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: Some vehicles are trucks. Some vehicles are lorries. Some trucks are buses. Conclusions: (I) Some vehicles are buses. (II) Some trucks are lorries.
Neither conclusion (I) nor (II) follows.
From the statements, the buses overlap only with trucks (Some trucks are buses); there is no statement directly linking buses to vehicles. The trucks that are buses need not be among the vehicles that are trucks, so it is possible that no vehicle is a bus. Hence conclusion (I) does not necessarily follow.
For conclusion (II), trucks and lorries are each connected only through the common term "vehicles" by two separate "Some" statements. Two particular statements sharing a middle term give no definite link, so the trucks and lorries may be entirely different groups. Hence conclusion (II) does not necessarily follow.
Since neither conclusion is forced by the statements, neither follows.
Hence, the answer is that neither conclusion (I) nor (II) follows.
