Statement:
No plate is a spoon.
Some plates are forks.
All forks are knives.
The least possible diagram for the given statements is as follows:
Conclusions:
(i) Some plates are knives is a possibility - False (Some plates are forks and All forks are knives, so some plates are knives is definitely true).
(ii) No spoon is a fork - False (Because No direct relation given between them, so It can be possible not definite).
Here, Neither conclusion I nor II follows.
Hence, the correct answer is "Option 2".

Given Statements:
I. All Z are Y.
II. Some Y are B.

Conclusions:
I. Some B are not Z.
II. Some Y are not Z.
III. Some Z are Y.

Explanation:

Conclusion I:
- From statement I, we know that all Z are Y.
- From statement II, we know that only some Y are B.
- Therefore, it is not possible to definitively conclude that some B are not Z based on the given statements. Conclusion I does not logically follow.

Conclusion II:
- From statement II, we know that some Y are B.
- Since all Z are Y, it is possible that some Y are Z as well.
- Therefore, it is not possible to definitively conclude that some Y are not Z based on the given statements. Conclusion II does not logically follow.

Conclusion III:
- From statement I, we know that all Z are Y.
- Therefore, it logically follows that some Z are Y based on the given statements. Conclusion III logically follows.

Conclusion:
Therefore, only conclusion III follows based on the given statements.

Read the given statements and conclusions carefully. Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the statements.
Statements :
Some jims are nests.
Some nests are beams.
All beams are coaches.
Conclusions :
I. Some coaches are nests.
II. Some beams are jims.
III. No beam is a jim.
IV. Some nests are jims.
  • a)
    Only conclusions I and II follow
  • b)
    Only conclusions II and III follow
  • c)
    Both conclusions I and IV and either conclusion II or III follow
  • d)
    Only conclusions II and IV follow
Correct answer is option 'C'. Can you explain this answer?

Understanding the Statements
The statements provided can be analyzed to determine the relationships between the categories mentioned:
- Some jims are nests.
- Some nests are beams.
- All beams are coaches.
Analyzing the Conclusions
Let’s evaluate each conclusion based on the statements:
Conclusion I: Some coaches are nests.
- Since all beams are coaches and some nests are beams, it follows that some nests must also be coaches. Hence, this conclusion is valid.
Conclusion II: Some beams are jims.
- The statement indicates that some jims are nests and some nests are beams. However, it does not confirm that any beams are jims, so this conclusion cannot be confidently stated as valid. Thus, this conclusion is not necessarily true.
Conclusion III: No beam is a jim.
- The statements do not provide enough information to conclude that no beams are jims. Since some jims are nests and some nests are beams, it is possible (but not guaranteed) that some jims could be beams. Therefore, this conclusion is not valid.
Conclusion IV: Some nests are jims.
- Given that some jims are nests, it logically follows that some nests must be jims. Thus, this conclusion is valid.
Final Assessment
Based on the evaluations:
- Valid Conclusions: I and IV
- Not Valid Conclusions: II and III
Thus, the correct answer is option 'C': Both conclusions I and IV and either conclusion II or III follow.

In the following question below are given some statements followed by some conclusions based on those statements. Taking the given statements to be true even if they seem to be at variance from commonly known facts. Read all the conclusions and then decide which of the given conclusion logically follows the given statements.
Statements:
I. No F is N.
II. All N are L.
Conclusions:
I. All F are L.
II. All N are F.
III. Some L are N.
  • a)
    Only conclusion II follows
  • b)
    Only conclusion III follows
  • c)
    Only conclusion I follows
  • d)
    All conclusion follows
Correct answer is option 'B'. Can you explain this answer?

EduRev CLAT answered
Given Statements:
I. No F is N.
II. All N are L.
The least possible Venn diagram for the given statement is:
Conclusions:
I. All F are L - False (Because, All N are L and no F is N, so those part of N that is L will be definitely not F).
II. All N are F - False (Because, No F is N).
III. Some L are N - True (Because, All N are L so, some L are N is definitely true).
So, Only conclusion III follows.
Hence, the correct answer is "Option 2".

Directions: Each question consists of five statements followed by options consisting of three statements put together in a specific order. Choose the option which indicates a valid argument, that is, where the third statement is a conclusion drawn from the preceding two statements.

