The use of phrases like “as so-and-so said” or “as the saying goes” suggests that the quote that follows has just been illustrated. Such phrases are counterexample has just been given.
What this question is testing
Principle
The principle is simple: "as the saying goes" should follow a story that illustrates the saying. If the story is actually a counterexample — the opposite of what the saying claims — then using "as the saying goes" is inappropriate.
Goal
So we are looking for the answer where the story and the saying do not match. Either the story is the reverse of what the saying claims, or it just does not illustrate the saying at all.
Read each example, ask: "Does this story actually fit the proverb?" The one where the answer is no is correct.
