Question

Difficulty: EasySufficient Assumption

Complete the statement with the appropriate word or phrase to make the argument's conclusion follow logically.

Answer:Premise: Any employee who completes the advanced data analysis workshop is eligible for promotion to senior analyst.
Conclusion: Therefore, Marcus is eligible for promotion to senior analyst.

The conclusion follows logically if it is assumed that Marcus 【completed】 the advanced data analysis workshop.

Answer

completed (or has completed)
The premise establishes a universal conditional relationship: completing the advanced data analysis workshop guarantees eligibility for promotion. To deductively prove that Marcus is eligible for promotion, we must establish that Marcus meets the trigger condition. Therefore, assuming that Marcus completed the workshop logically guarantees the truth of the conclusion.

Step-by-Step Solution

1
Identify the stated premise and the conclusion
Premise: Completes workshop implies eligible for promotion. Conclusion: Marcus is eligible for promotion.
Deconstructing the argument isolates the sufficient condition and the necessary outcome.
2
Identify the missing logical bridge needed to guarantee the conclusion
The argument requires establishing that Marcus satisfies the sufficient condition (completing the workshop).
Under Modus Ponens, if the conditional statement 'If P, then Q' is true, establishing P guarantees Q.
3
Fill in the blank with the required condition
Assuming Marcus 'completed' (or 'has completed') the workshop guarantees the conclusion with 100% deductive certainty.
Connecting Marcus directly to the sufficient condition closes the inferential gap completely.
