D all of the above, but they were just results of flawed strategy.
France after WW1 was so keen on not fighting again (due to great casulties, and the sheer horror of trench war), that it build great defences on it's frontier with Germany (Maginot line), and thought that she is safe behind them.
French army was defensively orientated, and was not prepared for bold manouvers of Blitzkrieg.
Answer:
The correct answer is B.
Explanation:
In 1985, Mikhail Gorbachev was elected as Secretary General of the Communist Party of the Soviet Union, becoming the Soviet leader. Gorbachev found out that the Soviet economy was going through hard times, affected by inefficiency, low productivity, low quality goods, and excessive bureaucracy. He sought to reform the centrally planned economy by adopting some market mechanisms, which he felt would improve efficiency and alleviate some of the worst bottlenecks of the system. Gorbachev deemed this series of reforms <em>perestroika</em>, or "restructuring" in Russian.
Gorbachev felt that in order to better tackle the problems of the country, open discussion of said problems was necessary. To this end, he also pushed forward glasnost ("openness"), which gave more freedom of expression. However, the new openness led to open talk about topics which were formerly considered forbidden or taboo, like nationalism, multiparty elections, or replacing the the socialist system with a capitalist one. Eventually, the ideas of glasnost spread all over the Eastern European socialist bloc, which led to the restoration of capitalism in these countries by the late 1980s - early 1990s. The Soviet Union itself was dissolved on 25 December, 1991.
Given this historical example, <u>while giving more economic freedom and allowing some market mechanisms in a socialist economy could be beneficial, this could be seen as the ruling communist party loosening its power, which could lead to a political movement against the communist government.</u>

Dred Scott decision, formally Dred Scott v. John F.A. Sandford, legal case in which the U.S. Supreme Court on March 6, 1857, ruled (7–2) that a slave (Dred Scott) who had resided in a free state and territory (where slavery was prohibited) was not thereby entitled to his freedom; that African Americans were not and could never be citizens of the United States; and that the Missouri Compromise (1820), which had declared free all territories west of Missouri and north of latitude 36°30′, was unconstitutional. The decision added fuel to the sectional controversy and pushed the country closer to civil war.
