In each of the questions below are given three statements followed by four conclusions numbered I, II, III and IV. You have to take the given statements to be true even if they seem to be variance from commonly known facts. Read all the conclusions and then decide which of the given conclusions logically follows from the given statements disregarding commonly known facts.
Statements: Some buses are jungles. Some jungles are lions.
Some lions are rivers
Conclusions: I. Some buses are rivers
II. Some lions are buses
III. Some jungles are rivers
IV. All lions are either jungles or rivers
We use elimination to find an exception to the generality of the conclusions. Thus we prove they are not implied. The diagram below satisfies all the statements but contradicts all the conclusions. Since we found an exception, the conclusions are not true in "every" case. Thus they are not implied.
