Getting the Score Trivia Quiz

Answer: Optometrist

An optometrist is one of three professions specializing in eye care, along with opticians and ophthalmologists. The phrase '20/20' refers to someone who has normal vision at a distance of 20 feet. It is sometimes (inaccurately) referred to as perfect vision. The phrase '20/20 hindsight' refers to one who sees everything clearly after the event - most of us have it!

Dentists care for teeth, gynaecologists deal with the female reproductive system, and oncologists treat patients with cancer.

Answer: Cricket

Cricket's newest variant, in which each team gets a measly 20 overs in which to score their runs, produces a fast-paced game that apparently makes better television and appeals to a wider audience than does the traditional 5-day Test Match form of the game, or even the One Day International (50 over) form developed in the 1970s.

The first T20 Cup, as it is also called, was won by India in 2007, the second by Pakistan in 2009, and the third by England in 2010.

Answer: Calcium

Calcium plays several important roles in living organisms. Calcium ion movement acts as a trigger for a number of cellular processes, and calcium is one of the major materials used to produce bones and shells. A diet high in calcium is considered important to help people maintain strong bones.

There are many dietary sources of calcium, including the traditional milk and cheese. For those who are lactose-intolerant, alternatives include almonds, sesame seeds, oranges, figs, broccoli, and a number of other related greens. Vitamin D is also necessary to optimize calcium absorption from food.

Answer: A five-year-old

The deciduous teeth that appear in children usually start erupting around the age of 6 months, and continue to appear until somewhere between two and three years of age, at which time the child will have 20 teeth. Around the age of 6 years these teeth usually start to be replaced by permanent teeth, and an additional 8 teeth usually appear by the age of around 13 years.

The last four teeth of permanent adult dentition are often referred to as wisdom teeth because they appear at a significantly later age (if at all), usually between the ages of 17 and 21.

Answer: Icosahedron

A cube (also called a hexahedron) has 6 squares for its faces, a tetrahedron has 4 triangles, a dodecahedron has 12 pentagons, and an icosahedron has 20 triangles. Along with the octahedron, which has 8 triangles for its faces, these are the Platonic solids - the only polyhedra that can be made using congruent polygons (which means that all of their faces are the same as each other).

The name of the icosahedron may not be familiar, but the object probably is. A Magic 8-ball (which you may remember from childhood, or perhaps from watching "The Simpsons") has a regular icosahedron inside it, with a different possible answer for yes-no questions written on each face. The game of Scattergories uses an icosahedron with a different letter of the alphabet written on each face (traditionally with no Q, U, V, X, Y or Z).

Answer: Twenty questions

In the game of 20 questions, one person selects a target object, and the other players can ask up to 20 yes-no questions to determine what the object is. Usually a few precise starting questions are asked first, such as "Animal, vegetable or mineral?" (or "Animal, thing or person?") and "What color or colors are you?", in order to create a realistic goal. Mathematical game strategy says that each question should be designed to eliminate half of the remaining possibilities, as 20 such questions would lead to a single one out of over a million starting possibilities being identified.

But it takes a while to develop such restraint, and not just guess hunches!

Answer: 20 = 2 x 2 x 5

Squaring a number means multiplying it by itself, so 2 x 2, 3 x 3, 4 x 4 and 10 x 10 are ways of showing a squared number.

A prime number is a number larger than 1 which has only itself and 1 as factors; the first five prime numbers are 2, 3, 5, 7 and 11. Only 3x3 and 2x2 are squares of prime numbers. The equations involving 10 x 10 and 4 x 4 are thus eliminated.

The product of two numbers is the answer obtained when the two numbers are multiplied together. Thus, only 20 = 2 x 2 x 5 is a representation of the statement in the question.

20 = 3 x 3 + 11 represents the statement that 20 is the sum of a prime number and a squared prime, as a sum is obtained when numbers are added.

Answer: XX

In Roman numerals, letters are used to stand for numbers, and the value of the number represented is found by adding (or subtracting, but that's another quiz) the values shown by the symbols. The letter I stands for 1, so II represents the number 2. V stands for 5, but VV is not used to show 10 - that is X (which, it has been suggested, originated by placing the two V symbols on top of each other instead of side by side), and XX is 20. C stands for 100, so CC represents 200; M is 1,000 and MM is 2,000.

Answer: Frank Robinson

These were all great baseball players, but the other three were not African-American, and had finished their careers before Robinson started his.

Frank Robinson was also the only player in the 20th century to win the League Most Valuable Player award for both the National League (in 1961 with Cincinnati) and the American League (in 1966 with Baltimore). In 1966, Robinson's first year in Baltimore, he won the American League Triple Crown, with a batting average of 0.316, 49 home runs and 122 runs batted in.

Answer: Egypt

The Valley of the Kings, near Luxor in northern Egypt, is the site of the tombs of many pharaohs, including Tutankhamun and Ramses the Great.

The country code for France is 33; China is 86 and India is 91.
