Among consumers in this country who take cruises regularly, the percentage who chose High Seas’ cruise lines has decreased by 5 percentage points over the past five years. Since High Seas obviously relies on consumers to earn profits, these declines must have had a measurably negative impact on High Seas’ earnings.

Which of the following, if true, most seriously weakens the argument above?

(A) Some trips were cut from the cruise schedule, and they were trips during which ticket sales had historically been sufficient to achieve profitability.
(B) There are many more cruise lines in existence today than there were five years ago.
(C) The number of people who regularly take cruises has increased significantly over the past five years.
(D) Five years ago, High Seas reduced the number of cruises on its annual schedule.
(E) High Seas cruises travel to several different destinations.

hi.
Para tells us that the people choosing H has gone down by 5% of total people who went on cruise..
so the profit must have gone down ... BUT this is not true, what can be the reasons..


1) the prices of tickets could have gone up resulting in more revenue..
example 100 went initially and profit was $100 so total $10000..
Now it is 95 but profit on each ticket has gone up to 200, so total = 200*95=$19000

2) since we are talking about %, it is possible even with lesser %, the actual numbers could have gone up.
earlier they had 50% of total , which is 100 people..
but now the % has gone down to 45 but the number of people on cruise has gone up to 200, so total on H cruise = 45*200/100=90
so increase from 50 to 90

point 2 is given by C
Quote:
(C) The number of people who regularly take cruises has increased significantly over the past five years.

I personally chose A, because it's a weakener. However, I have to admit that C is a stronger weakener as it refers to a "significant" increase in customers compared to "some trip, which got cut" in A.

Additionally, chetan2u explained it very well imo.

(C) The number of people who regularly take cruises has increased significantly over the past five years..

But in C how can we say that out of the number of people who take cruise, some portion belongs to High Seas cruises?
I guess A is a better weakner.

So to think of it in pure mathematical terms, say there were initially 100 people that booked cruise trips. Out of which 10% (making up a number) was High Seas cruise line's share (so 10 customers in total). The premise says that HS company's share of the customer pie has reduced to 5% now. And the conclusion is that it must be suffering financially because (10% to 5% obviously is bad, lower share blah blah). BUT, if the total number of customers increased to say 500 or 1000, then 5% of that share doesn't sound that bad, does it? so the company may not be suffering financially if the number of customers increased.. (weakener)

Regarding (A) why does not this answer choice acts as an alternate cause for the
effect - reduction in profitability ?
We already know that trips which were cut from schedule were profitable from the answer choice.
