An argument is invalid if and only if _____________. (Points : 1)

English

tangare [24]3 years ago

An argument is invalid if and only if all the premises is true and the conclusion is false.

We can test the invalidity of the argument by assuming all the premises are true and seeing whether it is possible for the conclusion to be false. If the conclusion is possible to be false, then, the argument is invalid.

A valid argument, on the other hand, is valid if and only if it is necessary that:
1) if all of the premises are true, then the conclusion is true
2) if all of the premises are true, then the conclusion must be true
3) it is impossible that all the premises are true and the conclusion is false.

C. Suzie, my best friend, is also an amazing athlete.
It is the sentence that does not contain any errors in comma usage.

Usage of commas
1) to separate items in a series
2) to separate coordinating adjectives
3) to separate two independent clauses (compound sentence)
4) to separate the introductory words from the independent clause.
5) to separate nonessential words, phrases, and clauses

* All choices contain an "appositive". An appositive renames the subject.

My best friend is an appositive for Suzie.Thus it is enclosed by commas to separate it from the rest of the sentence.
