Write 'T' for True and 'F' for False.
p unless q means `~| q implies p`.

Answer

To determine the truth value of the statement "P unless Q means `~Q implies P`", we will analyze the statement step by step.

### Step-by-Step Solution:

1. **Understanding "P unless Q":**
- The phrase "P unless Q" can be interpreted in logical terms. It means that P is true if Q is not true. In other words, if Q is false, then P must be true.

2. **Rewriting the Statement:**
- The phrase "P unless Q" can be rewritten using logical implications. It can be expressed as "If not Q, then P". This is equivalent to saying that if Q is false, then P must be true.

3. **Symbolic Representation:**
- In symbolic logic, "P unless Q" can be represented as:
\[ \neg Q \implies P \]
- Here, \(\neg Q\) represents "not Q", and the implication (\(\implies\)) indicates that if \(\neg Q\) is true, then P must also be true.

4. **Comparing with the Given Statement:**
- The statement we need to verify is that "P unless Q means `~Q implies P`". We have rewritten "P unless Q" as \(\neg Q \implies P\).

5. **Conclusion:**
- Since our analysis shows that "P unless Q" is indeed equivalent to \(\neg Q \implies P\), we conclude that the statement is true.

Thus, the truth value of the statement "P unless Q means `~Q implies P`" is **T (True)**.
