Question: "1,000 kg" Context: "Copper is synthesized in massive stars and is present in the Earth's crust at a concentration of about 50 parts per million (ppm), where it occurs as native copper or in minerals such as the copper sulfides chalcopyrite and chalcocite, the copper carbonates azurite and malachite, and the copper(I) oxide mineral cuprite. The largest mass of elemental copper discovered weighed 420 tonnes and was found in 1857 on the Keweenaw Peninsula in Michigan, US. Native copper is a polycrystal, with the largest described single crystal measuring 4.43.23.2 cm." Answer:
Ans: tonnes

Question: "What got less warm when the landmasses were connected?" Context: "South America became linked to North America through the Isthmus of Panama during the Pliocene, bringing a nearly complete end to South America's distinctive marsupial faunas. The formation of the Isthmus had major consequences on global temperatures, since warm equatorial ocean currents were cut off and an Atlantic cooling cycle began, with cold Arctic and Antarctic waters dropping temperatures in the now-isolated Atlantic Ocean. Africa's collision with Europe formed the Mediterranean Sea, cutting off the remnants of the Tethys Ocean. Sea level changes exposed the land-bridge between Alaska and Asia. Near the end of the Pliocene, about 2.58 million years ago (the start of the Quaternary Period), the current ice age began. The polar regions have since undergone repeated cycles of glaciation and thaw, repeating every 40,000100,000 years." Answer:
Ans: Atlantic

Question: "If someone has testosterone released, what characteristics would develop?" Context: "Puberty occurs through a long process and begins with a surge in hormone production, which in turn causes a number of physical changes. It is the stage of life characterized by the appearance and development of secondary sex characteristics (for example, a deeper voice and larger adam's apple in boys, and development of breasts and more curved and prominent hips in girls) and a strong shift in hormonal balance towards an adult state. This is triggered by the pituitary gland, which secretes a surge of hormonal agents into the blood stream, initiating a chain reaction to occur. The male and female gonads are subsequently activated, which puts them into a state of rapid growth and development; the triggered gonads now commence the mass production of the necessary chemicals. The testes primarily release testosterone, and the ovaries predominantly dispense estrogen. The production of these hormones increases gradually until sexual maturation is met. Some boys may develop gynecomastia due to an imbalance of sex hormones, tissue responsiveness or obesity." Answer:
Ans: a deeper voice and larger adam's apple

Question: "Which location is closer to Paris, London or Calais?" Context: "Paris is located in northern central France. By road it is 450 kilometres (280 mi) south-east of London, 287 kilometres (178 mi) south of Calais, 305 kilometres (190 mi) south-west of Brussels, 774 kilometres (481 mi) north of Marseille, 385 kilometres (239 mi) north-east of Nantes, and 135 kilometres (84 mi) south-east of Rouen. Paris is located in the north-bending arc of the river Seine and includes two islands, the Ile Saint-Louis and the larger Ile de la Cite, which form the oldest part of the city. The river's mouth on the English Channel (La Manche) is about 233 mi (375 km) downstream of the city, established around 7600 BC. The city is spread widely on both banks of the river. Overall, the city is relatively flat, and the lowest point is 35 m (115 ft) above sea level. Paris has several prominent hills, the highest of which is Montmartre at 130 m (427 ft). Montmartre gained its name from the martyrdom of Saint Denis, first bishop of Paris, atop the Mons Martyrum, "Martyr's mound", in 250." Answer:
Ans: Calais
