2) GWD12-35. Investment and inflation rate
Q35 to Q37:
Many economists believe that a
high rate of business savings in the
United States is a necessary precursor
Line to investment, because business sav-
(5) ings, as opposed to personal savings,
comprise almost three-quarters of the
national savings rate, and the national
savings rate heavily influences the
overall rate of business investment.
(10) These economists further postulate
that real interest rates—the difference
between the rates charged by lenders
and the inflation rates—will be low when
national savings exceed business
(15) investment (creating a savings surplus),
and high when national savings fall
below the level of business investment
(creating a savings deficit ). However,
during the 1960’s real interest rates
(20) were often higher when the national
savings surplus was large. Counter-
intuitive behavior also occurred when
real interest rates skyrocketed from
2 percent in 1980 to 7 percent in 1982,
(25) even though national savings and
investments were roughly equal
throughout the period. Clearly, real
interest rates respond to influences
other than the savings/investment
(30) nexus. Indeed, real interest rates may
themselves influence swings in the
savings and investment rates. As real
interest rates shot up after 1979, for-
eign investors poured capital into the
(35)
United States, the price of domestic
goods increased prohibitively abroad,
and the price of foreign-made goods
became lower in the United States. As
a result, domestic economic activity
(40) and the ability of businesses to save
and invest were restrained.

Q37:
The author of the passage would be most likely to agree with which of the following statements regarding the economists mentioned in line 1?
- Their beliefs are contradicted by certain economic phenomena that occurred in the United States during the 1960’s and the 1980’s.
- Their theory fails to predict under what circumstances the prices of foreign and domestic goods are likely to increase.
- They incorrectly identify the factors other than savings and investment rates that affect real interest rates.
- Their belief is valid only for the United States economy and not necessarily for other national economies.
- They overestimate the impact of the real interest rate on the national savings and investment rates.

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 ).

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?

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.

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
