1. Neuroscientists are making progress in discovering more about the cause of Alzheimer’s disease. Alzheimer’s disease patients suffer from dementia and sever memory loss. Autopsies performed on such patients have revealed the presence of brain lesions caused by abnormal protein deposits. Similar deposits are also found in the brains of elderly patients who do not suffer from Alzheimer’s disease. It follows that everyone who lives long enough will eventually develop Alzheimer’s disease.

2. Top college graduates are having more difficulty demonstrating their superiority to prospective employers than did the top students of twenty years ago when an honors degree was distinction enough. Today’s employers are less impressed with the honors degree. Twenty years ago no more than 10 percent of a given class graduated with honors. Today, however, because of grade inflation, the honors degree goes to more than 50 percent of a graduating class, Therefore, to restore confidence in the degrees they award, colleges must take steps to control grade inflation.


--LSAT Section One No.13




3.Older United States automobiles have been identified as contributing disproportionately to global air pollution. The requirement in many jurisdictions that automobiles pass emission-control inspections has had the effect of taking many such automobiles out of service in the United States, as they fail inspection and their owners opt to buy newer automobiles. Thus the burden of pollution such older United States automobiles contribute to the global atmosphere will be gradually reduced over the next decade.

4.The brains of identical twins are genetically identical. When only one of a pair of identical twins is a schizophrenic, certain areas of the affected twin’s brain are smaller than corresponding areas in the brain of the unaffected twin. No such differences are found when neither twin is schizophrenic. Therefore, this discovery provides definitive evidence that schizophrenia is caused by damage to the physical structure of the brain.

5. Every photograph, because it involves the light rays that something emits hitting film, must in some obvious sense be true. But because it could always have been made to show things differently than it does, it cannot express the whole truth and, in that sense, is false. Therefore, nothing can ever be definitively proved with a photograph.

        1. Scientist explored the reason for people getting Alzheimer disease found that this disease is caused by the accumulation of some kind of deposits. Since this kind of deposits are also found in old people, everyone would get Alzheimer disease only if they live long enough.

Getting old = accumulation of deposits = Alzheimer disease

        2. Employers nowadays are paying less attention on the distinction of the graduate's degree than 20 years ago. It is because of degree inflation, which led to a higher percentage of student who got the distinction. So in order to rebuild the confidence of employers on distinction, colleges should give away less distinction.

Degree inflation --> more distinction --> less confidence of employers

        3. Since the older factories of the US are releasing more pollutions to the atmosphere, the US government is giving less permission on this kind of factory and thus the pollution will be less in the future.

Less permission --> less older factories --> less pollution

        4. The brains of a pair of twins are identical. However, if a kind of disease is affecting one of the twins, some areas of the affected twins will be smaller than the areas of the unaffected twins. When there is no such an affection, there is no differences between the brains of the twins. Thus, the disease is influencing the physical structure of the brain.

With disease --> smaller areas in the brain --> the disease affect the physical structure

        5. Since there are always something that can not be shown by a photograph, the photograph should not be relied on in proving things.

1-39s
premise: A这种疾病是某种abnormal brain protein deposit导致的；而这种protein也会在没有得A这种病的老年人中发现
Conclusion：所有人如果live long enough都会得A这种病
Paraphrase： 所有人如果live long enough都会有这种protein 所以都会得A这种病

2-30s
讲的是学历通胀
premise：现在的学生没20年前的学生能够向公司证明自己qualify了
premise: 原来只有10%能拿奖学金，现在拿的人很多，所以只有honor也不够用
conclusion: school should control grade inflation
paraphrase: 学校如果想要重拾学生们在雇主面前的自信，就应该去控制成绩膨胀，让学习好的学生真正凸显出来

3.40S
premise: 美国的一部分空气污染是由摩托车导致的
premise: 在车辆审查当中很多的摩托车都没有通过所以车主就被迫去买新车了
conclusion: 因此呢由摩托车导致的污染会逐渐消失的
paraphrase: 从不符合规定的旧车换到新车就会让空气污染逐渐消失。

