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: Deuterostomes differ from protostomes in several ways. Animals from both groups possess a complete digestive tract. However, in protostomes, the first opening of the gut to appear in embryological development (the archenteron) develops into the mouth, with the anus forming secondarily. In deuterostomes the anus forms first, with the mouth developing secondarily. In most protostomes, cells simply fill in the interior of the gastrula to form the mesoderm, called schizocoelous development, but in deuterostomes, it forms through invagination of the endoderm, called enterocoelic pouching. Deuterostome embryos undergo radial cleavage during cell division, while protostomes undergo spiral cleavage. Question: What do deuterostome embryos undergo during cell division?

A: radial cleavage

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 photosynthesisit 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: Drawing from his own experiences in Scouting, Spielberg helped the Boy Scouts of America develop a merit badge in cinematography in order to help promote filmmaking as a marketable skill. The badge was launched at the 1989 National Scout Jamboree, which Spielberg attended, and where he personally counseled many boys in their work on requirements. That same year, 1989, saw the release of Indiana Jones and the Last Crusade. The opening scene shows a teenage Indiana Jones in scout uniform bearing the rank of a Life Scout. Spielberg stated he made Indiana Jones a Boy Scout in honor of his experience in Scouting. For his career accomplishments, service to others, and dedication to a new merit badge Spielberg was awarded the Distinguished Eagle Scout Award. Question: Which Spielberg movie showed its main character was a Boy Scout?

A:
Indiana Jones and the Last Crusade
