Passage Summary: A historian thinks a political party won because they promised to help the farmers and small-town folks who were suffering the most during a bad economy.

Conclusion: The Land Party's 1935 victory resulted from a combination of targeting specific groups and the severity of the economic issues those groups faced.

Reasoning: The party focused on rural and small-business interests, which represented the majority of the population and were the hardest hit by the era's economic crisis.

Analysis: Since this is a 'Strengthen EXCEPT' question, four of the answers will bolster the historian's causal claim that the party's strategy plus the economy led to the win. To strengthen this, we might see evidence that these specific groups actually turned out in high numbers for the Land Party, or that other potential causes—like a charismatic leader—weren't actually factors. The 'odd man out' will either be irrelevant to the victory or will suggest an alternative reason for the win. It’s like trying to prove a recipe is the reason a cake is good; you want to show the ingredients were right and that it wasn't just a lucky oven.
