Question

Directions: In the question below is a statement followed by two conclusions numbered I and II. You have to assume everything in the statement to be true, then consider the two conclusions together and decide which of them logically follows beyond a reasonable doubt from the information given in the statement.

Statement:  Only science students are permitted to attend the conference, other than science students no one is permitted.

Conclusions: 

I. All students present at the conference are science students.

II. Those students who do not have a science background are not allowed in the conference.

• A. If only conclusion I follows
• B. If only conclusion II follows
• C. If neither I nor II follows
• D. If both I and II follow

Answer 1

Answer:

D. If both I and II follow

Solution: From the statement, we can see that only science students are permitted to attend the conference. So, obviously, all the students present are of science background and also students who are not from science will not be permitted. Therefore, both conclusions I and II follow.
