Robert Bosch Objective Reasoning Quiz 1

Answer: Both the conclusions are correct.
Explanation: Each conclusion proves the given statement between singers and judges.

Explanation:
Clearly, the conclusion must be universal negative and should not contain the middle term. So, it follows that 'No orange is cheap'. Since all oranges are yellow in colour, we may substitute 'oranges' with 'yellow-coloured oranges'. Thus, II follows.

Explanation:
Since both the premises are particular, no definite conclusion follows.

Explanation:
Since the first premise is particular, the conclusion must be particular and should not contain the middle term. Thus, only I follow.

Explanation: The statement clearly states that the gym is closed on Sundays, which implies that it is always closed on Sundays. However, there is no information given that suggests people cannot workout on Sundays, so conclusion B is not valid.

Explanation: Both conclusions I and II follow. The statement establishes that all mammals are warm-blooded animals. Conclusion I follows directly from the statement since dogs are mammals. Conclusion II is a generalization based on the statement.

Explanation: Only conclusion I follow. The statement establishes that all roses are flowers. Conclusion I follow since it suggests that some flowers (referring to roses) are indeed roses. However, conclusion II is incorrect since it contradicts the statement by claiming that all flowers are roses, which is not necessarily true.

Explanation: Neither conclusion I nor II follows. The statement states that no reptiles are mammals, meaning there is no overlap between the two categories. Conclusion I contradict the statement by claiming that all mammals are reptiles. Conclusion II is also incorrect as it contradicts the initial statement.

Explanation: Only conclusion II follows. The statement establishes that all whales are mammals. Conclusion I is incorrect since it implies that all mammals are whales, which is not true. Conclusion II is valid as it acknowledges the possibility of some mammals being whales, without making a universal claim.

Explanation: Neither conclusion I nor II follows. The statement states that no elephants are carnivores, implying that there is no overlap between the two categories.
