Six countries in a certain region sent a total of 75 representatives to an international congress, and no two countries sent the same number of representatives. Of the six countries, if Country A sent the second greatest number of representatives, did Country A send at least 10 representatives?
(1) One of the six countries sent 41 representatives to the congress.
(2) Country A sent fewer than 12 representatives to the congress.
Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
EACH statement ALONE is sufficient.
Statements (1) and (2) TOGETHER are NOT sufficient.
（1）：有一个国家sent 41, 只能是最大的国家sent 41。 A作为第二大的国家，可能大于10、也可能小于10（因为之后国家可以任意在1-9间取值来满足）
比如：A大于10时——41，12，10，7，3，2。 A小于10时——41，9，8，7，6，4。
（2）：不知最大的数是多少，A取值不定。
（1）+（2）：一样无法确定。
