Directions: Study the following questions carefully and choose the right answer:
1
Statements :      All folders are books.
                            Some books are files.

Conclusions :      I. All files being folders is a possibility.
                             II. All books being files is a possibility.
» Explain it
E
There is no negative statement. Thus the possibilities exist in I and II. Hence, both the conclusion I and II follow.

Hencee, option E is correct.
2
Statements :      Some girls are young.
                            No young is a woman.

Conclusions :      I. Some women are not girls.
                            II. All women being girls is a possibility.
» Explain it
B
Some girls are young (I) + No young is a women (E) = I + E = O = Some girls are not women.

Hence, conclusion I does not follow. But the possibility in II exists. Thus, conclusion II follows.

Hence, option B is correct.

3
Statements :      Some pizzas are pasta.
                            All pastas are macaronis.
                            Some macaronis are pastries.

Conclusions :      I. All pizzas being macaronis is a possibility.
                             II. All pastas are pizzas.
» Explain it
A
There is no negative statement. So the possibility exists in I. Hence, conclusion I follows.

Again, Some pizzas are pastas – converse – Some pastas are pizzas. Hence, conclusion II does not follow.

Hence, option A is correct.

4
Statements :  Some inks are staplers.
                        No stapler is a marker.
                        All markers are dusters.

Conclusions : I. Some dusters are not staplers.
                       II. All inks being markers is a possibility.
 
» Explain it
A
No stapler is a marker (E) + All markers are dusters (A) = E + A = O* = Some dusters are not staplers. Hence, conclusion I follows.

Again, Some inks are staplers (I) + No stapler is a marker (E) = I + E = O = Some inks are not markers. Thus, the possibility in II does not exist. Hence, conclusion II does not follow.

Hence, option A is correct.

 
5
Statements : Some blue are trains.
                       No blue is a green.
                       All trains are engines.

Conclusions : I. Some trains are not green.
                        II. All blue being engines is a possibility.
» Explain it
E
Some blue are trains (I) + All trains are engine (A) = I + A = I = Some blue are engines So, All blue being engines is a possibility.
Hence, conclusions II follows.

Again, Some blue are trains (I) conversion – Some trains are blue (I) + No blue is a green (E) = I + E = O = Some trains are not greens.
Hence, conclusion I follows.

Hence, option E is correct.
