Difficulty: Easy
Correct Answer: It quickly and efficiently separated cotton fibers from their seeds.
Explanation:
Introduction / Context:
The cotton gin is one of the classic inventions mentioned in world history and economics because it changed the way cotton was processed. Before its invention, separating cotton fibers from seeds was very slow and labor intensive. This question focuses on why the cotton gin was such an important invention, emphasizing its practical impact on cotton production rather than who invented it or when it was invented.
Given Data / Assumptions:
Concept / Approach:
Raw cotton harvested from the plant contains many seeds mixed with fluffy fibers. Before the cotton gin, this separation was done by hand and took a lot of time. The cotton gin mechanized the process, allowing large quantities of cotton to be cleaned quickly. This made cotton a far more profitable crop and transformed textile manufacturing. To answer the question correctly, we must choose the option that describes this key function rather than unrelated claims about irrigation, weaving, or ships.
Step-by-Step Solution:
Verification / Alternative check:
History and economics textbooks consistently explain that the cotton gin dramatically sped up the cleaning of cotton by mechanizing the separation of fibers from seeds. This allowed a single machine to do the work that would have required many laborers, which in turn increased cotton production and profitability. None of the other stated effects, such as changing irrigation or ship engines, are associated with the cotton gin in standard references. This makes it clear that the only accurate description of its importance is the one about separating fibers from seeds.
Why Other Options Are Wrong:
Option B talks about weaving cloth faster on traditional looms, but that is related to weaving technology and textile machinery, not the cotton gin. Option C suggests that cotton plants could grow without irrigation, which has nothing to do with a mechanical processing machine. Option D mentions replacing steam engines on ships with electric motors, which is entirely unrelated to cotton processing. These incorrect options are designed to distract you if you do not recall what the cotton gin actually does.
Common Pitfalls:
A common mistake is confusing the cotton gin with other types of textile machines that spin or weave fibers into thread and cloth. Another pitfall is to assume that any important invention must have changed multiple things at once, such as irrigation or transportation, even if that is not historically accurate. To avoid these errors, always link the cotton gin specifically with the step of cleaning raw cotton by removing seeds, and remember that this change alone was enough to make the invention historically significant.
Final Answer:
The cotton gin was important because it quickly and efficiently separated cotton fibers from their seeds.
