Question 1

Determine whether the conclusion below the line is logically correct or incorrect in light of the two premise statements above the line.

All polite people are good.
Some polite people are educated.
Some educated people are good.

Accepted Answer

Correct

Answer

This is a logically correct conclusion. If all polite people are good, and some polite people are also educated, then the subset of polite people who are educated must necessarily also be good. Therefore, it logically follows that some educated people are good, as they are part of the 'polite people' group that is entirely 'good'.

Question 2

Determine whether the conclusion below the line is logically correct or incorrect in light of the two premise statements above the line.

All curious people are willing to learn new skills.
Old people are not ready to learn new skills.
Old people are not curious

Accepted Answer

Correct

Answer

This is a logically correct conclusion. The first premise states that all curious people are willing to learn new skills. The second premise states that old people are not ready to learn new skills. If a characteristic (willingness to learn new skills) is a prerequisite for being curious, and old people lack that characteristic, then old people cannot be curious. The conclusion directly follows from these premises.

Question 3

Determine whether the conclusion below the line is logically correct or incorrect in light of the two premise statements above the line.

All painters are artists.
Some criminals are painters.
Some criminals are artists.

Accepted Answer

Correct

Answer

This is a logically correct conclusion. If all painters are artists, and some criminals are painters, then those specific criminals who are painters must also be artists. Therefore, it logically follows that some criminals are artists, as they belong to the group of painters, which is entirely comprised of artists.

Question 4

Determine whether the conclusion below the line is logically correct or incorrect in light of the two premise statements above the line.

No man is infallible.
A priest is a man.
No priest is infallible

Accepted Answer

Correct

Answer

This is a logically correct conclusion. The first premise states that no man is infallible. The second premise states that a priest is a man. Since priests are a subset of men, and no man possesses the quality of being infallible, it logically follows that no priest can be infallible. The conclusion is a direct and valid deduction from the given premises.

Question 5

Determine whether the conclusion below the line is logically correct or incorrect in light of the two premise statements above the line.

All good people are ready to help others on the account on their own interest.
Egocentric people are not ready to help others on the account of their own interest.
Egocentric people are not good people.

Accepted Answer

Correct

Answer

This is a logically correct conclusion. The first premise establishes that being 'good' implies a readiness to help others. The second premise states that egocentric people lack this readiness to help. Therefore, if egocentric people do not possess a defining characteristic of good people, it logically follows that egocentric people are not good people. The conclusion is a valid deduction.
