Question: USB connections also come in five data transfer modes, in ascending order: Low Speed (1.0), Full Speed (1.0), High Speed (2.0), SuperSpeed (3.0), and SuperSpeed+ (3.1). High Speed is supported only by specifically designed USB 2.0 High Speed interfaces (that is, USB 2.0 controllers without the High Speed designation do not support it), as well as by USB 3.0 and newer interfaces. SuperSpeed is supported only by USB 3.0 and newer interfaces, and requires a connector and cable with extra pins and wires, usually distinguishable by the blue inserts in connectors.
Is there an answer to this question: USB connections come in what?

Answer: five data transfer modes

Question: In the late renaissance various writers began to question the medieval and classical understanding of knowledge acquisition in a more fundamental way. In political and historical writing Niccolo Machiavelli and his friend Francesco Guicciardini initiated a new realistic style of writing. Machiavelli in particular was scornful of writers on politics who judged everything in comparison to mental ideals and demanded that people should study the "effectual truth" instead. Their contemporary, Leonardo da Vinci (14521519) said, "If you find from your own experience that something is a fact and it contradicts what some authority has written down, then you must abandon the authority and base your reasoning on your own findings."
Is there an answer to this question: What did da Vinci advise when your experience contradicted authority?

Answer: abandon the authority and base your reasoning on your own findings

Question: The relationship between ethnic Greek identity and Greek Orthodox religion continued after the creation of the Modern Greek state in 1830. According to the second article of the first Greek constitution of 1822, a Greek was defined as any Christian resident of the Kingdom of Greece, a clause removed by 1840. A century later, when the Treaty of Lausanne was signed between Greece and Turkey in 1923, the two countries agreed to use religion as the determinant for ethnic identity for the purposes of population exchange, although most of the Greeks displaced (over a million of the total 1.5 million) had already been driven out by the time the agreement was signed.[note 1] The Greek genocide, in particular the harsh removal of Pontian Greeks from the southern shore area of the Black Sea, contemporaneous with and following the failed Greek Asia Minor Campaign, was part of this process of Turkification of the Ottoman Empire and the placement of its economy and trade, then largely in Greek hands under ethnic Turkish control.
Is there an answer to this question: When was the original Grecian constitution formed ?

Answer: first Greek constitution of 1822

Question: Copper has been in use at least 10,000 years, but more than 95% of all copper ever mined and smelted has been extracted since 1900, and more than half was extracted in only the last 24 years. As with many natural resources, the total amount of copper on Earth is vast (around 1014 tons just in the top kilometer of Earth's crust, or about 5 million years' worth at the current rate of extraction). However, only a tiny fraction of these reserves is economically viable, given present-day prices and technologies. Various estimates of existing copper reserves available for mining vary from 25 years to 60 years, depending on core assumptions such as the growth rate. Recycling is a major source of copper in the modern world. Because of these and other factors, the future of copper production and supply is the subject of much debate, including the concept of peak copper, analogous to peak oil.
Is there an answer to this question: How long has copper been in use?

Answer:
at least 10,000 years
