question:
Passage: The first amniotes apparently arose in the Late Carboniferous. They descended from earlier reptiliomorph amphibious tetrapods, which lived on land that was already inhabited by insects and other invertebrates as well as by ferns, mosses and other plants. Within a few million years, two important amniote lineages became distinct: the synapsids, which would later include the common ancestor of the mammals; and the sauropsids, which would eventually come to include turtles, lizards, snakes, crocodilians, dinosaurs and birds. Synapsids have a single hole (temporal fenestra) low on each side of the skull.
answer:
From what period did the first insects come from?

question:
Passage: In 1986, Nintendo released the Famicom Disk System (FDS) in Japan, a type of floppy drive that uses a single-sided, proprietary 5 cm (2") disk and plugs into the cartridge port. It contains RAM for the game to load into and an extra single-cycle wavetable-lookup sound chip. The disks were originally obtained from kiosks in malls and other public places where buyers could select a title and have it written to the disk. This process would cost less than cartridges and users could take the disk back to a vending booth and have it rewritten with a new game. The disks were used both for storing the game and saving progress and total capacity was 128k (64k per side).
answer:
What year did Atari release the Famicom Disk System?

Passage: For many years Arsenal's away colours were white shirts and either black or white shorts. In the 196970 season, Arsenal introduced an away kit of yellow shirts with blue shorts. This kit was worn in the 1971 FA Cup Final as Arsenal beat Liverpool to secure the double for the first time in their history. Arsenal reached the FA Cup final again the following year wearing the red and white home strip and were beaten by Leeds United. Arsenal then competed in three consecutive FA Cup finals between 1978 and 1980 wearing their "lucky" yellow and blue strip, which remained the club's away strip until the release of a green and navy away kit in 198283. The following season, Arsenal returned to the yellow and blue scheme, albeit with a darker shade of blue than before.
answer:
What away color socks did Arsenal wear for many years?
