All managers are employees. All employees are workers. Which of the following conclusions necessarily follows?
Correct: A
From the two universal affirmative premises (All M are E and All E are W), we can chain the relationship: All M are E and All E are W, therefore All M are W. This is a valid syllogism in the first figure (AAA-1). The conclusion 'All managers are workers' follows necessarily. The other options either reverse the relationship or make negative claims not supported by the premises.
