Three statements are followed by four conclusions numbered I, II, III and IV. 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:
I. All parrots are doves,
II. No dove is canary.
III. All flamingoes are canaries.
Conclusions: ​
I. Some flamingoes are parrots. ​
II. No canary is parrot
III. No parrot is flamingo.
IV. Some canaries are parrots. ​

Statements:
I. All parrots are doves,
II. No dove is canary.
III. All flamingoes are canaries.

From the statement following Venn diagram can be-

I. Some flamingoes are parrots:

Since all flamingos are canaries (statement III), and no dove is a canary (statement II), and all parrots are doves (statement I),

there cannot be any flamingos that are parrots. (False)

II. No canary is a parrot:

From statement II, we know that no dove is a canary. Since all parrots are doves,

it follows that no parrot can be a canary.(True)

III. No parrot is a flamingo:

Since all flamingos are canaries, and no dove is a canary, it follows that no parrot,

which is a dove, can be a flamingo.(True)

IV. Some canaries are parrots

From statement II (no dove is a canary) and statement I (all parrots are doves),

we can conclude that no canary can be a parrot.(False)

Thus, correct answer is Only conclusions II and III follow.​
