Answer : A

Explanation

All prawns are eggs (A) – conversion – some eggs are prawns (I). Hence conclusion I follows. No fish is a prawn (E) + all prawns are eggs (A) = E + A = O ∗ = some eggs are not fish. Hence conclusion II does not follow.

Q 3 - Statements:

I. All fouls are goals.

II. No goal is a score.

Conclusions:

I. No foul is a score.

II. At least some goals are fouls.

Answer : E

Explanation

All fouls are goals (A) + no Goal is a score (E) = A + E = E = no foul is a score. Hence conclusion I follows. Again, all fouls are goals (A) – conversion – some goal are fouls (I). Hence conclusion II also follows.

Q 5 - Statements:

I. Some balls are bats.

II. All bats are gloves.

Conclusions:

I. Some ball are gloves.

II. At least some gloves are bat.

Answer : E

Explanation

Some balls are bats (I) + all bats are gloves (A) = I + A = I = some ball are gloves. Hence conclusion I follows. Again all bats are gloves -conversion - some gloves are bat. Hence conclusion II also follows.

Q 6 - Statements:

I. Some biology are zoology.

II. No zoology is a botany.

Conclusions:

I. No biology is a botany.

II. At least some biology are botany.

Answer : C

Explanation

Some biology are zoology (I) + no zoology is a botany (E) = I &plus E = O = some biology are not botany. But conclusion I and II make a complementary pair (I - E). Hence either I or II follows. So option C is the right answer.

II. All pens are covers.

Conclusions:

I. At least some covers are pens.

II. No cover is a paper.

Answer : A

II. No juice is green.

Conclusions:

I. Some juices are fruits.

II. No fruit is green.

Answer : A
