Answer:
ARGUMENTS FOR AND AGAINST ANIMAL EXPERIMENTATION
For
1. Animals have always been used for experiments that are considered dangerous for humans, e.g lab rats.
This is necessary as some procedures are considered too dangerous for a human to undergo, and therefore, an animal is used to test the process.
2. Animals cannot talk, therefore, have no rights.
Animals, though living, do not have and enjoy the same rights that humans do according to the Universal Declaration of Human Rights. This makes it possible to subject them to experiments because no rights are being infringed upon.
Against
1. It is unethical and inhumane to use animals for experiments
Animals have feelings and as such should not be used for unsafe experiments. The practise is inhuman and unethical as it is done without the consent of the animal.
2. Animals are living things and so they have rights.
Animals are living and such should be considered to have rights just as humans do and it would be wrong for any scientist to get any animal of his choice to perform experiments.

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.
