The correct answer is A. In the Old Stone Age
Explanation:
The Homo habilis was a species of hominid that preceded the Homo Sapiens (modern humans); this specie originated around 2.3 million years ago and lived in groups. Besides this, the Homo habilis was one of the first species to create tools using stone; indeed, it was found Homo habilis selected and cut stones to use these to cut meat or even plants. This important technological advance occurred during the Old Stone Age or Early Stone Age, which refers to the first period in which hominids created stones that occurred between 2.6 million years ago and 10,000 years ago. Thus, the Homo habilis first began using tools in the Old Stone Age.
The correct option is D. Volcanic eruption released large amounts of water vapor into Earth's early atmosphere.
Earth’s first atmosphere had lots of water vapor but it almost lacked oxygen. Eventually, frequent volcanic eruptions put several different gases into the air. These gases created a new type of atmosphere for Earth. The volcanic eruptions spewed gases such as nitrogen, carbon dioxide, hydrogen, and water vapor into the atmosphere, but no free oxygen. Without oxygen, there could not be life on Earth.
The two primary reasons the colonists gave for not wanting to declare their independence were 1) that they would be going up against the greatest military in the world (Britain), and that 2) they would loose their military protection.
