The answer of Some non-A are not B. (T) Some...

Question 2

Some non-A are B. (F) Contradiction

Accepted Answer

According to the statement given, it is a contradiction that some non-A are B. This means that no non-A can be B. Therefore, option E "No non-A are B" is true.

Question 3

Categorical Proposition 1C
Given the categorical proposition:
"Some corporations that are operating in the United States are not enterprises that are earning a profit."

-In Categorical Proposition 1C, the quantity is:

Accepted Answer

The proposition is a particular proposition because it refers to only some corporations, not all. Specifically, it refers to corporations that are operating in the United States but are not earning a profit.

Question 4

Some non-A are not B. (F) Subcontrary

Accepted Answer

The statement "Some non-A are not B" is equivalent to "It is not true that all non-A are B". From the subcontrary relationship, we know that if "It is not true that all non-A are B" is true, then "Some non-A are B" must also be true. Therefore, choice B is the best option. Choices A, C, D, and E cannot be determined to be true or false based on the given statement.

Question 5

Given the categorical proposition "Some franchises are moneymakers." If both the quality and the quantity are changed, the resulting proposition is:

Accepted Answer

Changing both the quality and the quantity of the original proposition "Some franchises are moneymakers" results in "No franchises are moneymakers." This changes the quantity from "some" to "no" and the quality from affirmative to negative.

Given the categorical proposition:
"Some corporations that are operating in the United States are not enterprises that are earning a profit."

-In Categorical Proposition 1C:

Accepted Answer

In a categorical proposition of form 1C (which typically refers to the universal negative form, "No S are P"), the subject term is distributed because it refers to all members of the subject class, and the predicate term is also distributed because it excludes all members of the predicate class from being members of the subject class.

Question 11

Given the categorical proposition "All banks are lending institutions." If the quantity but not the quality is changed, the resulting proposition is:

Accepted Answer

Changing the quantity but not the quality of the proposition results in a proposition that is a particular affirmative statement, meaning it applies to some, but not all, members of the subject class. Therefore, the correct choice is A, which reads "Some banks are lending institutions."

Question 12

Given the categorical proposition "Some drugs are not effective medicines." If the quality but not the quantity is changed, the resulting proposition is:

Accepted Answer

To convert the original proposition from "Some drugs are not effective medicines" to the quality-changed proposition, we simply change the predicate from "not effective medicines" to "effective medicines." This gives us "Some drugs are effective medicines." Therefore, the correct choice is E.
