How to Enjoy Your X, XX, XXX, and XXXX Quiz

Answer: XXXX (or XL)

Forty (XXXX/XL), while only five letters, is the only number in the English language to accomplish this unique feat. With Roman Numerals this is a bit different as you don't need to look too far to find letters in alphabetical sequence. In fact, IV (4), IX (9), and CIII (103) are random examples of this.

Pearl Jam's first CD, entitled "Ten", became a smash hit on the alternative rock scene upon its release in 1991.

French sci-fi author Jules Verne, one of the classics and forerunners of the genre, released "Twenty Thousand Leagues Under the Sea" in 1870. The novel, about a crew on the Nautilus scouring the depths of the sea with Captain Nemo at its helm, has been adapted dozens of times over and is a precursor to a number of science fiction pieces. Verne is also known for his works "Around the World in 80 Days", "Journey to the Center of the Earth", and "From the Earth to the Moon". A league is typically regarded as approximately three miles, but this total amount varies in different countries and systems of measurement.

Released in 2004 and earning nearly $100,000,000 in theaters, "13 Going on 30" starred Jennifer Garner, Mark Ruffalo, and Judy Greer. Garner plays a thirteen year old girl who, upon entering a closet, fast-forwards thirty years into her life (with the help of wishing dust) to discover that she works for a magazine and has a successful life.

The movie, while financially successful, was only moderately well-received by critics though it was quite popular with teen viewers.

The Arrondissements of the city are made for the sake of administration. Although there were originally only twelve of these making up Paris, this expanded to a total of twenty after 1860 at which point Louis-Napoleon Bonaparte redefined the limits within France's capital.

The twenty Arrondissements commence in the center of the city with Louvre and spiral outwards, clockwise, until they reach Menilmontant in the east. There are over three hundred Arrondissements in France.

In the NBA, basketball nets stand at opposing sides of the court. Your typical regulation-made net stands exactly ten feet above the ground, which is slightly more than three meters in height. Of course, measurement is important in a game like basketball. Precision counts as well as distance. Depending on where the ball is thrown, you'll be able to score more points. Since the net is so high up, the taller you are, the more likely you'll be picked first for the sport.

Although modern nets allow the ball to pass through, the original basketball hoop was constructed with a peach basket, so balls needed to be removed by hand.

Answer: XXXX (or XL)

Someone who takes forty winks would be someone taking a short nap; by that estimation, sleeping for a wink would be sleeping a fortieth of the total. :)
Although no origin can be pinpointed, the term 'forty winks' has appeared in literature for centuries (including Shakespeare and Carroll).
A number of idioms and euphemisms apply to 'going to sleep' including 'taking a catnap', 'getting a beauty rest', 'hitting the hay', and the more literal 'getting shuteye'. You could also 'sleep like a log', but logs don't really sleep...do they?

Answer: XX

Icosahedrons are EVERYWHERE, I tell you. Actually, the icosahedron is a lot less common than your common six-sided die though it is the largest of the platonic solids, three-dimensional shapes in which all edges and faces are congruent. Each face of a regular icosahedron is an equilateral triangle. The other platonic solids are the tetrahedron, cube, octahedron, and dodecahedron.
Icosahedrons appear as the largest d20 die used in later, more complex versions of the "Dungeons and Dragons" role-playing game. In addition, icosahedrons are the inner piece of a magic eight ball.

Answer: X

X, which would be ten on the periodic table, represents Neon (Ne), the second of several noble gases (which also include Helium, Argon, Krypton, and Xenon). Neon is used in the production of, most notably, neon signs.
XX, twenty, would refer to Calcium (Ca), an alkaline earth metal found in dairy products necessary for humans to have healthy teeth and bones.
XXX, number thirty, refers to the transition metal Zinc (Zn) which is also important in human biology and which can be mined from the Earth.
XXXX (or XL), or number forty, represents Zirconium (Zr), another transition metal. This element is less useful for humans, but is typically used as an alloy.
