Answer 1

To understand the output of the program, let’s analyze the provided code snippet step by step:

1. The program takes an input from the user, which we are told is `25`.

2. The condition being evaluated is:
```
IF num > 20 AND num < 22
```

3. We need to check if the condition is true when `num` is `25`:
- `num > 20` evaluates to `true` (since 25 is greater than 20).
- `num < 22` evaluates to `false` (since 25 is not less than 22).

4. Since the condition uses the `AND` operator, both parts must be true for the overall condition to be true. In this case, one part is true and the other is false, meaning the overall condition evaluates to `false`.

5. Given that the condition is false, the program will execute the `ELSE` block, which outputs:
```
OUTPUT "Invalid."
```

Therefore, since the user enters `25`, the output of the program will be:

**Invalid.**
