Option should be (d)...assertion is wrong but reason is right because the soviet economy is more developed than the rest of the world but except US

**Assertion: The Soviet economy was then more developed than the rest of the world.**

**Reason: The Soviet Union became a great power after the Second World War.**

The assertion that the Soviet economy was more developed than the rest of the world needs to be examined in the context of the Soviet Union's post-World War II growth and emergence as a global power. While the Soviet Union did experience significant economic growth during this period, it is debatable whether it was more developed than the rest of the world. Let's delve into the details to understand this assertion and reason in more depth.

**1. Post-World War II Economic Growth:**

After World War II, the Soviet Union experienced a period of economic growth driven by various factors such as the implementation of central planning, industrialization, and extensive investments in heavy industry. This growth was particularly robust during the 1950s and 1960s, enabling the Soviet Union to rebuild its war-torn economy and become a major global player.

**2. Industrial and Technological Advancements:**

During this period, the Soviet Union made significant advancements in heavy industry, particularly in sectors such as manufacturing, energy production, and defense. The country heavily invested in sectors like steel, coal, oil, and machinery, which contributed to its economic growth. Additionally, the Soviet Union achieved notable milestones in space exploration, becoming the first country to successfully launch a satellite (Sputnik) and send a human (Yuri Gagarin) into space.

**3. Military Power and Influence:**

The Soviet Union's emergence as a great power after World War II was not solely reliant on its economic growth but also on its military power and influence. The Soviet Union possessed a formidable military and was one of the two superpowers in the post-war era, along with the United States. Its military might and geopolitical influence played a crucial role in its status as a global power.

**4. Comparison with Other Economies:**

While the Soviet Union experienced significant economic growth and achieved various milestones, it is important to note that the assertion that its economy was more developed than the rest of the world is not entirely accurate. The United States, for example, emerged from World War II as an economic powerhouse, with a highly developed industrial base, advanced technology, and a thriving consumer culture. Western European countries also experienced rapid economic recovery and growth during this period.

**Conclusion:**

In conclusion, while the Soviet Union did experience considerable economic growth and became a global power after World War II, it is not accurate to assert that its economy was more developed than the rest of the world. The United States and Western European countries also achieved significant economic advancements during this period. It is important to consider multiple factors and compare various economies to gain a comprehensive understanding of the global economic landscape during that time.
