Problem Description:

The task involves identifying nouns in the given list and coloring them according to a specific code. The code is as follows:

Solution:

#### Step 1: Understand the Categories
- Person: Refers to human beings (e.g., doctor, mom).
- Place: Refers to locations (e.g., school, park, Walmart).
- Animal: Refers to living creatures that are not humans (e.g., bird, puppy, spider).

#### Step 2: Analyze Each Word in the List
We will go through each word and determine its category:

1. School - Place
2. Doctor - Person
3. Bird - Animal
4. Mom - Person
5. Pencil - Thing (not a person, place, or animal)
6. Mall - Place
7. Walmart - Place
8. Grapes - Thing (not a person, place, or animal)
9. Puppy - Animal
10. Tree - Thing (not a person, place, or animal)
11. Park - Place
12. Baby - Person
13. Bay - Place
14. Spider - Animal
15. Lake - Place
16. Sock - Thing (not a person, place, or animal)

#### Step 3: Apply the Coloring Code
Using the categories determined above, we can now apply the coloring code:

- Orange: Doctor, Mom, Baby
- Red: School, Mall, Walmart, Park, Bay, Lake
- Yellow: Bird, Puppy, Spider

#### Step 4: Final Answer
Here is the final categorization and coloring:

- Orange (Person): Doctor, Mom, Baby
- Red (Place): School, Mall, Walmart, Park, Bay, Lake
- Yellow (Animal): Bird, Puppy, Spider

Words that do not fit into any of these categories (e.g., Pencil, Grapes, Tree, Sock) should remain uncolored.