Shireen Kapoor answered
Understanding the Statements
To analyze why option 'B' (ACB) is correct, let's break down the statements:
- A: All software companies employ knowledge workers.
- B: Tara Tech employs knowledge workers.
- C: Tara Tech is a software company.
- D: Some software companies employ knowledge workers.
- E: Tara Tech employs only knowledge workers.
Logical Flow of Option B (ACB)
- Premise 1 (A): All software companies employ knowledge workers.
This establishes a general rule about software companies.
- Premise 2 (C): Tara Tech is a software company.
By asserting Tara Tech's identity as a software company, we can apply the general rule from statement A.
- Conclusion (B): Therefore, Tara Tech employs knowledge workers.
This conclusion logically follows from the premises: since Tara Tech is a software company (C), and all software companies employ knowledge workers (A), it must be true that Tara Tech employs knowledge workers (B).
Why Other Options Are Invalid
- Option A (ABC): This concludes that Tara Tech is a software company based on the premise that all software companies employ knowledge workers. This does not logically follow.
- Option C (CDB): The conclusion that some software companies employ knowledge workers is true but does not directly follow from Tara Tech being a software company.
- Option D (ACE): It states that Tara Tech employs only knowledge workers, which cannot be concluded from the given premises.
Conclusion
The correct option is B (ACB) because it follows a clear logical pathway from the premises to the conclusion, making it a valid argument.

Statements:
Some fruits are mangos.
All mangos are guavas.
No guava is a banana.
Conclusions:
I. All guavas are fruits.
II. Some guavas are fruits
  • a)
    If only conclusion I follows.
  • b)
    If only conclusion II follows.
  • c)
    If either conclusion I or conclusion II follows
  • d)
    If both conclusions I and II follows.
Correct answer is option 'B'. Can you explain this answer?

(i)  All pages are markers     --> Universal Affirmative (A - type).
(ii) Some fruits are apples    --> Particular Affirmative (I - type)
(iii)No book is a page         --> Universal Negative (E - type).
(iv) Some books are  not pages --> Particular Negative (O - type).
Some fruits are mangos.
All mangos are guavas.
I + A => I - type of conclusion
"Some fruits are guavas".
Conclusion II is Converse of it.
All mangos are guavas
No guava is a banana.
A + E => E - type of conclusion
"No mango is a banana"
Answer Option B

Three statements are given followed by two conclusions numbered I and II. Assuming the statements to be true, even if they seem to be at variance with commonly known facts, decide which of the conclusions logically follow(s) from the statements.
Statements:
All birds are crows.
Some crows are parrots.
No crow is a pigeon.
Conclusions:
I. No parrot is a pigeon.
II. Some birds are parrots.
  • a)
    Only conclusion I follows
  • b)
    Only conclusion II follows
  • c)
    Neither conclusion I nor II follows
  • d)
    Both conclusions I and II follow
Correct answer is option 'C'. Can you explain this answer?

EduRev CLAT answered
Given Statements:
All birds are crows.
Some crows are parrots.
No crow is a pigeon.
The least possible Venn diagram for the given statement is:
Conclusions:
I. No parrot is a pigeon - False (Because, No definite relation given between parrot and pigeon, so it can be possibly only).
II. Some birds are parrots - False (Because, No definite relation given between birds and parrots, so it can be possibly only).
So, Neither conclusion I nor II follows.
Hence, the correct answer is "Option 3".

Directions: Each question consists of five statements followed by options consisting of three statements put together in a specific order. Choose the option which indicates a valid argument, that is, where the third statement is a conclusion drawn from the preceding two statements.
A. Traffic congestion increases carbon monoxide in the environment.
B. Increase in carbon monoxide is hazardous to health.
C. Traffic congestion is hazardous to health.
D. Some traffic congestion does not cause increased carbon monoxide.
E. Some traffic congestion is not hazardous to health.
  • a)
    CBA
  • b)
    BDE
  • c)
    CDE
  • d)
    BAC
Correct answer is option 'D'. Can you explain this answer?

