1.
Court records from medieval France show that in the years 1300 to 1400 the number of people arrested in the French realm for "violent interpersonal crimes" (not committed in wars) increased by 30 percent over the number of people arrested for such crimes in the years 1200 to 1300. If the increase was not the result of false arrests. therefore, medieval France had a higher level of documented interpersonal violence in the years 1300 to 1400 than in the years 1200 to 1300.
Which one of the following statements, if true, most seriously weakens the argument?


--LSAT3 SECTION1 NO.9


Key:
In the years 1300 to 1400 the French government's category of violent crimes
included an increasing variety of interpersonal crimes that are actually nonviolent.


2.
Rhizobium bacteria living in the roots of bean plants or other legumes produce fixed nitrogen which is one of the essential plant nutrients and which for non-legume crops, such as wheat normally must be supplied by applications of nitrogen-based fertilizer. So if biotechnology succeeds in producing wheat strains whose roots will play host to Rhizobium bacteria. The need for artificial fertilizers will be reduced.
The argument above makes which one of the following assumptions?


--LSAT3 SECTION1 NO.10


Key:
Rhizobium bacteria living in the roots of wheat would produce fixed nitrogen.


3.
If we are to expand the exploration of our solar system. Our next manned flight should be to Phobos one of Mars’s moons, rather than to Mars itself. The flight times to each are the same, But the Phobos expedition would require less than half the fuel load of a Mars expedition and would, therefore, be much less costly. So, it is clear that Phobos should be our next step in Space exploration.
Which one of the following, if true, would most help to explain the difference in fuel requirement?


--LSAT3 SECTION4 NO.2


Key:
Lift-off for the return trip from Phobos requires much less fuel than that from Mars because of Phobos weaker gravitational pull.


4.
Lourdes: Dietary fiber is an important part of a healthful diet. Experts recommend that adults consume 20 to 35 grams of fiber a day.
Kyra: But a daily intake of fiber that is significantly above that recommended level interferes with mineral absorption, especially the absorption of calcium. The public should be told to cut act on fiber intake
Which one of the following, if true, most undermines Kyra’s recommendation?


--LSAT3 SECTION4 NO.6


Key:
Among adults, the average consumption of dietary fiber is at present approximately 10 grams a day.


5.
The following appeared in an ad for a book titled How to Write a Screenplay for a Movie:
“Writers who want to succeed should try to write film screenplays rather than books, since the average film tends to make
greater profits than does even a best-selling book. It is true that some books are also made into films. However, our nation’s film
producers are more likely to produce movies based on original screenplays than to produce films based on books, because
in recent years the films that have sold the most tickets have usually been based on original screenplays.”
Discuss how well reasoned . . . etc.

1. 40s
Conclusion: 1300-1400 more people commit violent crimes
Premise: The number in 1300-1400 rose by 30% compared to the number in 1920-1930

Weaken: Lots of people are not arrested in 1920-1930

2. 38s
Conclusion: If the root of wheat can be altered to play host for R, artificial nitrogen will be reduced.
Premise: R bacteria can support nitrogen to some plant but cannot support nitrogen to wheat

Assumption: Wheat can absorb the nitrogen supported by R bacteria

3. 40s
Info1: The time to P is equal to the time to Mars
Info2: The fuel needed to get P is less than that needed to get Mars

Resolve: Sth. make P different from Mars

4. 32s
Kyra: We should cut act on fiber intake
Lourdes: Plentiful consumption of fiber is essential, 20-30 gram

Weaken: Currently, no one consume as much as 20-30 gram

1，
premise：the number increase 30%, the increase was not the result of false arrests
Conclusion: 1300~1400 had a higher level of documented interpersonal violence.
2。这个理解的跟superbat28 貌似有点不太一样。。。是我理解错了不~？求解~~
background information: R is living in the roots of bean plants and is one of the essential plant nutrients.
premise：normally, the wheat must be supplied by the nitrogen-based fertilizer
Conclusion: if the root will be the host of R, the fertilizers will be reduced.
3.
background: the flight time to P and M is the same
premise: to P, the fuel is much less than to M
Conclusion: our next step should be P.
4.
Lourdes: dietary fiber is important 20~35 a day
Kyra: the intake of fiber is above the level interfers with the mineral absorption, especially the calcium
Conclusion: the public should be told to cut act on fiber intake
介个逻辑链是个什么意思。。。。。。。
5.
Conclusion: writers who want to succeed should write film screenplays
Premise: 1. More profits in film screenplays than books.
         2.films are more based on the original screenplays

第二题没有什么不一样啊~哪里不同><

daisyの小夢想

1. 42s
Premise:
According to Court record,
The people who has commited violent interpersonalcrimes and has been arrested in 1300-1400 was far more than those in 1200-1300.
The increase was not a result of false arrest.
Conclusion:
There must be a higher level of violent interpersonal crimes documented in 1300-1400.
Weaken:
Arrested≠documented??

2. 39s
BG: R bacterium has N that provides nutricients for plants.
Premise:
If plants can produce N by nitrogen-based fertilizer with R, the need for artificial fertilizers can be reduced.
Assumption:
The nutricient received by nitrogen-based fertilizer  is no less than artificial fertilizers.
The nutricient received by nitrogen-based fertilizer can be applied to the plants.

3. 30s
Premise:
If we are to explore solar system, our next stop is Mars's Moon P.
Though P is as far away from the earth as is Mars, it cost only half of the fuel to go to P and thus cost less.
Conclusion:
We should go to P instead of the Mars.
Explain:
The fuel needed for the exploration to P is different from that for exploration to Mars, costing much more.

4. 37s
L: Fiber is essential for healthy diets. Doctors recommends that
people comsume X amount of fiber a day.
R：
However, consuming excessive fiber can have a detrimental impact.
Thus, people should decrease the amount of fiber that they comsume every day.
Weaken B:
The amount of fiber that people now consume every day is far less than that is required every day.

5. 45s
Conclusion:
For more success, writers should write screenplays rather than books.
Premise:
The avearage profit of films is much more than the profit of best-selling books.
The film producers tend to prefer screenplays rather than books for films.
1. average--> 个别
2. sales statistics in recent years are not sufficient indicator of screenplays' success.
3. either or choise. The writer can take both strategies.
