EN = negative impact on earnings

Literally, the author believes that the five percent decrease translated into fewer cruisers, which then lead to lower earnings. The question stem asks you to weaken the argument, and the correct answer falls into one of the five basic methods for weakening a causal argument.

Answer choice (A): The argument does not indicate or rely upon the assertion that trips were cut from the cruise schedule. Although cutting trips may be a cause of the five percent decrease (the cause of the cause), or, alternatively, an effect of lower earnings (the effect of the effect), it does not attack the causal relationship about whether the five percent decrease resulted in lower earnings.
