Show answer & explanation
Correct answer: C
Explanation
Given Statements:
• Some chicks are chalks. (I)
• Some chalks are chokers. (I)
Evaluation of Conclusions:
• (A) Some chokers are chicks: Two Particular (I + I) premises yield no definite conclusion between 'chokers' and 'chicks'. Hence, it does not follow.
• (B) All chalks are chicks: From the premise 'Some chicks are chalks', we cannot conclude 'All chalks are chicks'. Hence, it does not follow.
• (C) Some chokers are chalks: By the rule of simple conversion of an I-type proposition (Some A are B ⇒ Some B are A), the statement 'Some chalks are chokers' directly implies 'Some chokers are chalks'. Hence, it definitely follows.
Therefore, the correct conclusion is Some chokers are chalks.
