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.

The theorist who believed that children learn language when they are reinforced by parental attention was B.F.Skinner.
B.F.Skinner was a celebrated American psychologist who advanced the behaviorist theory of learning. This theory is based on the idea that learning occurs through a method of ‘conditioning’, which when stimulus, rewards, and punishments are combined to drive the learning process.
The conditioning relies on what Skinner calls reinforcement. Reinforcement is of two types, namely positive reinforcers, which are the rewards after meeting a target, and negative reinforcers, which refers to the unpleasant consequences of failing to meet the target.
Actions that are followed by negative reinforcers tend to weaken, while those followed by positive reinforcers tend to be repeated. For example, children can be encouraged to learn language if they receive consistent positive reinforcement from their parents every time they learn a new word or phrase.
