrian Serapium, the temple of Aesculapeus at Pergamum and Apollo's sacred wood at Antioch. Question: What was Rome's policy towards government?

A: Autonomy and concord

Q: Passage: In 1918 Whitehead's academic responsibilities began to seriously expand as he accepted a number of high administrative positions within the University of London system, of which Imperial College London was a member at the time. He was elected Dean of the Faculty of Science at the University of London in late 1918 (a post he held for four years), a member of the University of London's Senate in 1919, and chairman of the Senate's Academic (leadership) Council in 1920, a post which he held until he departed for America in 1924. Whitehead was able to exert his newfound influence to successfully lobby for a new history of science department, help establish a Bachelor of Science degree (previously only Bachelor of Arts degrees had been offered), and make the school more accessible to less wealthy students. Question: Where did Whitehead accept administrative positions?

A:
University of London
