Three statements are given followed by three conclusions numbered I, II and III. 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: All insects are birds. All reptiles are birds. No crab is bird. Conclusions: I. No insect is reptile. II. Some insects are reptile. III. No crab is reptile. Correct Answer Only Conclusion III and either I or II follows. Drawing the Venn diagram, [ alt="F2 S.Y 9.3.20 Pallavi D9" src="//storage.googleapis.com/tb-img/production/20/03/F2_S.Y_9.3.20_Pallavi_D9.png" style="width: 280px; height: 77px;"> Conclusion 1: No insect is reptile → False (It is possible but not definite) Conclusion 2: Some insects are reptile → False (It is possible but not definite) Conclusion 3: No crab is reptile → True Hence, ‘Only conclusion III follows and either I or II follows’ is the correct answer.
