Concept:In syllogism, assume all statements true and accept a conclusion only if it is definitely true in every possible Venn diagram.
Formula:Rule: “Only
A are
B” means all
B are
A.
Solution:From statement I, all drawings are drafts.
So drawings lie inside drafts.
Statement II says some drafts are maps.
So some maps are drafts.
Conclusion I says some highways are drawings.
No definite link is given between highways and drawings.
So conclusion I does not follow.
Conclusion II says no map is draft.
But statement II says some drafts are maps.
This makes “no map is draft” false.
So conclusion II also does not follow.
Hence neither conclusion follows.
Answer:Option C. Neither conclusion I nor II follow.
