question:
Credit card -- Credit cards have a printed or embossed bank card number complying with the ISO/IEC 7812 numbering standard. The card number's prefix, called the Bank Identification Number, is the sequence of digits at the beginning of the number that determine the bank to which a credit card number belongs. This is the first six digits for MasterCard and Visa cards. The next nine digits are the individual account number, and the final digit is a validity check code.
answer:
is a mastercard the same as a credit card


question:
Grand Slam (tennis) -- In terms of the current four majors, the first to win all four in a single year was Don Budge, who completed the feat in 1938. To date, 17 players have completed a Grand Slam, though only six in the most prestigious singles titles. Of these players, three have won multiple majors: Rod Laver accomplished the feat twice in men's singles; Margaret Court accomplished the feat three times, in two different disciplines -- once in women's singles and twice in mixed doubles; and Esther Vergeer completed a grand slam twice in Women's wheelchair doubles.
answer:
has anyone won all 4 tennis majors in one year


question:
Second World -- The concept of ``Second World'' was a construct of the Cold War and the term is still largely used to describe former communist countries that are between poverty and prosperity, many of which are now capitalist states. Subsequently the actual meaning of the terms ``First World'', ``Second World'' and ``Third World'' changed from being based on political ideology to an economic definition. The three-world theory has been criticized as crude and relatively outdated for its nominal ordering (1; 2; 3) and sociologists have instead used the words ``developed'', ``developing'', and ``underdeveloped'' as replacement terms for global stratification (which in turn have been criticized as displaying a colonialist mindset) --nevertheless, the three-world theory is still popular in contemporary literature and media. This might also cause semantic variation of the term between describing a region's political entities and its people.
answer:

first world third world is there a second world
