No glonks are fleeps. All zinks are fleeps. Therefore, some glonks are zinks. If the first two statements are true, the third statement is:
- true
- The conclusion is irrelevant.
- uncertain
- false (correct answer)
Explanation: When you encounter logical reasoning questions with made-up terms, focus on the relationships between the categories rather than getting distracted by the unfamiliar words. This question tests syllogistic reasoning - drawing conclusions from given premises. Let's map out what we know: "No glonks are fleeps" means these two groups have zero overlap - they're completely separate. "All zinks are fleeps" means every single zink belongs to the fleep category. Now, if glonks and fleeps don't overlap at all, and zinks are entirely within the fleep group, then glonks and zinks also cannot overlap. Therefore, the conclusion "some glonks are zinks" is impossible. Choice D is correct because the third statement directly contradicts what must be true based on the premises. If no glonks can be fleeps, and all zinks must be fleeps, then no glonks can be zinks either. Choice A is wrong because we can definitively determine the truth value from the given information. Choice B misses the point - the conclusion isn't irrelevant; it's a logical consequence we can evaluate. Choice C suggests we can't know for certain, but the premises give us enough information to reach a definitive conclusion. Think of these logic problems like Venn diagrams: draw circles representing each group and their relationships. When you see "no" statements, the circles don't touch. When you see "all" statements, one circle sits entirely inside another. This visual approach helps you quickly spot valid and invalid conclusions.
