In this syllogism question, two statements link pizzas, pancakes and bread. Treat both statements as true and decide which of the conclusions, if any, logically follow: Statement I: Some pizzas are pancakes. Statement II: All bread are pizzas. Conclusion I: All pancakes are bread. Conclusion II: No bread are pizzas.

Difficulty: Medium

Correct Answer: Neither conclusion I nor conclusion II follows

Explanation:


Introduction / Context:
This is a classic set based reasoning problem. The two statements describe how the sets pizzas, pancakes and bread are related. From this, you must determine whether either of the suggested conclusions is forced to be true. As always, you must ignore real world food knowledge and treat the statements as purely logical descriptions.


Given Data / Assumptions:

  • Statement I: Some pizzas are pancakes.
  • Statement II: All bread are pizzas.
  • Conclusion I: All pancakes are bread.
  • Conclusion II: No bread are pizzas.
  • Some means at least one but not necessarily all.


Concept / Approach:
A statement like some pizzas are pancakes means there is at least one object that belongs to both sets pizzas and pancakes. All bread are pizzas means that the entire set bread is contained inside the set pizzas. To test each conclusion, you should try to draw a Venn diagram or construct simple examples and see whether it is possible for the statements to be true while the conclusion is false. If that is possible, then the conclusion does not logically follow.


Step-by-Step Solution:
Step 1: Interpret statement I: the sets pizzas and pancakes overlap in at least one element. Step 2: Interpret statement II: the set bread lies completely inside the set pizzas. Step 3: Check conclusion I, all pancakes are bread. The statements do not restrict where pancakes can lie except that some of them overlap with pizzas. Pancakes can exist outside bread, outside pizzas, or anywhere else consistent with some pizzas being pancakes. Step 4: Therefore it is possible to draw a picture where some pizzas are pancakes, all bread are pizzas, but many pancakes are not bread. So conclusion I is not forced. Step 5: Check conclusion II, no bread are pizzas. This directly contradicts statement II, which says all bread are pizzas. If all bread are pizzas, it cannot be true that no bread are pizzas. Step 6: Hence conclusion II definitely does not follow and is actually inconsistent with the premises.


Verification / Alternative check:
Take a concrete example. Let pizzas be {p1, p2, p3}, pancakes be {p2, pan1} and bread be {p1}. Statement I holds because p2 is both a pizza and a pancake. Statement II holds because all bread items (p1) are pizzas. However, not all pancakes are bread because pan1 is a pancake that is not bread, so conclusion I fails. Also bread (p1) is a pizza, so conclusion II, which claims no bread are pizzas, is clearly false. This confirms that neither conclusion is logically valid.


Why Other Options Are Wrong:
Option A chooses conclusion I, which is not forced by the premises. Option B chooses conclusion II, which actually contradicts the second statement. Option C says both follow, which is impossible since one conclusion directly clashes with the statements. Option E suggests that exactly one of them must follow, but we have found situations in which both fail while the statements remain true.


Common Pitfalls:
A common mistake is to treat some pizzas are pancakes as if it were all pizzas are pancakes or all pancakes are pizzas. Another error is to overlook direct contradictions between statements and conclusions, as happens with conclusion II. Always rewrite statements carefully, use arrows or Venn diagrams, and test potential counterexamples.


Final Answer:
The correct reasoning shows that neither conclusion I nor conclusion II follows from the given statements.
