Question 3
The Moon has been worshipped by primitive peoples and has inspired humans to create everything from lunar calendars to love sonnets. But what do we really know about it? The most accepted theory about the Moon's origin is that it was formed from the debris of a massive collision with the young Earth about 4.6 billion years ago. A huge body, perhaps the size of Mars, struck the Earth, throwing out an immense amount of debris that coalesced and cooled in orbit around the Earth. The development of Earth is inextricably linked to the Moon; the Moon's gravitational influence upon the Earth is the primary cause of ocean tides. In fact, the Moon has more than twice the effect on the tides than the Sun. The Moon makes one rotation and completes a revolution around the Earth every 27 days, 7 hours, and 43 minutes. This synchronous rotation is caused by an uneven distribution of mass in the Moon (essentially, it is heavier on one side than the other) and has allowed the Earth's gravity to keep one side of the Moon permanently facing Earth. The average distance from Earth to the Moon is about 384,403 km. The Moon has no atmosphere; without it, the Moon has no protection from meteorite impacts, resulting in a surface covered with impact craters, both large and small. The Moon also has no active tectonic or volcanic activity, so the erosive effects of atmospheric weathering, tectonic shifts, and volcanic upheavals that tend to erase and reform the Earth's surface features are not at work on the Moon. In fact, even tiny surface features, such as the footprint left by an astronaut in the lunar soil, are likely to last for millions of years unless obliterated by a chance meteorite strike. The surface gravity of the Moon is about one-sixth that of Earth's. Therefore, a person weighing 82 kilograms on Earth would only weigh 14 kilograms on the Moon. The geographical features of the Earth most similar to those of the Moon are places such as the Hawaiian volcanic craters and the huge meteor crater in Arizona. However, the climate of the Moon is very different from either Hawaii or Arizona; in fact, the temperature on the Moon ranges from 123 degrees Celsius to -233 degrees Celsius.
In the provided text, the word 'massive' in line 4 is closest in meaning to
Rationale
Huge
In the context of the provided text, 'massive' refers to something of very large size or extent, which aligns closely with the meaning of 'huge.'
A) Dense
The term 'dense' describes the compactness or thickness of a substance, rather than its size. While a dense object can be large, 'massive' in this context specifically emphasizes size rather than how closely packed a material is.
B) Impressive
'Impressive' pertains to something that evokes admiration or respect, typically due to its grandeur or significance. Although a massive object may be impressive, the word 'massive' in the text is focused on physical size rather than the emotional response it might elicit.
D) Unavoidable
'Unavoidable' means something that cannot be avoided or prevented, which is unrelated to the size or dimensions of an object. The use of 'massive' in the text does not convey anything about necessity or inevitability, making this choice incorrect.
Conclusion
The word 'massive' in the context of the passage clearly conveys the idea of significant size, which directly correlates with the meaning of 'huge.' The other options either misinterpret the context or address unrelated aspects of physical characteristics. Thus, in this instance, 'huge' serves as the most accurate synonym for 'massive.'
