An argument asserts a direct causal link between two events. To most effectively strengthen this causal claim, what kind of additional evidence would be most beneficial for the original author to provide?

A A detailed historical account of similar situations in other contexts.
B Evidence demonstrating that the supposed cause consistently precedes the effect and that no other plausible causes are at play.
C A personal testimonial from someone who believes the causal link exists.
D Data showing a strong correlation between the two events without further analysis.

✓ Correct Answer: Option B

Strengthening a causal claim requires ruling out alternative causes and establishing consistent precedence, which strengthens the argument more than mere correlation, anecdotes, or historical parallels alone.
