Question: Which of the following are necessary properties of a sound argument? (select all that apply)

Option 1: Logical strength
- In logic, the term 'logical strength' is typically used to describe how strongly premises support the conclusion, often in the context of inductive arguments. A sound argument, by contrast, is defined specifically as a valid deductive argument with true premises. Therefore, 'logical strength' is not a required property for soundness; a sound argument must be valid, but its strength adjective does not apply in the standard definition of soundness. This option is not a necessary property of a sound argument.

Option 2: None
- Saying there are no necessary properties would be incorrect because soundness requires two things: validity and true premises. Since those two are indeed required, 'None' cannot be correct. This option is not a necessary property of a sound argument.

Option 3: True premises
- For an argument to be sound, the premises must be true. If the premises were false, the argument could still be valid, but it would not be sound. Hence, 'true premises' is a necessary property of a sound argument. This option is a correct property.

Option 4: Deductive validity
- A sound argument must be deductively valid, meaning the conclusion follows logically from the premises with no possible counterexample if the premises are true. Without validity, an argument cannot be sound. Thus, 'deductive validity' is a necessary property of a sound argument. This option is a correct property.

In summary, the concept of soundness requires both true premises and deductive validity; 'logical strength' does not belong to the standard definition, and 'None' is incorrect because there are indeed necessary properties. The two correct properties are True premises and Deductive validity.
