Erin is twelve years old. For three years, she has been asking her parents for a dog. Her parents have told her that they believe a dog would not be happy in an apartment, but they have given her permission to have a bird. Erin has not yet decided what kind of bird she would like to have.

Given data

• Erin is 12; has asked for a dog for 3 years.
• Parents said a dog would not be happy in an apartment.
• They allowed Erin to have a bird.

Concept/Approach

Infer only what is logically entailed: the living situation referenced is their own.

Step-by-step reasoning
Reason for denying dog = unsuitability of an apartment ⇒ They live in an apartment.No evidence about preference for birds over dogs (A) or Erin's feelings about birds (B) or intent to move (D).

Verification/Alternative

The parents' reasoning is explicitly tied to an apartment environment, indicating their current residence.

Common pitfalls

• Equating permission for a bird with preferring birds.
• Inferring future moving plans without mention.

Final Answer
Erin and her parents live in an apartment.
