What lead many citizens of eastern europe nations to rebel against their communist governments

Answers

There are multiple answers to that question... Since it seems they expect you to list common factors for the Eastern European dissatisfaction with their communist governments rather than choosing one from a multiple choice list, here are some possible answers:
- Most communist regimes were comprised (and dominated) by small groups of individuals who refused many communist beliefs.
- The economic situation of Eastern European communist countries was really deplorable, and their citizens realized this through the media (TV, newspapers, etc..)
- Certain ideological, religious groups (such as the Polish Catholic Church) provided some leadership to the opposition.
- These countries could not compete with capitalist Western countries in terms of economy and medicine.
- Americans made promises to the new countries after they got rid of communism; letting multi-nationalism take over.
1) Living conditions: Living conditions were hard, as many famiilies didn't have anything special (they worked pretty much the same, in the fields or in factories and such). Food were eaten in a big ol' room, and they usually slept in a large house. Living conditions became worse and worse as time grew on.
2) Mistreatment: Many citizens felt that they were mistreated and that they didn't have enough rights, and so they tried to protest. Of course that was knocked down, and so they were all the more angry.
3) Help from the NATO and US; As the US promised satellite nations of USSR that if they broke away, they would be able to enter into the Marshall Plan (a plan that lent money too countries to help them rebuild) Because USSR really didn't help their satellite nations much in a way, many broke away to try to rebuild both their country, political system, and the way they run things.

"all college students who drink beer make less than a 4.0 g.p.a. it is obvious then that drinking beer lowers a student's grades." this is an example of someone who believes that

Answers

This is an example of someone who believes that correlation proves causation.
Correlation between the GPA of students who drink beer and the GPA of those who don't according to this person will cause the belief that beer is the reason why their GPA is lower than those students who don't drink beer, which doesn't make much sense.

Final answer:

The statement assumes a direct cause-and-effect relationship between beer drinking and lower grades, overlooking the influence of perception on behavior and the variability of individual academic performance. It fails to consider misperceived norms and other factors that may also impact a student's GPA.

Explanation:

The statement "all college students who drink beer make less than a 4.0 GPA, it is obvious then that drinking beer lowers a student's grades" is an example of a flawed cause-and-effect assumption. This assumption erroneously infers that beer drinking directly causes lower grades without considering other potential factors that may influence a student's academic performance. It also overlooks the impact of perception on behavior, particularly in the context of binge drinking among college students, where misperceived norms can significantly influence individual consumption patterns and subsequently, academic performance.

Research shows that excessive drinking is a serious problem on many campuses, with many students overestimating the descriptive norm for college student drinking. This overestimation can lead to an increase in alcohol consumption, in the belief that they are drinking less than their peers. However, providing students with accurate information about drinking norms has been found to reduce overindulgent drinking, highlighting the importance of understanding and addressing the roots of misperceived norms rather than simply attributing poor academic performance to alcohol consumption alone.

He believes when children first become in agreement to other people’s faults, this feeling goes innermost to become an fascination with what others consider about their own personal faults. Imaginary audience is the tenure for the affinity of young teenagers to feel that every person is viewing their action; a constituent of adolescent egocentrism. Personal fable is the tenure for the affinity of young teenagers to believe that their existence is distinctive and heroic; a constituent of adolescent egocentrism.

Final answer:

Teenagers question society's rules and become involved in idealistic causes because it is a part of their psychosocial development, where they work through forming their identity and independence, influenced by peer relationships and a natural inclination for risk-taking.

Explanation:

According to developmental psychologist David Elkind, teenagers question society's rules and become involved in idealistic causes as part of their psychosocial development. During adolescence, individuals develop the ability to think abstractly and begin to establish a sense of who they are as individuals, leading to increased independence from their parents.

Erik Erikson's theory of psychosocial development specifically addresses this stage as one of identity versus role confusion, where adolescents grapple with questions like "Who am I?" and "What do I want to do with my life?" As they navigate this stage, peer influence becomes significantly more important, which, combined with a natural propensity for risk-taking, could lead them to challenge societal norms and engage with idealistic causes to form their own identities.

These behaviors and inclinations are also influenced by changes in hormonal levels, causing mood swings, and the newfound ability to engage in logical reasoning and solve hypothetical problems. It is also suggested that there is an evolutionary basis to this stage, as risk-taking behaviors might have historically helped adolescents to leave their family of origin and establish their own family.

A researcher studying public opinion of proposed social security changes obtains a simple random sample of 5050 adult americans and asks them whether or not they support the proposed changes. to say that the distribution of the sample proportion of adults who respond? yes, is approximately? normal, how many more adult americans does the researcher need to sample in the following? cases? ?(a) 10?% of all adult americans support the changes ?(b) 15?% of all adult americans support the changes

Answers

The researcher must add at least 7 more adults to the sample to make it a random and simple distribution.

When the condition of all random values having equal probability occurs then the type of distribution is simple distribution.

Given scenarios:

(a )People who supported the change (p1) is 10% or 0.10

(b) People who supported the change is (p2) 15% or 0.15

The sample size or n is 50.

Therefore, the distribution could be made simple and random with the given formula:

[tex]np > 10[/tex]

Therefore, for case (a) simple and random distribution would be determined with p  0.10.

[tex]np > 10\\n (0.10) > 10n \\n> 100[/tex]

Now, for case (b) where p is 0.15 for computing simple and random distribution.

[tex]np > 10\\n (0.15) > 10\\n > 66.67[/tex]

Hence, when 7 more samples would be added to the distribution then it would become a simple and random distribution.

In the essay “the impact of the protestant reformation,” there is much discussion of the individual now being able to study scripture for himself or herself. this not only affected their view of the church but also the state. how has this influenced how we in america today view freedom, government, and rights

Answers

The states right perspective favored the rights of individual states over rights claimed by the national government. Hope this helps!

One of the most important legacies that the Protestant Reformation left on society was the encouragement to think individually, and develop a personal system of ethics. This was markedly different from the rhetoric that the Catholic Church had towards religious practices. The Catholic Church focused on traditions, institutions and rituals as opposed to personal interpretation.

The modern state has been significantly affected by the Protestant way of thinking. It has led to the development of individualism. In turn, individualism has allowed for the development of ideas such as private rights, the limits on government and the supremacy of the law. It has also led to the protection of individual rights and freedoms.

Why do we tend to blame others for their misfortunes but deny responsibility for our own?

Answers

We tend to blame others for their misfortune because we try to distance ourselves from thoughts that we might experience the same misfortune. We are driven by our emotional and motivational drives that's why we have attributions. When something went wrong to others, we are triggered to explain why it happened to them. Thus, it results to blaming the victim instead of looking at the context or system.

When we are the one that is responsible with a certain problem, we are triggered to defend ourselves. We are all afraid of failures, so we make attributions explaining why it happened. We blame and judge others to avoid or deny our responsibility to the problem.
