Correct option is D
When the statement
'Some plants are carnivorous' is true, the following immediate inferences can be made:
·
(A) 'All plants are carnivorous' is undetermined: True, as the given statement does not provide information about all plants. Hence, we cannot conclude whether this is true or false.
·
(C) 'Some plants are not carnivorous' is undetermined: True, as the statement does not specify whether there are plants that are not carnivorous.
·
(D) 'No plants are carnivorous' is false: True, because the existence of
some carnivorous plants makes this statement incorrect.
Information Booster 1. Statements like "some" and "all" require careful analysis in logical reasoning.
2. "Some" implies at least one but does not exclude the possibility of more.
3. The truth of "some" invalidates the universal negation (e.g., "no").
4. The undetermined status arises when data does not provide full scope (e.g., all or some not).
5. Logical inference relies on the exact wording of the premises and does not assume anything extra.
