LSAT 3—— 2—— 21 21. During construction of the Quebec Bridge in 1907, the bridge’s designer, Theodore Cooper, received word that the suspended span being built out from the bridge’s cantilever was deflecting downward by fraction of an inch. Before he could telegraph to freeze the project, the whole cantilever arm broke off and plunged, along with seven dozens workers, into the St. Lawrence River. It was the worst bridge construction disaster in history. As a direct result of the inquiry that followed, the engineering “rules of thumb” by which thousands of bridges had been built went down with the Quebec Bridge Twentieth-century bridge engineers would thereafter depend on far more rigorous applications of mathematical analysis.
Which one of the following statements can be properly inferred from the passage?
(A) Bridges built before about 1907 were built without thorough mathematical analysis and therefore, were unsafe for the public to use
(B) Cooper’s absence from the Quebec Bridge construction site resulted in the breaking off of the cantilever.
(C) Nineteenth-century bridge engineers relied o their rules of thumb because analytical methods were inadequate to solve their design problems.
(D) Only a more rigorous application of mathematical analysis to the design of the Quebec Bridge could have prevented its collapse
(E) Prior to 1907 the mathematical analysis incorporated in engineering rules of thumb was insufficient to completely assure the safety of bridges under construction. 我觉得选D要更好一些呢，虽然答案是E 文章推理不出07年前就是不能用数学方法来计算设计的安全性啊，也可能很早就能用只是一直没有采用呢
2—— 2—— 12 12. “Though they soon will, patients should not have a legal right to see their medical records. As a doctor, I see two reasons for this. First, giving them access will be time-wasting because it will significantly reduce the amount of time that medical staff can spend on more important duties, by forcing them to retrieve and return files. Second, if my experience is anything to go by, no patients are going to ask for access to their records anyway.”
Which one of the following, if true, establishes that the doctor’s second reason does not cancel out the first?
(A) The new law will require that doctors, when seeing a patient in their office, must be ready to produce the patient’s records immediately, not just ready to retrieve them.
(B) The task of retrieving and returning files would fall to the lowest-paid member of a doctor’s office staff.
(C) Any patients who asked to see their medical records would also insist on having details they did not understand explained to them.
(D) The new law does not rule out that doctors may charge patients for extra expenses incurred specifically in order to comply with the new law.
(E) Some doctors have all allowing their patients access to their medical records, but those doctors’ patients took no advantage of this policy.
这题的答案是A,可问题中的if true, establishes that the doctor’s second reason does not cancel out the first? 是什么意思呢 cancel out是补偿抵消的意思吗？
