### Translating Arguments into Symbolic Form

This exercise involves translating a given argument into symbolic form and determining its validity. You may use a truth table or compare the argument's symbolic form to a standard valid or invalid form to accomplish this.

#### Given Argument

1. If you tell me the time, I'll pick you up at the airport.
2. I pick you up at the airport.
3. Therefore, you told me the time.

#### Translating the Argument

Let:
- \( p \) represent "You tell me the time."
- \( q \) represent "I pick you up at the airport."

In symbolic form, the argument is:
1. \( p \to q \)
2. \( q \)
3. \(\therefore p \)

#### Determining the Validity

Next, we determine whether the argument is valid or invalid by comparing it with standard forms:

- **Valid Argument Form:**
  - Modus Ponens:
    - \( p \to q \)
    - \( p \)
    - \(\therefore q \)
  - Modus Tollens:
    - \( p \to q \)
    - \( \neg q \)
    - \(\therefore \neg p \)

- **Invalid Argument Form:**
  - Affirming the Consequent:
    - \( p \to q \)
    - \( q \)
    - \(\therefore p \) (This is the form presented here.)

#### Conclusion

Select the correct option below:

- \( \ \text{A.} \) The argument is valid. In symbolic form the argument is \( p \to q, q, \therefore p \)
- \( \ \text{B.} \) The argument is invalid. In symbolic form the argument is \( p \to q, q, \therefore p \)

Choose option:
\( \text{B} \)
