Revelian Test Deductive Reasoning 1

Question 1

All managers are employees. Some employees are remote workers. Which conclusion must be true?

Accepted Answer

Some managers may be remote workers

Answer

Since only 'some' employees are remote workers, managers (a subset of employees) may or may not be among those remote workers, making it possible but not certain.

Question 2

If it rains, the ground gets wet. The ground is wet. What can we conclude?

Accepted Answer

It might have rained, or something else caused it

Answer

A wet ground is consistent with rain but could have other causes; we cannot confirm rain was the reason from the wet ground alone.

Question 3

No birds are mammals. All penguins are birds. Which statement must be true?

Accepted Answer

No penguins are mammals

Answer

Since all penguins are birds and no birds are mammals, it follows necessarily that no penguins are mammals.

Question 4

Every team that trains daily wins competitions. Team A does not win competitions. What can be deduced?

Accepted Answer

Team A does not train daily

Answer

By contrapositive logic, if not winning implies not training daily, then Team A does not train daily.

Question 5

Some students passed the exam. All students who passed the exam received a certificate. Which must be true?

Accepted Answer

Some students received a certificate

Since some students passed and all who passed got certificates, at least those students received certificates, making 'some students received a certificate' necessarily true.
