Social Studies
1 answer:
Citrus2011 [14]3 years ago
3 0

Answer: The invention of the agricultural machine such as thresher, the green revolution.

Explanation:

  • The invention of the agricultural machinery of the peasants contributed to the development of farming activity. Scottish inventor Andrew Meikle designed the rig. This machine has made it easier to operate and increase productivity. The jigsaws, which separated the grain from the straw, became more efficient after 1850 when farmworkers hooked up the steam engines that propelled them.
  • In 1960, a green revolution occurred. Many high-yielding species have been invented to increase wheat and rice production, especially in densely populated countries such as India and China. Critics have argued that such a process is destroying the environment due to the excessive use of fertilizers and concentrating on only a few species. More recently, farmers have been rediscovering traditional farming methods and the use of organic fertilizers and pesticides.

Charra [1.4K]

Answer: unreliability

Explanation: Some of the problems that determine the quality of an experiment are reliability and validity.  

Reliability considers the consistency of the experiment. In the example above,  the result of the second sample is inconsistent with the result of the first sample, making Watt's research unreliable. That is, it does not reflect the ratings of a larger population. This problem can be solved by increasing the sample size, such that the average ratings are more reflective of a wider audience.

Validity considers the accuracy of the experiment. A lack of reliability of an experiment will likely make the result invalid as well, but this is not always the case.
