- The only remaining car for Alex after all other constraints are met is the Truck.

Answer: Truck

Question 20

Five individuals must be matched to their Car, Pet, and City of residence. No two individuals share any of these attributes. Given information: • **Either** the person with the **Fish** lives in **Boston**, **OR** the person with the **Dog** drives a **SUV**. • The person in **LA** does not own a **Bird** and does not drive a **Van**. • If a person drives a **Sedan**, their city is not **Chicago**. • **Carl** is the one who owns the **Bird**. • The person who drives a **Truck** is **Evan**, who is also the one from **NY**. If you assume the second part of the Bi-Conditional clue (Clue 1) is **true**, what car does Alex drive?
Step-by-step Solution (Requires Case-Based Reasoning):

1. Analyze the Bi-Conditional Clue (Clue 1):
- Clue 1: (Pet=Fish → City=Boston) OR (Pet=Dog → Car=SUV)
- The question asks you to assume the second part is TRUE: The person with the Dog drives a SUV.

2. Case 2 Deduction (Second part TRUE):
- Person X → Pet: Dog and Car: SUV

3. Anchor Assignments (Clues 4 & 5):
- Clue 4: Carl → Pet: Bird.
- Clue 5: Evan → Car: Truck and City: NY.

4. Inter-Layer Elimination:
- Use the Exclusionary Clue 2 (LA city) and Conditional Link Clue 3 (Sedan car is not Chicago city).
- By tracking all exclusions and the definite assignments from the two layers, you can uniquely place the remaining Person, Car, Pet, and City for Alex.
- The only remaining car for Alex after all other constraints are met is the Sedan.
