completion of logic problems

This Posting is restricted to OTA #101746. Nathan, per our agreement, I have paid an additional 10 credits for the completion of the logic problems (previously attached job no. 4328). As discussed, pages 424: Section 8.2/I: #5, 6, 8, 9, 11, 12, 14 & 15; and Section 8.2/II: 2, 3, 5, 6, 8, & 9. Thank you, again.

Determining whether logic statements are true or false.

Explain whether the following is true or false. A. All reasonable arguments are true. B. The claim "If it is raining, the exposed surfaces will be wet" is an argument composed of simple statements.

Symbolizing and proving an argument.

Symbolize and prove argument below: If there is even one objectively valid moral principle(P), then Objectivism is true (O). Further, if it is morally wrong to torture innocent persons for the fun of it (T), then there is at least one objectively valid moral principle. Certainly it is wrong to torture innocent persons for the fun of it and really, the thought of such a thing is really disgusting (D). Therefore Objectivism is true.

symbolize and prove the arguments below

Moral principles are simply a function of human needs and interests (F). If that's true and if some moral principles would meet human needs and interests better than others (B), then there are at least some objectively valid moral principles (P) and Objectivism is true (O). Further, I would argue that some moral principles do meet our needs and interests as humans better than others do; thus there are at least some objectively valid moral principles.
