1. Problem Description
The problem asks us to choose the Venn diagram that correctly illustrates the following two statements:
P: All students offering Literature (L) also offer History (H).
Q: Students offering History (H) do not offer Geography (G).
2. Solution Steps
Statement P: "All students offering Literature (L) also offer History (H)" implies that the set L is a subset of the set H. In other words, L must be entirely contained within H. Mathematically, .
Statement Q: "Students offering History (H) do not offer Geography (G)" implies that there is no overlap between the set H and the set G. In other words, the intersection of H and G is the empty set. Mathematically, .
Now we analyze each option:
A. In this diagram, L, H, and G all intersect. In particular, H and G intersect, which violates statement Q. Also, L is not entirely contained within H, violating statement P.
B. In this diagram, G and H are separate, so . Also, H contains L, so . Both statements P and Q are satisfied.
C. In this diagram, G and H are separate, so . However, L is inside H, but H does not entirely contain L. This is a contradiction since L contains H, implying all H offer L, where the question statement is that all L offer H. This is not the correct implication.
D. In this diagram, H and G intersect, violating statement Q.
3. Final Answer
B
