attend a racing event, so he asked his friend to update him on the
results. His friend decided to tease him. Instead of telling him the

some ties  as follows:
Penuche Fudge finished before Near Miss and after Whispered Promises.
Whispered Promises tied with Penuche Fudge if and only if Happy Go Lucky did
not tie with Skipper's Gal.
Penuche Fudge finished as many places after Skipper's Gal as Skipper's Gal
finished after Whispered Promises if and only if Whispered Promises finished
before Near Miss.

The mathematician Charles Lutwidge Dodgson
(better known as Lewis Carroll) is credited with inventing a puzzle he called a
"doublet", between 1879 and 1881. It is also known as a "word
ladder" puzzle.
To solve such a puzzle, you transform a starting word into an ending word (usually
an opposite) by changing one letter at a time, using a real word at every step (in other
words, creating links between words that differ by only one letter, creating a chain).
For example, a FOOL can become WISE
(for solution steps, see box at right [changed letters are in red]).
The object is to complete a chain in the least number of steps (links).
Try your hand at figuring out the steps (links) for these doublets:
