Conclusions: I. Some ruse are garnet: False (It is possible but not definite) II. No ruse is a garnet: False (It is possible but not definite) Both form a complementary pair. Hence, Either conclusion I or conclusion II follows. Additional Information for Either-or case: I. The conclusion must be false but the possiblity must be true. II. One Conclusion must be positive and another must be negative so, that it forms a complementary pair. III. There are only two complementary pairs: 'Some + No' and 'All + Some not' IV. Subject and Object must be same in both the conclusions for 'All + Some not' case. |