4-45S
premise: twins have identical genetic brain structure.
premise: 有一种病S，会让twins中的一个的一部分会比另一个正常的人的那一部分在脑中的占比更小
conclusion：因此S这种病是因为某种physical damage 导致的

5-35s
premise：照片里面有一些光线会导致想表达的内容不真实
conclusion: 照片不能作为证据
paraphrase: 因为照片有某种技巧，他就不可信了？

p：得a病的人被发现脑部得损伤是由一种deposit导致的，而在没得a病得人脑子里也有这个deposit
c：所有人最后都会得a病的
类比推理：削弱方向是两种人的不同，比如没得a病里的这个deposit的数量根本不会引起脑部损伤，只有足够多的deposit才会引起脑部损伤

2.30s
p：以前grade honor很值钱，现在因为数量太多了，所以都不值钱了。
c：所以为了提高这些有honor的人的自信，应该严格控制honor的数量
方案推理：削弱，严格控制honor的话会让以前得honor的人觉得自己不够好不应该得这个honor，会让他们更不自信

3.45s
p：老车会造成很多污染，所以有inspection出台，这些用老车的人就必须抛弃老车去买新车了
c：环境污染会减少很多
因果推理：削弱，新车会和老车造成一样多的污染

4.45s
p：双胞胎很多生理结构都很像。得s病的双胞胎被发现脑子里有个部分比没得s病得双胞胎要小
c：得s病是由于大脑损伤造成得
相关因果：削弱，可能是大脑损伤才造成这个部分更小；

the cause of A disease 45s  
Con: everyone old enough will eventually have A disease
premise:
- if A disease, then high protein in brain.
- Old people, no A disease, also high protein.
dementia 痴呆    lesions损伤

the grade inflation 45s
Con: to restore the graduates confidence in degrees, college must control the grade inflation
Premise:
- 20 yrs ago, 10% get honor degrees; today, because of grade inflation, 50% get honor degrees = the honor degree of 20 years ago is much more precious than now
- graduates loss confidence, employers less impressed with the honors degree

old American automobiles 45s   
con: the older American automobiles will contribute to the global air pollution less in the next few decades
Premise:
there are rules making older American automobiles quit the service
car owners opt to buy new vehicles
理解错误：The requirement (in many jurisdictions that automobiles pass emission-control inspections) has had the effect of taking many such automobiles out of service in the United States, as they fail inspection and their owners opt to buy newer automobiles (因果).
很多机动车排放控制检查的要求已经让很多这种机动车不再上路了，因为这些车没有通过检查，所以车主就选择买新车了。
opt to do 选择做某事   

identical twins 45s
background: twins have identical brains  the brain of identical twins are genetically identical
premise:
if only one of a pair of twin is a S, certain part of his brain is smaller than than of another pair of twin
if none of the twin is S, no differences have been found
con: S is caused by damage to the physical structure of brain

photographs 45s
premise:
because of some principle, photographs always show things different from they are
photographs cannot express the whole truth
con: nothing can be definitely proved by/with a photograph

C: pollution caused by old automobile in US will reduce
B: old car polluted air, old car out of service
P: old car cause pollution, lots of old car are no met requirement, stop in service

Read twice-
C: S is not caused by damage to the physical structure of the brain
B: study of S of twin’s brain and show the S is not caused by physical damage
P: brains in twins are the same, but the one wit S is different, both have S the brains are the same

C: photograph can not be fully trust
P: photograph shows what it is show, but intentionally not showing what they don’t want to be shown
B: the reality of photograph

P 相同双胞胎大脑也基因相同，其中一个若为精神分裂 则其受影响那部分区域会比另个没受影响得小 然而在两个很正常双胞胎中没有发现这类不同
C 精神分裂是由于大脑物理结构受损造成

5. Every photograph, because it involves the light rays that something emits hitting film, must in some obvious sense be true. But because it could always have been made to show things differently than it does, it cannot express the whole truth and, in that sense, is false. Therefore, nothing can ever be definitively proved with a photograph.
