How does the​ audience impact how Frederich Engels and Karl Marx present their ideas​?
algol13

Answer:

The intended audience of the communist manifesto were urban workers. Because the manifesto was first published in German, the more specific audience were German urban workers. Germany was industrializing very fast at the time, so the potential audience was quite large.

Because the working class is not necessarily as intellectual as a doctor in philosophy like Karl Marx was, or a successful businessman and writer like Engels, the language that Marx and Engels use in the manifesto is clear, simple, and the main intention is to explain, briefly and clearly, their ideas about society, about the economy, and about the situation of the working class and their relationship with the capitalist class.

Because it is a manifesto, its main goal is to promote an idea, and an action: the idea was that capitalism is a mode of production that exploits the working class, and therefore, is unfair, and the action was the mobilization of the working class against capitalism, and for the promotion of another social system (first socialism, then communism).

Hope this helps, have a wonderful day/night, stay safe, happy holidays, and merry christmas!

In the system of share-tenancy, farmworkers_____. A. did not choose the crops they planted. B. had more control over their crops
marusya05 [52]
I believe the answer is: <span>B. had more control over their crops and supplies than was true in sharecropping. 

In the share tenancy system, the farmers usually operate the land that is owned by other people, and they are required to give some percentage of the harvest to the owners as payment. 
In this system, the owner would give the farmers with full freedom on the technique and operation of the land.

Which is most likely to cause confusion, hinder thinking, and prevent quick access to resources in a study environment?
Paladinen [302]

Answer:

I would say C, noise.

Explanation:

This is because noise, such as loud speaking, are distractions towards work, studying, and other things that involved the process of thinking. when you are doing a test for example and the entire class is talking, it's a bit harder to exceed at your test because of all the commotion around you. Let's say your in a library, as you may know, everyone is quiet and if people are talking librarians would say "shhhhh". its for the reason of people studying, reading, doing work, etc, that you have to stay quite son they can focus as much as possible.
