NO.1
Physician: In itself, exercise does not cause heart attacks; rather, a sudden increase in an exercise regimen can be a cause. When people of any physical condition suddenly increase their amount of exercise, they also increase their risk of heart attack. As a result, there will be an increased risk of heart attack among employees of this company due to the new health program.
The conclusion drawn by the physician follows logically if which one of the flowing is assumed?
(A) Employees will abruptly increase their amount of exercise as a result of the new health program.
NO.2
Last month OCF, Inc., announced what it described as a unique new product: an adjustable computer workstation. Three days later ErgoTech unveiled an almost identical product. The two companies claim that the similarities are coincidental and occurred because the designers independently reached the same solution to the same problem. The similarities are too fundamental to be mere coincidence, however. The two products not only look alike, but they also work alike. Both are oddly shaped with identically placed control panels with the same types of controls. Both allow the same types of adjustments and the same types of optional enhancements.
The main point of the argument is that
(C) The similarities between the two products are not coincidental.
NO.3
An anthropologist hypothesized that a certain medicinal power contained a significant amount of the deadly toxin T. When the test she performed for the presence of toxin T was negative, the anthropologist did not report the results. A chemist who nevertheless learned about the test results charged the anthropologist with fraud. The anthropologist, however, countered that those results were invalid because the power had inadvertently been test in acidic solution.
In the absence of the anthropologist’s reply, which one of the following principles, if established, would most support the chemist’s charge?
(E) Scientists who neglect to report any experiment that could be interpreted as disconfirming their hypothesis have thereby committed fraud.
Which one of the following, if true, most strengthens the anthropologist’s counterargument?
(C) When it is put into an acidic solution, toxin T becomes undetectable.
NO.4
Every year, new reports appear concerning the health risks posed by certain substances, such as coffee and sugar. One year an article claimed that coffee is dangerous to one’s health. The next year, another article argued that coffee has some benefits for one’s health. From these contradictory opinions, we see that experts are useless for guiding one’s decisions about one’s health.
Which one of the following most accurately describes a flaw in the argument above?
(E) The argument fails to consider that coffee may be harmful to one’s health in some respects and beneficial in others.

NO.5  AA
The following appeared as part of an article in a trade magazine:
“During a recent trial period in which government inspections at selected meat-processing plants were more frequent,
the amount of bacteria in samples of processed chicken decreased by 50 percent on average from the previous year’s
level. If the government were to institute more frequent inspections, the incidence of stomach and intestinal infections
throughout the country could thus be cut in half. In the meantime, consumers of Excel Meats should be safe from
infection because Excel’s main processing plant has shown more improvement in eliminating bacterial contamination
than any other plant cited in the government report.”
Discuss how well reasoned . . . etc.

Conclusion: The employees will have a higher risk of heart disease once the new program is effect
Premise: Increased exercise?increased risk of heart attack

Assumption: Employs did not expose to such high level of exercise previously (我想多了0 0)

2. 45s
Conclusion: The similarities cannot be a coincide
Premise: Both have similar unique design, and allow same adjustment
Counter-Conclusion: The similarity is a coincide, just because both companies use the same strategy to get the same result

3. 45s
Conclusion: The result was invalid
Premise: A situation that makes the material lose validity

Principle: If sb. do not report failure, he must have committed to a fraud
Support: No chance would the same situation leads to a valid result (好吧，我又想多了0 0)

AA好多flaw，好多flaw~~~
1. Although it the percentage has significantly decreased, it does not mean it has the potential to continue the decline, we need more analysis
2. 50% decline in the amount of bacteria does not mean that we will have a 50% decline in intestial report, since lots of other factors may conribute to the number of reports: such as people's physical condition....
3. A large improvement does not mean that the company is safe, becasue it may have a status that far below the industrial average~

P: The sudden increase of exercise will increase heart attack problem.
C: The new health program will bring the heart attack problems for the company employees.
Assumption: The new health program will offer intense exercise schedule for employees.


50s
P: The work stations that these two companies invented are the same because the inventors try to solve the same problem.
P: However, this cannot be coincidence merely, since the work stations not only function similarly, but also design similarly.
Conclusion: The work stations are coincident if based on their own independent designs to reach to the same solution.


45s
P: The chemist criticized that the anthropologist didn't announce her test result.
C: The anthropologist argued that her result is invalid because other factors are also involved.
Strengthen: The factors involved in the test are not stable to test the result.

26s
P: The report shows that coffee is good for human healthy, sometimes it shows the opposite.
C: The report from the expert about coffee effect on human's health is not trust able.
Flaw: The different ingredients of coffee can either benefit human's health or harm their health.

There will be an increased risk of heart attack if they have new health problem.
Assumption:
Such new health problem will change one's physical condition.

2.60s
Two companies' new products are extremely similar. They claim that it's coincidence. However, too much fundamental similarities...
Main Point: The similarity is not coincidence.

3. 40s
An anthropologist asserts that a medical power can be toxic.
But her test result is not what she assumes.
Her reasoning is that  the medical power has inadvertently been test in acidic solution.
Support:
What are toxic can lose effect in acidic solution.

4. 45s
One article claimes that coffee is beneficial to one's health.
Another article claims that coffee is detrimental to one's health.
Conclusion: Both of the articles are useless for people to decide whether to drink coffee.
Flaw:
两个观点contradict了，就不能参考其正确的理由。
人们依然可以根据其好处和坏处来做判断呀~

公司A发明了一个好东西，几天之后，马上公司B推出一个几乎一摸一样的产品。两个公司都说这是巧合，因为这个产品刚好很有用的解决了一个电脑问题。但是，这个巧合其实并不是那么fundamental。这个相似性并不仅仅是巧合。虽然两个产品看起来不一样，它们两个不仅看起来一样。但它们工作的原理，用的零件等等都是一样的。
推论：肯定有除了巧合之外的原理导致了这两个产品如此相像。
(C) The similarities between the two products are not coincidental. 总结上文

Government inspections is good for decrease incidence of people's stomach and intestinal infections.
So there should be more inspections. Meantime, Meat from Excel company is better than other's because Excel's main processing plant show more improvement.
