Education can play a fundamental role in reducing poverty, but high-quality and up-to-date textbooks are often too expensive for most people in developing countries, reports ScienceDaily. To make education more accessible, a professor in the University of Georgia Terry College of Business is spearheading an effort to produce free online textbooks using a modified version of the Wiki software that powers the Web site Wikipedia.

Through what he’s dubbed, “The Global Text Project,” Watson and an international team of professors aim to create a free library of 1,000 electronic textbooks covering subjects typically encountered during the first two years of college. A prototype text is already complete, and work is underway on the first book in the series.

Puzzle 1 : The land of Numeria everyone is either a Truth-Teller, who always tells the truth, or a Liar, who never tells the truth. One of their favorite activities is playing the game of Number War. Each player starts the game with 9 cards in his hand, numbered from 1 to 9. The game is played in 9 rounds. On each round each player places one of his (remaining) cards face down in front of him. After all players do so the cards are all turned face up and the player having the highest card wins all of the cards in play, which he collects and keeps in a stockpile in front of him. If there were 2 or more cards tied for highest then each player (not just the tied ones) wins (only) the card he played and puts it in his stockpile. Then the next round begins. After all 9 rounds all of the cards will have been won by someone. Then each player calculates the sum of all of the cards in his stockpile and this is his score. The highest score wins.

Four residents of Numeria (whose names I will abbreviate by using only the first letter) played a game of Number War and then made the following statements:

A1: I won exactly 3 rounds.

A2: My score was over 100.

A3: There were exactly 2 tied rounds.

A4: At least 2 players won the same number of rounds.

B1: I won exactly 1 round.

B2: My score was over 47.

B3: There were exactly 3 tied rounds.

B4: None of the scores are divisible by the square of a prime.

C1: I did not win any rounds.

C2: My score was greater than 12.

C3: The winner won less than 3 rounds.

C4: 4 different cards were played on every winning round.

D1: I won exactly 2 rounds.

D2: My score was less then 14.

D3: There was exactly 1 tied round.

D4: The winning score was less than 63.

What was each player’s score?
