Read the given statements and conclusions carefully. Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the statements. Statements: All bats are birds. Some rats are bats. Conclusions: I. Some rats are birds. II. Some birds are bats. III. All rats are bats. Correct Answer Only conclusions I and II follow. The least possible Venn diagram for the given statements is as shown below : [ alt="F1 Savita SSC 5-7-22 D1" src="//storage.googleapis.com/tb-img/production/22/07/F1_Savita_SSC_5-7-22_D1.png" style="width: 160px; height: 90px;"> Conclusions: I. Some rats are birds → True (As Some rats are bats and All bats are birds. so, Some rats are bats is true) II. Some birds are bats → True (As All bats are birds so, Some birds are bats is true) III. All rats are bats → False (As Some rats are bats so, All rats are bats is possible but not definite true.) ∴ Here, Conclusions I and II are true. Hence, the correct answer is "Only conclusions I and II follow".
