"The moon is much larger than it appears to be. This is worth remembering because next time you are looking at the moon you can say in a deep and myterious voice, 'The moon is much larger than it appears to be,' and people will know that you are a wise person who has thought about this a lot."
Even though the moon is much larger than it appears to be, it's still much smaller than the earth actually is--in fact, only about a quarter of the size. A quarter is only one fourth of a dollar, which these days usually isn't enough money to buy anything of great value. The value of something is usually determined and set by the people selling the item or service in question. Asking questions is a good way to find things out. By asking questions of smart people you'll normally get things called answers in response. But more often you'll find that people are liars and are not to be trusted. Liar is what you call someone who tells lies. These are people who will knowingly decieve and confuse you in order to achieve their personal goals. Polititians are a good example of this. While not all could be labeled with such a harsh epithet, most can be called, with great certainty, liars. This shouldn't be held against them because it is their job. People take on jobs because they need money. In exchange for their services, their employers will give them money, proportional to the amount or degree of difficulty intrinsic the job. Money is something that can be exchanged then for other goods and services, the american version of which is measured in dollars. A dollar can then be split into four quarters and so on. If you were to compare the relative value of a quarter with a dollar, it would roughly approximate the difference in size between the earth and the moon.
Hopefully this clears things up.
