Multiple Choice

Which, if any, of the following proofs are correct demonstrations of the validity of this argument? $$\begin{array}{l}\frac { ( A \cdot \sim D ) \cdot ( C \vee D ) } { C }\\\text { Proof } 1\\\begin{array} { l l l } \text { (1) } ( A \cdot \sim D ) \cdot ( C \vee D ) & / C & \text { Premise/Condusion } \\\text { (2) } \mathrm { C } \vee \mathrm { D } & & 1 \operatorname { Simp } \\\text { (3) } \sim \mathrm { D } & & 1 \operatorname { Simp } \\\text { (4) C } & & 2,3 \mathrm { DS } \\\text { Proof } 2 & & \\\text { (1) } ( \mathrm { A } \cdot \sim \mathrm { D } ) \cdot ( \mathrm { C } \vee \mathrm { D } ) & / \mathrm { C } & \text { Premise/Condusion } \\\text { (2) } \mathrm { C } \vee \mathrm { D } & & 1 \mathrm { Simp } \\\text { (3) } \mathrm { A } \cdot \sim \mathrm { D } && 1 \mathrm { Simp } \\\text { (4) } \sim \mathrm { D } && 3 \mathrm { Simp } \\\text { (5) C } && 2,4 \mathrm { DS }\end{array}\end{array}$$

Definitions:

Blindsight

A condition in which a person can respond to visual stimuli without consciously perceiving them, typically occurring after damage to the primary visual cortex.

Subliminal Message

A signal or message designed to pass below the normal limits of perception, not consciously perceived but able to influence thoughts or behavior.

Absolute Threshold

The minimum intensity of a stimulus that is required to be consciously detected 50% of the time by a sensory system, essentially the lowest level of detectable sensation.

Unconscious

The part of the mind that contains thoughts, feelings, desires, and memories that are not within our conscious awareness, but influence our behavior.
