Syllogism 30 MCQs
1.
Statements:
1. All teachers are graduates.
2. All graduates are educated.
Conclusions:
I. All teachers are educated.
II. Some teachers are educated.
A. Only Conclusion I follow B. Only Conclusion II follows
C. Both Conclusions I and II follow D. Neither Conclusion I nor II follows
Answer: A. Only Conclusion I follow
Explanation:
Teachers ⊆ Graduates and Graduates ⊆ Educated. Therefore, Teachers ⊆ Educated, so I follows.
But the statements do not establish that any teacher actually exists. Hence, II does not follow.
2.
Statements:
1. All doctors are professionals.
2.Some doctors are athletes.
Conclusions:
I. Some professionals are athletes.
II. Some doctors are professionals.
A. Only Conclusion I follow B. Only Conclusion II follows
C. Both Conclusions I and II follow D. Neither Conclusion I nor II follows
Answer: C. Both follow
Explanation:
The existing doctors mentioned in Statement 2 are athletes. Since all doctors are professionals, those same persons are professionals and athletes. Therefore, I follow. They are all doctors and professionals, so II follows.
3.
Statements:
1.No poets are engineers.
2. All musicians are poets.
Conclusions:
I. No musicians are engineers.
II. Some musicians are engineers.
A. Only Conclusion I follow B. Only Conclusion II follows
C. Both Conclusions I and II follow D. Neither Conclusion I nor II follows
Answer: A. Only Conclusion I follow
Explanation:
Musicians ⊆ Poets, while Poets and Engineers have no common members. Therefore, musicians cannot be engineers. I follow. II directly contradicts this relationship.
4.
Statements:
1.Some artists are writers.
2. All writers are readers.
Conclusions:
I. Some artists are readers.
II. Some readers are artists.
A. Only Conclusion I follow B. Only Conclusion II follows
C. Both Conclusions I and II follow D. Neither Conclusion I nor II follows
Answer: C. Both follow
Explanation:
At least one person is both an artist and a writer. Since every writer is a reader, that person is also a reader. Thus, some artists are readers and, equivalently, some readers are artists.

5.
Statements:
1.Some students are athletes.
2.No athletes are singers.
Conclusions:
I. Some students are not singers.
II. Some athletes are not singers.
A. Only Conclusion I follow B. Only Conclusion II follows
C. Both Conclusions I and II follow D. Neither Conclusion I nor II follows
Answer: C . Both follow
Explanation:
The student-athlete mentioned in Statement 1 exists. No athlete is a singer, so this person is not a singer. Hence, both conclusions follow.
6.
Statements:
1. All pilots are trained.
2.No trained people are careless.
Conclusions:
I. No pilots are careless.
II. No careless people are pilots.
A. Only Conclusion I follow B. Only Conclusion II follows
C. Both Conclusions I and II follow. D. Neither Conclusion I nor II follows
Answer: C. Both follow
Explanation:
Pilots ⊆ Trained and Trained ∩ Careless = ∅. Therefore, Pilots ∩ Careless = ∅. The relationship is reversible for a “No A is B” statement, so both conclusions follow.
7.
Statements:
1.No lawyers are teachers.
2.Some researchers are lawyers.
Conclusions:
I. Some researchers are not teachers.
II. Some lawyers are not teachers.
A, Only Conclusion I follow B. Only Conclusion II follows
C. Both Conclusions I and II follow D. Neither Conclusion I nor II follows
Answer: C. Both follow
Explanation:
Some researchers are lawyers, and no lawyer is a teacher. Therefore, those researchers are not teachers. The same existing persons are lawyers who are not teachers. Both follow.
8.
Statements:
1. All engineers are graduates.
2. Some managers are engineers.
Conclusions:
I. Some managers are graduates.
II. Some managers are not graduating.
A. Only Conclusion I follow B. Only Conclusion II follows
C. Both Conclusions I and II follow D. Neither Conclusion I nor II follows
Answer: A. Only Conclusion I follow
Explanation:
Some managers are engineers, and all engineers are graduates. Therefore, some managers are graduates. There is no basis for saying that any manager is not a graduate.
9.
Statements:
1. Some athletes are not students.
2.All teachers are students.
Conclusions:
I. Some athletes are not teachers.
II. Some athletes are teachers.
A.Only Conclusion I follow B. Only Conclusion II follows
C. Both Conclusions I and II follow D. Neither Conclusion I nor II follows
Answer: A. Only Conclusion I follow
Explanation:
The existing athletes mentioned are not students. Since every teacher is a student, a person who is not a student cannot be a teacher. Therefore, I follow, while II does not.

