Pages 12 and 13/X-factor
(1) Who brought the X-factor?
The answer is given in the magazine article.
(2) How much X-factor was used?
First take the hint and convert all the weights into the same unit measure:
0.5 kg = 500g and 0.05 kg = 50g or 50g = 0.05 kg.
From this we can see that two amounts are the same.
X-factor cant be used in the same amount as any other ingredient.
Filling in the matrix tells us that 0.5 kg (500g) of X-factor was used.
(3) What did Chris have for lunch?
Clue 2 tells us to cross off beef for Jo. Clue 3 means that we can dismiss
the roll for Mel and clue 4 tells us that Chris didnt have ham. From clue 5
we learn that Jo had white bread, which means Mel must have had brown
leaving Chris with the roll. Back to clue 1, beef is eliminated leaving only
cheese for Chris and beef for Mel. Which means Jo had ham.
So, Chris had a cheese roll for lunch.
(4) Who played the organ at the fabulous do?
If you carefully read all four verses you will discover that there are
three pairings matching Anna, Chrissy and Sue to (1) colour (2) shoes and (3) musical instruments:
COLOUR: Red, blue and yellow,
SHOE STYLE: Heels, flat and boots,
INSTRUMENT: Drums, flute and keyboard.
Then you can deduce...
SHOE STYLE: Anna wore heels (verse 2), Chrissy wore boots (verse 3) and, thus,
by elimination Sue wore flat shoes.
COLOUR: Sue was wearing yellow (verse 2) and Anna wasnt wearing red (verse 3)
so by elimination she was in blue. This leaves Chrissy in red.
INSTRUMENT: Chrissy was in boots so she was on the drums (verse 4) and Sue
was in yellow so she was playing the flute. Which leaves the girl in blue, Anna,
playing the keyboard.

Columbus first sighted the New World (West Indies) in 1492. For information: Columbus reached
South America in 1498. There are two possible explanations for the origins of America as the name
for the New World. (1) It is named after the Florentine explorer and navigator Amerigo Vespucci .
(2) It is named after a Bristol merchant, Richard Amerike, who financed voyages of the explorer
John Cabot, who landed on Newfoundland in 1497.

The customers photos rearranged would spell out the word MIXTEC (this empire flourished in the
highlands of southern Mexico from about 800 AD until 1521 AD and the people were noted for their
use of metal, unlike the Maya).
This activity requires extracting and interpreting data from the itinerary.

does not reach 30° in Cancun, the rainfall is not too high in Belize, the hurricane season is over,

The Data Table
Sorting out this information should result in discovering that six of the players have good ratings
in all the right categories and their initials (Over Sun, Big Nose, Unbeaten, No Fear, Easy Runner
and Curl Head (names taken from historical Maya data) can be rearranged to spell BOUNCE.
Showing the data as a bar graph would illustrate which qualities are shared by most players;
how few can actually score; and so on. Some comparisons could be also shown in a Venn diagram.
Using the data table you can see that Over Sun has a 2 in 6
scoring average whilst Unbeaten has a 3 in 7 (to compare the ratios we could say 7:21
and 9:21 or 1:3 with 1:21/3 ). So Unbeaten is more likely to score. Though there is an argument
to be made that Over Sun has had more shots at goal than Unbeaten.

A die* (dice). 1 to 6 are the number of spots on the different faces of the die, opposites
make 7 because each pair of sides always sum to 7 (1 and 6, 2 and 5, 3 and 4), sums to 21 is
the number of spots found on a die.
* Dice is the plural, the correct term is die. However, dice for the singular is in such common
usage that it is totally acceptable.
Many solutions are possible.
Tom is the robber. Heres why:
Each of the four only makes ONE false statement, so...
If we do this clue first we cant be sure which is the lie. Sue could be the robber (lie) and him not,
or vice versa. We need to read the next clues to find out.
If Willy did it, then his second statement would also be a lie, so the first is TRUE.
Now we know it isnt Willy (nor Jill) her second statement must be a lie (Toms not the robber).
We know its not Jill because she would then be lying twice, so shes lying about herself.
