The correct answer is: "they started trading with neighboring communities".
The first stage of an agricultural society is characterized by a subsistence agricultural economy, in which everybody in the community contributes to production activities. Once they are able to develop better farming techniques, the amount produced increases and production surpluses are generated. These surpluses are the amount that is not necessary for self-subsistence and that can be traded in exchange for other commodities.
When trade steps in, it means that there are different types of products in the economy. Division of labor and speacialization appear at this point, when different tasks need to be done to produce each good, and different people work on each of them. Some people continue doing the agricultural work, others are in charge of the trading activities, and some others become artisans which construct tools that continue improving the production techniques and generating more surpluses.
The answer is: Extinction
In psycchology, extinction refers to a situation when a conditioned response that result in a certain behavior starts to fade away.
When conditioned stimulus exists without the unconditioned stimulus, the brain will have no basic response toward that certain stimulus, which will cause the extinction.
Answer:
fail to reject the null hypothesis and make a type II error
Explanation:
Even if a treatment is effective in the real world (it has an effect), it is still possible to obtain a sample mean that is so similar to the population mean that the sample mean doesn't fall in the critical, or rejection, region. If this happens, you are likely to <u>fail to reject the null hypothesis and make a type II error</u>.
Since that sample mean is so similar to the population mean, the treatment effect may not be detected on analysis even though it is infact significant, this will cause the research to erroneously concluded that the treatment effect is zero and accept the null hypothesis when it is actually not zero. This is a type II error. Type II error in statistics means the non-rejection of a false null hypothesis and type I error is the rejection of a correct null hypothesis.
Answer:
intimacy versus isolation
Explanation:
In the intimacy versus isolation stage a person explores their relationships with other people.
There are two results of this stage.
A person makes lasting relationships with people and is happy.
A person fears the what being intimate might mean and rejects all forms of relationships. This likely would lead to depression, loneliness and isolation.
Here, Devin is cautious about relationships and makes sure that he does not get hurt during the relationship. Hence is in the intimacy versus isolation stage.
