More questions
Correct Answer: Only either II or IV, and III follow
Explanation:
No tree is fruit. All fruits are stones.
Since the middle term 'fruits' is distributed twice, the conclusion must be particular.
Since one premise is negative, the conclusion must be negative. So, it follows that
'Some stones are not trees'.
All fruits are stones. All stones are rains.
Clearly, it follows that 'All fruits are rains'. III is the converse of this conclusion and so it holds.
No tree is fruit, All fruits are rains.
As discussed above, the conclusion must be particular negative and should not contain the middle term. So, it follows that 'Some rains are not trees'. However, II and IV involve only the extreme terms and form a complementary pair. Thus, either II or IV follows.
Correct Answer: Only conclusion I follows
Explanation:
Since both the premises are particular, no definite conclusion follows. However, I is the converse of the second premise and thus it holds.
Correct Answer: wind
Explanation:
A hurricane cannot exist without wind. A beach is not essential to a hurricane (choice a). A hurricane is a type of cyclone, which rules out (choice b). Not all hurricanes cause damage (choice c).
Correct Answer: Only conclusion II follows
Explanation:
Whether the national norm is appropriate or not cannot be said. So, I does not follow. However, more number of beds per thousand population are available in the state. So, II follows.
Correct Answer: Only II is implicit
Explanation:
The statement simply mentions that Clinton and Roosevelt were the only two persons who were re-elected as President of America. But this does not imply that they were liked by the public for the same reasons or qualities. So, I is not implicit. However, it is clear that that majority of people adore Clinton. So, II is implicit. Nothing about the reasons of Clinton's victory or the election campaign of Clinton's rivals can be assumed from the given statement. So, III is not implicit.
Correct Answer: Both I and II follow
Explanation:
Since both the premises are universal and one premise is negative, the conclusion must be universal negative. Also, the conclusion should not contain the middle term. So, I follows. However, II is the converse of the second premise and thus it also holds,
Correct Answer: Only assumption II is implicit
Explanation:
II explains the fact given in the statement and so is implicit. Nothing about 'mediocre students' is mentioned in or can be deduced from the given statement. So, I is not implicit.
Correct Answer: Only conclusion I follows
Explanation:
Clearly, I directly follows from the statement while II cannot be deduced from it.
Correct Answer: Both I and II follow
Explanation:
The statement clearly implies that it is easier to say than to do something and what people say is different from what they do. So, both I and II follow.
Correct Answer: Both I and II follow
Explanation:
Both the given conclusions clearly bring out the central theme of the proverb given in the statement. So, both I and II follow.
