Logical Reasoning Puzzle: Wendy and Selma's Photographs

Explanation:

The question presented is a logic puzzle often found in the Mathematics subject, particularly dealing with logical reasoning or deductive reasoning, which is a topic typically covered in high school. We are given a specific condition regarding Wendy and Selma's appearances in photographs and asked to make a logical deduction based on that information.

Given the statement that 'Wendy appears in every photograph that Selma appears in,' we can infer that if Selma is in a photograph, then Wendy must also be in that same photograph. However, we cannot make any assumptions about who is the photographer, how often they are together, or if Wendy appears in photos without Selma from this statement alone. Therefore, the correct answer to the puzzle is option D: 'Wendy is never in a photograph without Selma'.

It is crucial to understand that the presence of one individual (Selma) guarantees the presence of the other (Wendy) in these photographs, but the reverse may not necessarily be true unless explicitly stated.
