Question 51.

if only conclusion I follows;
if only conclusion II follows;
if either I or II follows;
if neither I nor II follows and
if both I and II follow.

Discuss Question

Answer: Option D. -> if neither I nor II follows and

Conclusion I being an A type proposition, distributes the term 'roots'. Since the term

'roots' is distributed in I without being distributed in any of the premises, so

conclusion I cannot follow. Conclusion II cannot follow as it contains the middle term.

Question 52.

The following questions two statements are given and these statements are followed by two conclusions

numbered I and II. You have to take tfie given two statements to be true even if they seem to be at variance

from commonly known facts. Read the conclusions and then decide which ofthe given conclusions logically

follows from the two given statements, disregarding commonly known facts.

Statements : All men are dogs. ll. All dogs are cats.

Conclusions : I. All men are cats. II. All cats are men.

if only conclusion I follows;
if only conclusion II follows;
if either I or II follows;
if neither I nor II follows and
if both I and II follow.

Discuss Question

Answer: Option A. -> if only conclusion I follows;

Since both the premises are affirmative, the conclusion must be affirmative. However,

conclusion II being an A type proposition, distributes the term 'goats'. Since the term

'goats' is distributed in II without being distributed in any of the premises, so

conclusion II cannot follow. Thus, only I follows.

Question 53.

Statements : I. All men are married II. Some men are educated.

Conclusions : I. Some married are educated. II. Some educated are married.

only conclusion I follows
only conclusion II follows
either I or II follows
neither I nor II follows
both I and II follow

Discuss Question

Answer: Option E. -> both I and II follow

Since one premise is particular, the conclusion must be particular, so both I and II follows

Question 54.

The following questions two statements are given and these statements are followed by two conclusions

numbered I and II. You have to take tfie given two statements to be true even if they seem to be at variance

from commonly known facts. Read the conclusions and then decide which ofthe given conclusions logically

follows from the two given statements, disregarding commonly known facts.

Statements : All bags are cakes.

All lamps are cakes.

Conclusions : I. Some lamps are bags.

II. No lamp is bag.

if only conclusion I follows;
if only conclusion II follows;
if either I or II follows;
if neither I nor II follows and
if both I and II follow.

Discuss Question

Answer: Option D. -> if neither I nor II follows and

Both the premises being A type propositions, the middle term 'cakes forming the

predicate is not distributed in an> of Â£hem.

Since the middle term is not distributed even once in the premises, so no conclusion

follows.

Question 55.

The following questions two statements are given and these statements are followed by two conclusions

numbered I and II. You have to take tfie given two statements to be true even if they seem to be at variance

from commonly known facts. Read the conclusions and then decide which ofthe given conclusions logically

follows from the two given statements, disregarding commonly known facts.

Statements : All tubes are handles.

All cups are handles.

Conclusions : I. All cups are tubes.

II. Some handles are not cups.

if only conclusion I follows;
if only conclusion II follows;
if either I or II follows;
if neither I nor II follows and
if both I and II follow.

Discuss Question

Answer: Option D. -> if neither I nor II follows and

Both the premises are A type propositions. So, in either, the middle term 'handles'

forming the predicate is not distributed.

Since the middle term is not distributed even once in the premises, so no conclusion

follows.

Question 56.

Statements : I. Some fools are intelligent. II. Some intelligent are great.

Conclusions : I Some fools are great. II. All great are intellligent.

only conclusion I follows
only conclusion II follows
either I or II follows
neither I nor II follows
both I and II follow

Discuss Question

Answer: Option D. -> neither I nor II follows

Both the premises are particular, no conclusion follows are the middle term is not distributed even once in the premises.

Question 57.

Statements : I. All cars are tables. II. Some children are tables.

Conclusions : I. Some cars are children. II. Some children are cars.

only conclusion I follows
only conclusion II follows
either I or II follows
neither I nor II follows
both I and II follow

Discuss Question

Answer: Option D. -> neither I nor II follows

The first premise is an A type preposition, so the middle term 'tables' forming the predicate is not distributed.
The II premise is an I type proposition. So, the middle term forming the predicate is not distributed. Since the middle term is not distributed even once in the premises, so no conclusion follows.

Question 58.

Statements :I. No magazine is a cap. II. All caps are cameras.

Conclusions : I. No camera is magazine. II. Some caps are magazines.

only conclusion I follows
only conclusion II follows
either I or II follows
neither I nor II follows
both I and II follow

Discuss Question

Answer: Option D. -> neither I nor II follows

Since one premise is negative, the conclusion must be negative. So II cannot follow. Also the term 'camera' is distributed in I without being distributed in any of the premises. So, conclusion I also does not follows.

Question 59.

Statements : I. Some papers are files. II. Some files are pens

Conclusions : I. Some files are not pens. II. Some pens are papers.
