DXC Logical Syllogism Quiz -4

Answer: A) Only conclusion I follows.

Explanation:
Conclusion I: Based on statement 1 and 3, we can conclude that no shrub can be a flower. This follows directly from the given statements.
Conclusion II:There is no direct information or relationship given between plants and flowers. Hence, we cannot conclude that some plants are not flowers.

Answer:D) Neither conclusion I nor II follows.

Explanation:
Conclusion I: we know that some birds can swim and all flying creatures have wings. But there is no information about birds flying so we cannot conclude that some birds have wings.
Conclusion II: we know that no fish can fly. However, there is no direct information about whether fish can swim or not. so it is not possible to conclude that some fish can swim.

Answer:C) Both I and II conclusions follow.

Explanation:
Conclusion I: From statements 1 and 2 it is evident that some pens are pencils and all pencils are erasers so in turn there are some pens that are erasers. Therefore, the conclusion I follows.
Conclusion II: we know that no eraser is a marker and all pencils are erasers. Therefore, it is possible that there are markers that are not pens. Hence, Conclusion II follows.

Answer:D) Neither conclusion I nor II follows.

Explanation:
Conclusion I: we know that some animals are cats and all dogs are animals. but, there is no relation specified between cats and dogs so ,conclusion I does not follow.
Conclusion II: we know that no cat is a bird, but some animals are cats. Therefore, it is not possible to conclude that some birds are animals. Hence, Conclusion II does not follow.

Answer: A) Only conclusion I follows

Explanation:
Conclusion I: we know that some students are athletes and all athletes are tall. Therefore, it is possible that some students are tall. Hence, Conclusion I follows.
Conclusion II: we know that no tall person is short. However, there is no direct information about the relationship between students and short people. Therefore, we cannot conclude that no student is short. Conclusion II does not follow.
Therefore, the correct answer is A) Only conclusion I follows.

Answer: E) None of the conclusions follow.

Explanation:
Conclusion I: there is no direct relationship established between plants and birds. Therefore, we cannot conclude that some plants are birds. Conclusion I does not follow.
Conclusion II: it is stated that no tree is a bird, but there is no direct information about the relationship between flowers and birds. Therefore, we cannot conclude that no flower is a bird. Conclusion II does not follow.
Conclusion III: there is no direct relationship established between animals and flowers. Therefore, we cannot conclude that some animals are flowers. Conclusion III does not follow.

Answer: E) Neither conclusion I nor II follows

Explanation:
1. Fruits are not vegetables. Fruits ∩ Vegetables = Ø
2. Fruits are not grains.Fruits ∩ Grains = Ø

Conclusion I: there is no direct connection or intersection provided between the sets of grains and vegetables. Therefore, we cannot conclude that grains are not vegetables. Conclusion I does not follow.
Conclusion II: Since fruits are excluded from being vegetables (from statement 1), there is no possibility that some vegetables might also be fruits. Conclusion II does not follow.

Answer: B) Only conclusion II follows

Explanation:
1. No dogs are cats. Dogs ∩ Cats = Ø
2. No cats are birds. Cats ∩ Birds = Ø

Conclusion I: Since there is no intersection between the sets of birds and dogs (from statement 1), we can conclude that no birds are dogs. Conclusion I does not follows.
Conclusion II: there is no direct connection or intersection provided between the sets of birds and cats. But , we cannot rule out the possibility that some birds are cats. Conclusion II does follow.

Answer: A) True

Explanation:
1. All cars are vehicles. Cars ⊆ Vehicles
2. All vehicles have wheels. Vehicles ⊆ Wheels
If all cars are vehicles and all vehicles have wheels, it logically follows that all cars have wheels. Conclusion I is True.

Answer:C) No conclusion

Explanation:
This conclusion cannot be drawn from the given statements because it contradicts statement 1. Therefore, Conclusion does not follow.
