### Translating English Sentences into Predicate Logic

**Task 3:** Translate the following English sentence into predicate logic (P). Be sure to include your interpretation key.

**Sentence:**  
"If no one is taller than Becky, then Becky is taller than everyone."

#### Suggested Translation and Interpretation Key

**Translation in Predicate Logic:**

Let \( T(x, y) \) mean "x is taller than y".

\[
\neg \exists x (T(x, \text{Becky})) \rightarrow \forall y (T(\text{Becky}, y))
\]

**Interpretation Key:**
- \( T(x, y) \): "x is taller than y"
- \( \neg \exists x (T(x, \text{Becky})) \): "No one is taller than Becky"
- \( \forall y (T(\text{Becky}, y)) \): "Becky is taller than everyone"

This logical formulation effectively captures the original English statement by using predicates to express relationships between individuals' heights.