Anushka joshi answered
Understanding the Argument Structure
To determine the valid argument from the given statements, we need to analyze how the statements link together logically.
Statements Breakdown
- A: Traffic congestion increases carbon monoxide in the environment.
- B: Increase in carbon monoxide is hazardous to health.
- C: Traffic congestion is hazardous to health.
- D: Some traffic congestion does not cause increased carbon monoxide.
- E: Some traffic congestion is not hazardous to health.
Identifying Valid Arguments
We need to find a set of three statements where the third statement logically follows from the first two.
Option D: BDE
- B: Increase in carbon monoxide is hazardous to health.
- D: Some traffic congestion does not cause increased carbon monoxide.
- E: Some traffic congestion is not hazardous to health.
Logical Flow
1. Premise 1 (B): It is established that an increase in carbon monoxide is harmful to health.
2. Premise 2 (D): Some traffic congestion does not result in increased carbon monoxide levels.
3. Conclusion (E): From these premises, we can conclude that some traffic congestion is not hazardous to health since it doesn’t contribute to increased carbon monoxide, which is what poses the health risk.
Why Other Options Fail
- Options A (CBA) and C (CDE) do not establish a logical connection between the statements.
- Option B (BDE) seems valid but does not lead to a direct conclusion regarding traffic congestion and health.
Conclusion
Thus, option D (BDE) provides a coherent argument structure where the conclusion logically stems from the premises.

Read the given statements and conclusions carefully. Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the statements.
Statements: 
I. Some X are M.
II. All W are X.
Conclusions:
I. Some M are not W.
II. No W is M.
III. Some M are not X.
  • a)
    None of the conclusions follow
  • b)
    Only conclusion III follows
  • c)
    Only conclusions II and III follow
  • d)
    All the conclusions follow
Correct answer is option 'A'. Can you explain this answer?

Alok Mehra answered
Understanding the Statements
The statements provided are:
- I. Some X are M.
- II. All W are X.
From these statements, we can analyze the relationships between the groups X, M, and W.
Analyzing the Conclusions
1. Conclusion I: Some M are not W.
- Based on statement II, all W are included in X. However, since only some X are M, it is not guaranteed that any M is W. Thus, it is possible that some M are indeed not W, but we cannot definitively conclude it from the given statements.
2. Conclusion II: No W is M.
- This conclusion suggests that there is no overlap between W and M. However, since some X are M and all W are X, it is possible for some W to also be M. Therefore, we cannot conclude that no W is M.
3. Conclusion III: Some M are not X.
- Since some X are M, it is not possible to conclude that some M are not X. In fact, all M could potentially be included in X. Thus, this conclusion does not logically follow.
Final Evaluation of Conclusions
- All conclusions I, II, and III do not logically follow from the statements provided. Hence, the correct option is:
Answer: a) None of the conclusions follow
This analysis illustrates that although some conclusions may seem plausible, they do not necessarily follow from the relationships defined in the statements.

Read the given statements and conclusions carefully. Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the statements.
Statements:
Some jugs are bottles.
No bottle is a candy.
All spoons are bottles.
Conclusions:
I. Some jugs are spoons.
Il. No spoon is a candy.
Ill. No jug is a spoon.
IV. No jug is a candy.
  • a)
    Either Conclusion I or Ill and II follow.
  • b)
    Only Conclusions Il and III follow.
  • c)
    Only Conclusions I, Il and IV follow.
  • d)
    Either Conclusion I or IV and II follow.
Correct answer is option 'A'. Can you explain this answer?

Statements:
- Some jugs are bottles.
- No bottle is a candy.
- All spoons are bottles.

Conclusions:
I. Some jugs are spoons.
II. No spoon is a candy.
III. No jug is a spoon.
IV. No jug is a candy.

Explanation:
- From the given statements, we know that some jugs are bottles and all spoons are bottles. Therefore, some jugs are spoons (Conclusion I) as there is an overlap between jugs and spoons through the common category of bottles.
- It is given that no bottle is a candy, and since all spoons are bottles, it follows that no spoon is a candy (Conclusion II).
- Since all spoons are bottles and some jugs are bottles, there is a possibility that some jugs are spoons. Therefore, it is not necessarily true that no jug is a spoon (Conclusion III does not necessarily follow).
- There is no direct relationship established between jugs and candies in the given statements, so it cannot be definitively concluded that no jug is a candy (Conclusion IV does not necessarily follow).
Therefore, the correct answer is option 'a) Either Conclusion I or III and II follow.'
