In the following question below are given some statements followed by some conclusions based on those statements. Taking 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 L are M.
All G are M.
All G are M.
Conclusion:
(I) No G is L.
(II) No M is L.
(III) Some M are G.
Answer & explanation
Correct answer: option 4
A Venn diagram based on the statements is:
1. There is no definitive relationship between G and L, thus conclusion I does not follow.
2. There is a clear overlap between L and M. thus conclusion II is not true.
3. Some M are definitively G, thus conclusion III follows.