2.No doctors are trained.
Conclusions:
I. No nurses are doctors.
II. Some nurses are not doctors.
A,. Only conclusion: I follow B. Only Conclusion II follows
C. Both Conclusions I and II follow D. Neither Conclusion I nor II follows
Answer: A. Only Conclusion I follow
Explanation:
Nurses are trained, whereas doctors cannot be trained. Therefore, no person can simultaneously be a nurse and a doctor. However, the existence of nurses is not guaranteed, so II does not follow.
11.

1.All writers are readers.
2.No writers are travelers.
Conclusions:
I. No readers are travelers.
II. Some readers are not travelers.
A. Only Conclusion I follow B. Only Conclusion II follows
C. Both Conclusions I and II follow D. Neither Conclusion I nor II follows
Answer: D. Neither follows
Explanation:
We know writers are readers, and writers are not travelers. But other readers may be travelers. Also, the existence of writers/readers is not necessarily established. Hence,ce neither conclusion follows.

Conclusions:
I. Some singers are not doctors.
II. Some dancers are not doctors.
A. Only Conclusion I follow B. Only Conclusion II follows
C. Both Conclusions I and II follow D. Neither Conclusion I nor II follows
Answer: C Both follow

Conclusions:
I. Some painters are sculptors.
II. All painters are sculptors.
A. Only Conclusion I follow B. Only Conclusion II follows

I. Some employees are not accountants.
II. Some employees are accountants.
A. Only Conclusion I follow B. Only Conclusion II follows
C. Both Conclusions I and II follow D. Neither Conclusion I nor II follows
Answer: A. Only Conclusion I follow

Conclusions:
I. Some workers are not pilots.
II. Some workers are not smokers.
A. Only Conclusion I follow B. Only Conclusion II follows
C. Both Conclusions I and II follow D. Neither Conclusion I nor II follows
Answer: A. Only Conclusion I follow
Explanation:
The existing workers who are smokers cannot be pilots because no pilot is a smoker. Thus, some workers are not pilots. There is no evidence that some workers are non-smokers.
19.
Statements:
1. Some teachers are not writers.
2. Some students are writers.
Conclusions:
I. Some teachers are not students.
II. Some teachers are students.
A. Only Conclusion I follow B. Only Conclusion II follows
C. Both Conclusions I and II follow D. Neither Conclusion I nor II follows
Answer: D. Neither follows
Explanation:
The two “some” groups need not be the same or different. A teacher who is not a writer could be a student, or could be a non-student. Therefore, neither conclusion is certain.

2.All graduates are educated.
Conclusions:
I. Some teachers are not educated.
II. Some teachers are educated.
A.Only Conclusion I follow B. Only Conclusion II follows

Conclusions:
I. No scientists are artists.
II. No artists are scientists.
A. Only Conclusion I follow B. Only Conclusion II follows
C. Both Conclusions I and II follow D. Neither Conclusion I nor II follows
Answer: C. Both follow
Explanation:
Conclusion I is directly stated. “No scientists are artists” means scientists and artists do not overlap; therefore, the reverse form “No artists are scientists” also follows.

Statements:
1.All musicians are artists.
2.No musicians are dancers.
Conclusions:
I. No musicians are dancers.
II. No dancers are musicians.
A. Only Conclusion I follow B. Only Conclusion II follows
C. Both Conclusions I and II follow D. Neither Conclusion I nor II follows

Statements:
1.All doctors are trained.
2.Some nurses are trained.
3.No doctors are nurses.
Conclusions:
I. Some nurses are not doctors.
II. Some nurses are doctors.
A. Only Conclusion I follow B. Only Conclusion II follows
C. Both Conclusions I and II follow D. Neither Conclusion I nor II follows
Answer: A. Only Conclusion I follows
Explanation:
Some nurses are trained. Doctors are a separate group from nurses because no doctor is a nurse. Therefore, those existing nurses are not doctors. II is impossible under Statement 3.
