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.
Answer: E) separation of powers
Explanation:
The Line-item veto is a provision that allows an Executive authority such as a Governor or the President to cancel out parts of a bill enacted by Congress without having to veto the whole thing. Essentially it is a partial veto power that allows them to veto a bill only in part should they please.
Governors in 45 US States have this right but the President of the United States does not.
It is argued that this provision violates the principle of Separation of Powers amongst the Judiciary, the Legislature and the Executive.
This is because the Legislature should have exclusive power to construct the inner texts of a bill and the Executive should not be able to alter this content.
The correct answer is D; Southern state governments had taken steps to keep former slaves in inferior political, social, and economic statuses.
Further Explanation:
The states in the South were taking steps to keep all the former slaves from having the same rights as the white people. They were using the "Black Codes" that were made in 1865, two years before the reconstruction started.
The reconstruction did not end up helping the black people who were trying to find regular jobs, because the southern employers would still not hire them. After the reconstruction ended, southern states then started the Jim Crow laws.
