Sets & Venn diagrams
Logic

Consider the statements $P$ : all students offering Literature ( $L$ ) also offer History ( $H$ ); $Q$ : students offering History do not offer Geography ( $G$ ). Which of the Venn diagrams correctly illustrates the two statements?

Worked solution (try it first)

Statement $P$ says every Literature student also offers History, so the circle $L$ sits inside the circle $H$ .
Statement $Q$ says History students do not offer Geography, so $H$ and $G$ do not overlap.
Diagram C shows $L$ inside $H$ with $G$ separate, option C.
