Problem: Please answer a question about the following article about Richard Feynman:
Feynman devoted the latter half of his book What Do You Care What Other People Think? to his experience on the Rogers Commission, straying from his usual convention of brief, light-hearted anecdotes to deliver an extended and sober narrative. Feynman's account reveals a disconnect between NASA's engineers and executives that was far more striking than he expected. His interviews of NASA's high-ranking managers revealed startling misunderstandings of elementary concepts. For instance, NASA managers claimed that there was a 1 in 100,000 chance of a catastrophic failure aboard the shuttle, but Feynman discovered that NASA's own engineers estimated the chance of a catastrophe at closer to 1 in 200. He concluded that the space shuttle reliability estimate by NASA management was fantastically unrealistic, and he was particularly angered that NASA used these figures to recruit Christa McAuliffe into the Teacher-in-Space program. He warned in his appendix to the commission's report (which was included only after he threatened not to sign the report), "For a successful technology, reality must take precedence over public relations, for nature cannot be fooled."
While the higher-ups said a failure was unlikely, at 1 in 100,000 odds, the scientists felt the odd were what?
A: 1 in 200
Problem: Please answer a question about the following article about 2008 Sichuan earthquake:
In terms of school casualties, thousands of school children died due to shoddy construction. In Mianyang City, seven schools collapsed, burying at least 1,700 people. At least 7,000 school buildings throughout the province collapsed. Another 700 students were buried in a school in Hanwang. At least 600 students and staff died at Juyuan Elementary School. Up to 1,300 children and teachers died at Beichuan Middle School.
How many people were buried under rubble in Mianyang City?
A: 1,700
Problem: Please answer a question about the following article about Josip Broz Tito:
In the autumn of 1913, he was conscripted into the Austro-Hungarian Army. He was sent to a school for non-commissioned officers and became a sergeant, serving in the 25th Croatian Regiment based in Zagreb. In May 1914, Broz won a silver medal at an army fencing competition in Budapest. At the outbreak of World War I in 1914, he was sent to Ruma, where he was arrested for anti-war propaganda and imprisoned in the Petrovaradin fortress. In January 1915, he was sent to the Eastern Front in Galicia to fight against Russia. He distinguished himself as a capable soldier, becoming the youngest Sergeant Major in the Austro-Hungarian Army. For his bravery in the face of the enemy, he was recommended for the Silver Bravery Medal but was taken prisoner of war before it could be formally presented. On 25 March 1915, while in Bukovina, he was seriously wounded and captured by the Russians.
What position in the army did he become after office school?
A: sergeant
Problem: Please answer a question about the following article about Gene:
Although the number of base-pairs of DNA in the human genome has been known since the 1960s, the estimated number of genes has changed over time as definitions of genes, and methods of detecting them have been refined. Initial theoretical predictions of the number of human genes were as high as 2,000,000. Early experimental measures indicated there to be 50,000–100,000 transcribed genes (expressed sequence tags). Subsequently, the sequencing in the Human Genome Project indicated that many of these transcripts were alternative variants of the same genes, and the total number of protein-coding genes was revised down to ~20,000 with 13 genes encoded on the mitochondrial genome. Of the human genome, only 1–2% consists of protein-coding genes, with the remainder being 'noncoding' DNA such as introns, retrotransposons, and noncoding RNAs.
What sort of variants did the Human Genome Project indicate that many of the measured transcripts were?
A:
alternative variants
