An insurance company has a contract with a medical laboratory to pay a discounted price for a certain medical test performed on patients referred to the laboratory by the insurance company. If the laboratory's original bill for this medical test on a patient referred by the insurance company is $230, what is the percent discount specified by the contract between the laboratory and the insurance company?
(1) The insurance company is required to pay only 20 percent of the original bill for the test.
(2) The insurance company is required to pay $46 for the test.
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.
真的会有直接告诉答案这种事情。。。
If the laboratory's original bill for this medical test on a patient referred by the insurance company is $230，这句话on a patient是修饰前面的test的，也就是说这个test是一个病人的test，on a patient是限定作用，所以一个test对应一个病人
题目提到这个测试是针对“病人们”的，“ a certain medical test performed on patients”，“on a patient referred by the insurance company is $230”价格是针对“一个病人”的，条件（2）未涉及病人数量，独立充分吗？
