Which statement best describes the impact of the integrated circuit?

• A. It spurred modest incremental improvements
• B. It opened new fields in agriculture
• C. It radically altered the semiconductor industry
• D. It had no impact

Answer: (C)

The main idea being tested is how transformative a technology can be for an entire industry. The integrated circuit bundles many transistors onto a single chip, enabling far more computing power in a tiny, inexpensive package. This change didn’t just add a new feature; it unlocked mass production, dramatically lowered costs, reduced power consumption, and opened up whole new product categories—from calculators to personal computers and smartphones. Because of that, the semiconductor field was completely reshaped: new design practices, fabrication processes, and supply chains emerged to support widespread chip manufacturing and innovation.

That’s why this statement fits best: the integrated circuit radically altered the semiconductor industry. It wasn’t a minor improvement or a shift in a different field like agriculture, and it certainly didn’t have no impact.
