**1.**

Isaac and Albert were excitedly describing the result of the Third

Annual International Science Fair Extravaganza in Sweden. There were

three contestants, Louis, Rene, and Johannes. Isaac reported that Louis

won the fair, while Rene came in second. Albert, on the other hand,

reported that Johannes won the fair, while Louis came in second.

In

fact, neither Isaac nor Albert had given a correct report of the

results of the science fair. Each of them had given one correct

statement and one false statement. What was the actual placing of the

three contestants?

2. At a family reunion were the following

people: one grandfather, one grandmother, two fathers, two mothers,

four children, three grandchildren, one brother, two sisters, two sons,

two daughters, one father-in-law, one mother-in-law, and one

daughter-in-law. But not as many people attended as it sounds. How many

were there, and who were they?

3. 97 baseball teams participate

in an annual state tournament. The champion is chosen for this

tournament by the usual elimination scheme. That is, the 97 teams are

divided into pairs, and the two teams of each pair play against each

other. The loser of each pair is eliminated, and the remaining teams

are paired up again, etc. How many games must be played to determine a

champion?

4. Your sock drawer contains ten pairs of white socks

and ten pairs of black socks. If you're only allowed to take one sock

from the drawer at a time and you can't see what color sock you're

taking until you've taken it, how many socks do you have to take before

you're guaranteed to have at least one matching pair?

5. A man

is the owner of a winery who recently passed away. In his will, he left

21 barrels (seven of which are filled with wine, seven of which are

half full, and seven of which are empty) to his three sons. However,

the wine and barrels must be split so that each son has the same number

of full barrels, the same number of half-full barrels, and the same

number of empty barrels. Note that there are no measuring devices

handy. How can the barrels and wine be evenly divided?
