False. The subject of the sentence "Man is not animal" is 'Man'.
True or false: The three elements of any proposition are the subject, the predicate, and the copula.
False. The three elements of any proposition are the subject-term, the predicate-term, and the copula.

In any proposition, the two concepts which we unite by affirming or seperate by denying are the subject and the predicate.

Explain what the predicate-term is.
Predicate-term is the verbal expression of the predicate of a judgment.
What kind of sentences are not propositions?
Questions, commands, exclamations, and greetings are sentences that are not propositions.
Tell what each of the following letters stands for: S= P= C=
S=subject-term P=predicate-term C=copula
Give six examples of sentences that are not propositions.
Six sentences that are not propositions are "Goodbye", "How are you?", "Eat your dinner", "Come on", "Is it raining?", and "Is it hot outside?".
Explain what the subject-term is.
Subject-term is the verbal expression of the subject of a judgment.
Write the subject-term, predicate-term, and copula for the proposition "I am the Son of God".
Subject-term=I Predicate-term=the Son of God Copula=am
Write the subject-term, predicate-term, and copula for the proposition "I am the vine".
Subject-term=I Predicate-term=the vine Copula=am
Write the subject-term, predicate-term, and copula for the proposition "My kingdom is not of this world".
Subject-term=My kingdom Predicate-term=of this world Copula-is
Write the subject-term, predicate-term, and copula for the proposition "Peter is a man".
Subject-term=Peter Predicate-term=a man Copula=is
Write the subject-term, predicate-term, and copula for the proposition "You are the branches".
Subject-term=You Predicate-term=the branches Copula=are
Write the subject-term, predicate-term, and copula for the proposition "two and two are four".
Subject-term=two and two Predicate-term=four Copula=are
What is the best way to change a sentence that is not in logical form into one that is in logical form?
The best way to change a sentence that is not logical form into one that is in logical form is to rework the predicate-copula portion of the proposition so that it has a form of the verb to be and a relative clause.
Explain what the copula is.
The copula is the word in the proposition that connects or relates the subject to the predicate. The copula is some form of the verb 'to be'. The copula is usually expressed by 'is' or 'are'.

Three sentences that are propositions are "Dogs are not human", "Dogs are an animal", "Cats are not human".
How do you determine whether a proposition is in logical form?
To determine whether or not a proposition is in logical form you have to ask "Does this sentence have a subject-term, predicate-term, and a copula that are easily determined?".
