Answer 1

Explanation:

Examples of natural-draught furnaces, in which gas buoyancy in a shaft of sufficient height induces a draught adequate to drive the smelting process4, are also known, but are generally regarded as disappointingly inefficient by comparison5. Here I report the discovery and excavation at Samanalawewa, Sri Lanka, of a previously unknown furnace type. The furnaces are all situated on the western margins of hills and ridges, where they are exposed to the strong monsoon winds. Field trials using replica furnaces confirm that this furnace type uses a wind-based air-supply principle that is distinct from either forced or natural draught, and show also that it is capable of producing high-carbon steel. This technology sustained a major industry in this area during the first millennium AD, and

what is the significance of classifying people in Germany as " without citizenship rights "​

Human rights constitute a concept that is similarly predicated on different

Explanation:

 how did the articles of confederation limit the power of the federal government

Answers

The Articles of Confederation was the first constitution for the United States. Along with this, it is known for being incredibly weak and giving little power to the federal government. Under the Articles of Confederation, the federal government could not tax the states, draft soldiers, regulate trade, or even amend and create new laws.

With the Articles of Confederation being so weak, many people started to realize that having a government that actually had power would be better and strengthen the power of the country as a whole. These people were called Federalists. On the other hand, people who wanted to keep the federal government limited and keep the power in the hands of the people were called Anti-Federalists.

When the Constitutional Convention of 1787 happened, the original goal was just to simply amend the Articles of Confederation. This obviously did not happen though, as the Articles of Confederation was scrapped as a whole and the United States Constitution was created instead, which gave power to the federal government.
