Which one of the following statements is incorrect?
In the realm of facts and figures, it is often challenging to pinpoint the one statement that stands out as incorrect. However, in this article, we will delve into a few statements and identify the one that does not hold true. Let’s explore these statements and determine which one is the outlier.
Statement 1: The Great Wall of China is the only man-made structure visible from space.
This statement is incorrect. While the Great Wall of China is an impressive architectural marvel, it is not the only man-made structure visible from space. Other structures, such as the Great Pyramids of Giza, the International Space Station, and the satellite dishes of the Atacama Desert, can also be seen from the cosmos. The misconception likely arises from the fact that the Great Wall is one of the most visible and well-known structures on Earth.
Statement 2: The Earth is flat.
This statement is incorrect. The Earth is not flat; it is an oblate spheroid, meaning it is slightly flattened at the poles and bulging at the equator. This shape is a result of the planet’s rotation and gravitational forces. Throughout history, numerous scientific experiments and observations have confirmed the Earth’s spherical shape.
Statement 3: Water boils at 100 degrees Celsius (212 degrees Fahrenheit) at sea level.
This statement is correct. Water boils at 100 degrees Celsius (212 degrees Fahrenheit) at sea level under standard atmospheric pressure. However, this boiling point can vary with altitude and atmospheric pressure.
Statement 4: The speed of light in a vacuum is approximately 299,792 kilometers per second (186,282 miles per second).
This statement is correct. The speed of light in a vacuum is indeed approximately 299,792 kilometers per second (186,282 miles per second). This value is a fundamental constant in physics and has been confirmed through various experiments and observations.
Statement 5: Humans can survive without water for only three days.
This statement is incorrect. While water is essential for human survival, the actual duration a person can survive without water varies. Generally, an adult can survive without water for about three to four days, depending on factors such as temperature, humidity, and physical activity levels. However, some individuals may survive for a shorter or longer period under certain conditions.
In conclusion, among the statements provided, the incorrect one is: “The Great Wall of China is the only man-made structure visible from space.” The other statements are either correct or have varying degrees of accuracy, depending on the context.
