Answer:
The black hole in the nucleus of the Milky Way Galaxy could not be the remnant of a single dead star.
Explanation:
The very center of the galaxy is known as the nucleus of the galaxy. The nucleus of the galaxy is hidden due to the dust particles present in the galaxy, which eventually covers the light of the nucleus.
The nucleus of the galaxy is filled with numerous stars and dust and the radiation emitted by them. The black hole lies at the center of the galaxy.
<u>These super-massive black holes could not be the remnant of a single dead star because these holes are very large.</u>

Quaternary period
Explanation:
The last Ice Age on Earth occurred during the Quaternary period. This Ice Age only ended around 10,000 years BC, so very recently. During this period, big portions of the Earth were under ice, with approximately half of North America, as well as half of Eurasia being covered in ice. The mountains around the globe too were covered in glaciers. Because there was so much water trapped in the ice sheets and glaciers, the sea levels were much lower, which opened up lot of land-bridges between the islands and continents, which turned out to be crucial for the human migrations around the globe.
