| Moonstone in
Vermont : Solution |
|
 |
|
| We know that at least three of the notices
posted contain false information. |
|
| Based on this information we can conclude
that if Acorn Ridge was the trail leading to Granite Pond then
the notices at Acorn Ridge, Frontage Road and Pine Cone Crest
were true; and the ones at Lazy Hollow and Pepper Tree Pass
were false. Therefore, Acorn Ridge was not the trail to the
lake. |
|
| Following this logic, the chart below shows
what can be determined about each of the five trails: |
|
|
|
|
| As you can see, there is only one instance in which
(at least) three notices contain false information. |
|
| Hence, David was able to figure out
that the only possible trail to Granite Pond was Lazy Hollow. |
