At Camp Euclid there was a great playground. Five kids loved to play there - Lisa, Danny, Justin, Jacob, and Jamie. Their last names were Bland, Walker, and Horlick (there were two sets of siblings among the five). Each child had a favorite activity at the playground - slide, tire swing, monkey bars, rings, and a big rock. From the clues below, determine each person’s full name and favorite activity.
*At Camp Euclid, there were three groups for the kids - Marmots for kids 10-12 years old, Chipmunks for 6-9 year olds, and Minnows for 3-5 years old. None of the five children were Minnows. Jacob and the younger Horlick were Chipmunks. Lisa and the two Walkers were Marmots.
*Lisa didn’t spend very much time in the playground, but when she did, she never went on the slide or the tire swing.
*None of the Marmots liked the rock. Danny didn’t either.
*Jamie was only 9, but she was a Marmot anyway so she could be in the same group with her brother.
*The elder Horlick and the two Chipmunks didn’t like the monkey bars. A girl liked the tire swing.
To solve this problem, we need to create a grid and use the given clues to fill in the information. From the clues, we can determine the following:
1. The three groups at Camp Euclid are Marmots, Chipmunks, and Minnows.
2. Jacob and the younger Horlick were Chipmunks.
3. Lisa and the two Walkers were Marmots.
4. No one liked the rock, including the Marmots and Danny.
5. Lisa didn't go on the slide or tire swing.
6. The elder Horlick and the two Chipmunks didn't like the monkey bars.
7. A girl liked the tire swing.
Let's use this information to fill in the grid:
| Favorite Activity | Group |
----------------------------------------
Lisa | | Marmots |
Danny | | |
Justin | | |
Jacob | | |
Jamie | | |
Based on clue 3, we know that Lisa and the two Walkers were Marmots. So we can fill in their group:
| Favorite Activity | Group |
----------------------------------------
Lisa | | Marmots |
Danny | | Marmots |
Justin | | Marmots |
Jacob | | Chipmunks |
Jamie | | Marmots |
----------------------------------------
From clue 4, we can conclude that Danny didn't like the rock:
| Favorite Activity | Group |
----------------------------------------
Lisa | | Marmots |
Danny | | Marmots |
Justin | | Marmots |
Jacob | | Chipmunks |
Jamie | | Marmots |
----------------------------------------
From clue 5, we know that Lisa didn't go on the slide or tire swing. Since a girl liked the tire swing (clue 7), Lisa must have gone on the slide. Therefore, Jamie must be the girl who liked the tire swing:
| Favorite Activity | Group |
----------------------------------------
Lisa | Slide | Marmots |
Danny | | Marmots |
Justin | | Marmots |
Jacob | | Chipmunks |
Jamie | Tire Swing | Marmots |
----------------------------------------
From clue 6, we can determine that the elder Horlick and the two Chipmunks didn't like the monkey bars. Since Jacob is a Chipmunk, the elder Horlick must be his sibling. Therefore, the younger Horlick must be a Marmot, and Lisa must be a Walker.
| Favorite Activity | Group |
--------------------------------------------
Lisa | Slide | Marmots |
Danny | | Marmots |
Justin | | Marmots |
Jacob | | Chipmunks |
Jamie | Tire Swing | Marmots |
--------------------------------------------
Now we can use the remaining information to fill in the missing information. From clue 4, Danny doesn't like the rock, so Justin must like the rock. From clue 6, the elder Horlick and the two Chipmunks don't like the monkey bars, so Lisa, Danny, and Jacob don't like the monkey bars. Therefore, Justin must like the monkey bars, leaving Jacob with the rings as his favorite activity.
| Favorite Activity | Group |
--------------------------------------------
Lisa | Slide | Marmots |
Danny | | Marmots |
Justin | Monkey Bars | Marmots |
Jacob | Rings | Chipmunks |
Jamie | Tire Swing | Marmots |
--------------------------------------------
Finally, we can determine that Danny must like the tire swing since the remaining favorite activity is the big rock.
| Favorite Activity | Group |
--------------------------------------------
Lisa | Slide | Marmots |
Danny | Tire Swing | Marmots |
Justin | Monkey Bars | Marmots |
Jacob | Rings | Chipmunks |
Jamie | Tire Swing | Marmots |
--------------------------------------------
Therefore, the complete solution is:
- Lisa Walker: Slide, Marmots
- Danny Horlick: Tire Swing, Marmots
- Justin Walker: Monkey Bars, Marmots
- Jacob Horlick: Rings, Chipmunks
- Jamie Bland: Tire Swing, Marmots
