jeff the undergraduate who make the summary for math. really appreciate you. although my math sucks this time. less than 6 JJ.

1) the AB=AC. HOW MANY BC VALUE THERE C IS integer. chose 6. A(00) B(3 1 ).

2) 8 VALUE BUT b takes one up. and there are two value the same. follow JEFF'S JJ. SAVE TIME ALOT

3) PIGGY BANK, CONTENT 5,10,25 CENTS,3.2 USD TOTAL. 29 COIN. 3 TIMES AS MANY 10 CENTS AS 25.

ANW:3,6,9,15,21.  i can find the right one. but i choose 15.

1)      Lizard: article the same.

 New questions: a) why do sympatric(asking those in the same habits) specie resemble each other. Anw: they live in the same habits

b) from DNA test what can we infer.

Anw: independent evolutionà species in one island genetically related more closely than sympatric species in different islands.

2)      GWD12-35. Investment and inflation rate

3)      New Dolphin: P1 use acoustical method in a environment with noisy. P2 talk about why they can avoid the noise. Basically only focus how the acoustics works. Detect clicks by repeat rate, change of frequency is not in a fixed pattern. Whistle frequency change in a consistent pattern

Q1: TOPIC. D,E is close in the words used. But E is correct. D—present a the information about a problematic issue in environment of particular animal. E—explain a the method used for a problematic issue in environment of particular.

Q2. what is the right about the whistle and clicks.

4)      HAWAI temple.

口述历史讲述17世纪初有个大牛人P统一了夏威夷 two tribes during into a peace and religious (part of the except Q2 here) society，Researchers think the social politics change of Hawaii happened in a single period of history.但无法证明，因为相关证据无法用C dating 测定年代。

Recently, researchers are able to date the using Tech U230 and U238. Sth from coral near the beach is used in the wall of temple. Scientist date with materials extract from both
    the coral in the sea and the coral material in the wall.(part of the except Q2 here)

Because the coral can absorb U230 and U238(I think from the sea. None of them in the air)

It proves that many temples shows up in a short period of time. Temples were used as a center to control the production and collect surplus foods. Therefore, prove the is a sudden society change in this period and it confers what oral history said and。最(证明夏威夷社会政治的发展比预想快 topic pretty sure ).

Q1:TOPIC证明夏威夷社会政治的发展比预想快 topic

Q2: CAN INFER EXCEPT a) is Hawaii society formed by the king religious?

b) why scientist can not prove Hawaii happened in a single period of history originally?
    

 Awn: the material is used in the wall is for structure soundness?

SC: not too taught for me. Lucky.

1)     Not by …………but also by.  ( there is one very close don’t use also only use but. Although the tense seems better)

2)     …….scientists use a alloy titanium, not so much reflect lights but it captures the light and send it back , tinted in gray or some other colors

No any anw I expect like, not reflect light so much, but capture ….

All with not so much reflect.

Attention on the reflects or reflect.

2、In 1960’s studies of rats, scientists found that crowding increases the number of attacks among the animals significantly. But in recent experiments in which rhesus monkeys were placed in crowded conditions, although there was an increase in instances of “coping” behavior-such as submissive gestures and avoidance of dominant individuals-attacks did not become any more frequent. Therefore it is not likely that, for any species of monkey, crowding increases aggression as significantly as was seen in rats.

Which or the following, if true, most strengthens the argument?

A.      All the observed forms of coping behavior can be found among rhesus monkeys living in uncrowded conditions.

B.      In the studies of rats, nondominant individuals were found to increasingly avoid dominant individuals when the animals were in crowded conditions.

C.     Rhesus monkeys respond with aggression to a wider range of stimuli than any other monkeys do.

D.     Some individual monkeys in the experiment were involved in significantly more attacks than the other monkeys were.

E.      Some of the coping behavior displayed by rhesus monkeys is similar to behavior rhesus monkeys use to bring to an end an attack that has begun.

13、N国不允许用抗生素，X国允许，抗药性强的细菌通过商品出口从X传道Y，Y国加强关税减少进口，

问加强 the effective of the plan by X

：1) Y国为了避免高关税会CHANGE the law to avoid the punitive tariff

2) Y should take measure to restrict the access to the antibody in the country. (I chose this one)

Key: WHAT IS THE PURPOSE OF X plan: reduce the anti-drug microbe from Y. howà reduce microbe in Y HOWà reduce the cause: access to anti-body

1)      can only weaken it unless Y change the law to reduce the access of the antibody

GWD23-Q40:
Political advocacy groups have begun to use information services to disseminate information that is then accessed by the
public via personal computer.  Since many groups are thus able to bypass traditional news sources, whose reporting is
selective, and to present their political views directly to the public, information services present a more balanced
picture of the complexities of political issues than any traditional news source presents.

Which of the following is an assumption on which the argument above depends?

A. Information services are accessible to enough people to ensure that political advocacy groups can use these
         services to reach as large a percentage of the public as they could through traditional news sources.
B. eople could get a thorough understanding of a particular political issue by sorting through information provided
        by several traditional news sources, each with differing editorial biases.
C. Information on political issues disseminated through information services does not come almost entirely from
         advocacy groups that share a single bias.
D. Traditional news sources seldom report the views of political advocacy groups accurately.
E. Most people who get information on political issues from newspapers and other traditional news sources can readily
        identify the editorial biases of those sources.
   Answer: C
