[Q]: Passage: Chloroplasts have their own DNA, often abbreviated as ctDNA, or cpDNA. It is also known as the plastome. Its existence was first proved in 1962, and first sequenced in 1986—when two Japanese research teams sequenced the chloroplast DNA of liverwort and tobacco. Since then, hundreds of chloroplast DNAs from various species have been sequenced, but they're mostly those of land plants and green algae—glaucophytes, red algae, and other algal groups are extremely underrepresented, potentially introducing some bias in views of 'typical' chloroplast DNA structure and content. Question: When was the first plastome sequenced?
[A]: 1986


[Q]: Passage: Under the terms of the Scotland Act 1978, an elected assembly would be set up in Edinburgh provided that the majority of the Scottish electorate voted for it in a referendum to be held on 1 March 1979 that represented at least 40% of the total electorate. The 1979 Scottish devolution referendum to establish a devolved Scottish Assembly failed. Although the vote was 51.6% in favour of a Scottish Assembly, this figure did not equal the 40% of the total electorate threshold deemed necessary to pass the measure, as 32.9% of the eligible voting population did not, or had been unable to, vote. Question: Where was an elected assembly to be set up, under the terms of the Scotland Act of 1978?
[A]: Edinburgh


[Q]: Passage: Southern California is home to Los Angeles International Airport, the second-busiest airport in the United States by passenger volume (see World's busiest airports by passenger traffic) and the third by international passenger volume (see Busiest airports in the United States by international passenger traffic); San Diego International Airport the busiest single runway airport in the world; Van Nuys Airport, the world's busiest general aviation airport; major commercial airports at Orange County, Bakersfield, Ontario, Burbank and Long Beach; and numerous smaller commercial and general aviation airports. Question: What ranking in terms of busiest airports from international passenger volume is the Los Angeles International Airport?
[A]:
third
