The following data sufficiency problems consist of a question and two statements, labeled (1) and (2), in which certain data are given. You have to decide whether the data given in the statements are sufficient for answering the question. Using the data given in the statements plus your knowledge of mathematics and everyday facts (such as the number of days in July or the meaning of counterclockwise), you must indicate whether.
A farmer sells buckets of onions for $2, buckets of potatoes for $4, and buckets of squash for $5. How many buckets of squash did the farmer sell ？（）
(1) The farmer sold one bucket of onions.
(2) In total, the farmer sold 7 buckets of produce for $33.
A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
D. EACH statement ALONE is sufficient.
E. Statements (1) and (2) TOGETHER are NOT sufficient.
参考答案：B
解析：
alone is insufficient because it tells nothing about the number of buckets of potatoes or squash sold. (2) alone is sufficient, because there is only one combination of 7 buckets of vegetables with the listed prices that will result in a total price of $33:5 buckets of squash and 2 buckets of potatoes.
