Quiz Answer Key and Fun Facts

1. The letter 'e' is the most common letter in the English language.

Answer: True

Approximately 11% of all letters in the English language are 'e'. (This of course varies slightly with the source of the sample of words.) This is the case with not only English, but also with most other European languages.

2. The primary colors of pigment (sometimes called the subtractive primary colors) are red, yellow, and blue.

Answer: False

They are actually cyan, magenta, and yellow, as anyone who has run out of one color of ink in a printer knows. Cyan can be considered a shade of blue, but magenta is definitely a distinct color from red.

3. Zero is both an even number and an odd number.

Answer: False

There is absolutely no truth to this claim. The mathematical definition of an odd number is "a number that can be expressed as 2n+1, where n is an integer". It is obviously impossible to express zero in this way. From a philosophical point of view, it is possible to argue whether or not zero is really a number (the ancient Romans, for example, believed otherwise), but if it is a number, it is definitely an even number. (The number following it, 1, is an odd number, so zero must be even.)

4. There exist three directions such that, by moving in those three directions, it is possible to go anywhere on a two-dimensional surface.

Answer: True

One possibility is north, east, and southwest.

5. In the English language, it is never grammatically correct to start a sentence with "because".

Answer: False

Because the word "because" is often the beginning of a fragment, many people believe that it cannot be used to start a sentence.

6. The North Pole is the only place on Earth from which it is possible to walk 50 miles south, 50 miles east, and 50 miles north, and end up back where you started.

Answer: False

Certainly it is possible to do this from the North Pole. However, it is also possible to do the same from a point a certain distance from the South Pole, if after walking 50 miles south, you make a full circle (or several full circles) around the South Pole by walking 50 miles east.

7. In logic, the converse and inverse of a statement represent different statements, and are not necessarily logically equivalent.

Answer: False

While they nominally represent different statements (the converse of "If X, then Y" is "If Y, then X" while the inverse is "If not X, then not Y"), they can be shown to be logically equivalent.

8. In mathematics, there is only one infinity; performing algebraic operations on it does not make it a different quantity.

Answer: False

While quantities such as "infinity plus 1", "infinity times 2", and even "infinity squared" are still infinity, "2 to the infinity" is an even larger infinity. This fact is known as Cantor's Theorem.

9. There is actually a painting called "Red Square", consisting of a plain red square.

Answer: True

It was part of the Dadaist movement in art, which involved works of art that made little or no sense. Other Dadaist works included a signed urinal.

10. It isn't not untrue that the truth value of the statement "It isn't not untrue that it isn't not false that 2 plus 2 isn't not unequal to 5" doesn't not avoid failing to be false.

Answer: True

There were 17 negatives on that statement.
