Fido and Spot are dogs. Assume whenever it is hot, Fido and Spot are lazy and quiet. Based on this assumption, which statement must be true?
If Spot is lazy but Fido is not quiet, it is not hot.
If it is hot, Fido is lazy and Spot is quiet.
If it is not hot, Fido and Spot are neither lazy nor quiet.
If Fido is quiet or Spot is lazy, it is hot.
The Correct Answer is A
A. If Spot is lazy but Fido is not quiet, it is not hot: This must be true. According to the assumption, when it is hot, both Fido and Spot are lazy and quiet. If Spot is lazy but Fido is not quiet, then it contradicts the assumption that both dogs should be lazy and quiet when it's hot. Therefore, it must not be hot.
B. If it is hot, Fido is lazy and Spot is quiet: This is incorrect because the assumption says both Fido and Spot are lazy and quiet when it's hot, but this statement only mentions Fido being lazy and Spot being quiet. The assumption requires both dogs to be both lazy and quiet, not just one characteristic for each dog.
C. If it is not hot, Fido and Spot are neither lazy nor quiet: This is not necessarily true. The assumption only applies when it is hot, and it doesn’t provide information about Fido and Spot’s behavior when it’s not hot. They could still be lazy or quiet, but it isn’t guaranteed.
D. If Fido is quiet or Spot is lazy, it is hot: This is incorrect. The assumption only states that when it is hot, both dogs are lazy and quiet. It does not claim that if one dog is quiet or lazy, it must be hot. Other circumstances could make Fido quiet or Spot lazy regardless of the temperature.

Correct Answer is B
Explanation
A. may not get well unless he sees a doctor: This is not necessarily true. The original statement only says that sick people should see a doctor, but it doesn't claim that they must see a doctor in order to get well. There might be other ways for him to recover.
B. should see a doctor: This is the best conclusion. The original statement clearly asserts that all sick people should see a doctor, and since the elderly man is ill, it follows that he should see a doctor.
C. should see a doctor if he does not get well: This introduces an unnecessary condition. The original statement does not make recovery contingent on seeing a doctor; it simply says that sick people should see a doctor, regardless of whether they get well on their own.
D. is like most ill people: This is not supported by the statement. The original statement applies specifically to all sick people, not just "most." It does not imply any particular comparison to other ill people.
Correct Answer is B
Explanation
A. Exceptional students are neither humble nor lazy: Based on the first statement, exceptional students are not lazy, and according to the second statement, they must be humble (since they are not arrogant). So, this statement contradicts both premises.
B. Every exceptional student is humble and not lazy: From the first statement, we know that exceptional students are not lazy, and from the second statement, we know that they are humble (since they are not arrogant). Therefore, every exceptional student is humble and not lazy.
C. If someone is an exceptional student, that student is lazy but humble: The statement about exceptional students being "lazy" contradicts the first premise, which specifically says that exceptional students are not lazy.
D. No humble students are lazy: While this might be true in some cases, it is not a conclusion that directly follows from the premises provided. The premises do not state anything about humble students in general being lazy or not.
