Now is an excellent time to invest in the catering business. A survey conducted by Weddings magazine found that 70 percent of the magazine’s readers want a catered wedding reception. An analysis of the catering industry, however, shows that the current number of caterers can serve only 55 percent of the weddings likely to occur each year.
Which of the following, if true, would undermine the validity of the investment advice in the paragraph above?
(A) The average wedding reception involves between 50 and 100 guests.
(B) Approximately a quarter of all weddings take place without a reception.
(C) Approximately a quarter of all weddings and their associated receptions are paid for by the couples themselves.
(D) Only half of all catered wedding receptions include sit-down meals.
(E) Only half of those who say they want a catered wedding reception actually have one.
I wonder why choice B is not correct?
As for E, I have the question: is " the wedding likely to occur each year" is equal to the number of those who asay they want a catered wedding reception? That's to say, is there any conceptual discrepancies here, as usually used by ETS.
AND here it seems that 70% is not used at all.
Could NN give some reply, please?
Thank you very much! |
