A) All frustrated people are drug addicts | B) Frustrated people are whimsical |

C) All drug addicts are artists | D) Some artists may be drug addicts |

A) Only 1 follows | B) Only 2 follows |

C) Either 1 or 2 follows | D) Both 1 and 2 follow |

Explanation:

Since both the premises are universal and one premise is negative, the conclusion must be universal negative. Also, the conclusion should not contain the middle term. So, 1 follows.

However, 2 is the converse of the second premise and thus it also holds.

A) Only either 1 or 4 follows | B) Only either 2 or 4 follows |

C) Only 3 and 4 follow | D) Only 3 and either 2 or 4 follows |

Explanation:

Since each combiantion of premise contain 2 particular premises, no definite conclusion can be drawn. However, 1 and 4 involve the extreme terms of 2nd and 3rd premises and form a complementary pair. Thus either 1 or 4 follows.

A) None follows | B) Only 1 follows |

C) Only 2 follows | D) Only 3 follows |

Explanation:

Since each combination has of premises has 2 particular premises, so no defenite conclusion follows

A) Only 1 follows | B) Only 2 follows |

C) Only 3 follows | D) Both 1 and 2 follow |

Explanation:

All snakes are trees. Some trees are roads.

Since the middle term is not distributed even once in the premises,so no conclusion follows

Some trees are roads. All roads are mountains

Since one primise is particular,the conclusion must be particularand should'nt contain the middle term. So,it follows that 'Some trees are mountains'. 3 is the converse of this statement and so it holds.

All snakes are trees. Some trees are mountains.

Since the middle term is not distributed even once in the preises, so no definite conclusion follows

A) Only 1 follows | B) Only 2 follows |

C) Either 1 or 2 follows | D) Neither 1 nor 2 follows |

Explanation:

Since one premise is negative , the conclusion must be negative. so 2 does not follow and only 1 follows

A) None follows | B) Only 1 follows |

C) Only 2 and 3 follow | D) Only 3 follows |

Explanation:

2 and 3 are the satements involving the extreme terms of the last 2 premises and form a complementary pair. Thus either 2 or 3 follows

A) None follows | B) Only 1 follows |

C) Only 1 and 2 follows | D) All follow |

Explanation:

Some hills are rivers. Some rivers are deserts.

Since both the premises are particular, no defenite conclusion follows.
