The correct answer is
Only conclusion (I) follows

Analyzing Syllogism Statements

We analyze the given logical statements to determine the validity of the conclusions.

  • Statement 1: All angry are birds.
  • Statement 2: Some angry are pigs.

Evaluating Conclusions Logic

Let's break down the statements and conclusions using sets:

  • Statement 1 means the set of 'angry' things is a subset of the set of 'birds'.
  • Statement 2 means there is an overlap between the set of 'angry' things and the set of 'pigs'. There exists at least one entity that is both 'angry' and a 'pig'.

Consider the entities that are both 'angry' and 'pigs' (from Statement 2). Since all 'angry' things are 'birds' (from Statement 1), these specific entities must also be 'birds'.

This directly supports Conclusion (I):

  • Conclusion (I): Some birds are pigs. This follows because the 'angry pigs' are necessarily also 'birds'.

Now consider Conclusion (II):

  • Conclusion (II): All pigs are birds. The statements only tell us about the pigs that are also 'angry'. We don't have information about pigs that are *not* 'angry'. Therefore, we cannot conclude that *all* pigs are birds.

Final Deduction

Based on the analysis, only Conclusion (I) logically follows from the given statements.

Therefore, only conclusion (I) follows.
