Question
Statements: No lessons are topics. All
topics are headings. Some headings are introductions. All introductions are conclusions. Conclusions: I. Some lessons are introductions. II. Some conclusions are headings. III. Some headings are not conclusions. IV. Some lessons are not conclusions. In each of the questions below are given four statements followed by four conclusions numbered I, II and III and IV. You have to take the given statements to be true even if they seem to be at variance with commonly known facts. Read all the conclusions and then decide which of given conclusions logically follows from the given statements disregarding commonly known facts .Solution
No lessons are topics (E) + All topics are headings (A) = Some lessons are not headings (O), so further we can derive anything from it, hence conclusion I doesn’t follows and IV also doesn’t follows. Some headings are introductions.(I) + All introductions are conclusions.= Some headings are conclusions (A) ⟹  conversion ⟹  Some conclusions are headings. Hence conclusion II will follow but conclusion III doesn’t follows. Alternate Method:
