1.CR

Dolphins have long been considered highly intelligent animals due to their large brain size relative to their body size. However, recent research has shown that a significant portion of a dolphin's brain is composed of fatty tissue, which evolved to serve a specific function unrelated to intelligence. Therefore, the large brain size of dolphins does not necessarily indicate higher intelligence compared to humans.
Which of the following best describes the flaw in the reasoning of the recent research regarding dolphin intelligence?
(A) It assumes that a characteristic that evolved for one function cannot serve any other functions.
(B) It fails to consider that intelligence is not solely determined by the ratio of brain size to body size.
(C) It does not provide evidence that the fatty tissue in dolphin brains is unrelated to intelligence.
(D) It relies on the false premise that humans are the most intelligent species.
(E) It overlooks the possibility that the specific function of the fatty tissue may contribute to intelligence.

A study found that people who read more than one recreational book per year are more likely to attend museums, concerts, and art exhibitions than those who read less than one book per year. The author concludes that reading recreational books encourages people to develop interests in such activities.
Which of the following best describes the flaw in the author's reasoning?
(A) The author assumes that reading books is the only factor influencing people's interest in attending cultural events.
(B) The author fails to consider that people who enjoy cultural activities may be more likely to read recreational books.
(C) The author does not provide evidence that reading non-recreational books has the same effect on people's interests.
(D) The author overlooks the possibility that a third factor, such as education level, may influence both reading habits and interest in cultural activities.
(E) The author relies on a small sample size that may not be representative of the general population.

2.RC

The penetration of formal insurance among low-income populations in developing countries remains low. Under such circumstances, some researchers theorize, social capital can lead to better informal risk-sharing among households. By increasing the social ties between individuals, development organizations may be able to expand or deepen their informal risk-sharing networks and help the poor hedge against individual or household level-risks.  Some experts believe that greater social capital can lead to other advantageous economic outcomes for the poor such as increased cooperation. For these reasons, many development organizations attempt to build social capital through programs that focus on community interaction and group activity.

In this study, CMF researchers tested whether one development intervention that involves constant group interaction, standard microfinance lending, builds social capital. By closely tracking borrowing outcomes for groups that meet more frequently, researchers attempted to quantify the returns to enhanced social capital.

Researchers used several randomised experiments to test whether or not increased microfinance meeting frequency leads to increases in social capital. The study was conducted in the impoverished urban and peri-urban parts of West Bengal, India, with the help of Village Welfare Society (VWS), an MFI operating in the state. Researchers randomized traditional microfinance borrowing groups into either a monthly repayment cohort or a weekly repayment cohort.
There were broadly two kinds of experiments:

Testing for effects of more frequent interaction – Researchers chose 100 first-time loan client groups, each consisting of 10 members. The members of a group generally lived in close to each other or were neighbours. Surveyors randomly selected 30 of these groups to weekly meetings and the rest (70 groups) to attend monthly meetings. The MFI provided approximately Rs. 4000 in loans to each member. The first group had to make weekly repayments of Rs. 100 starting two weeks after loan disbursal and the second group was required to make monthly repayments of Rs. 400 after the first month.

Testing for trust among group members – Researchers ran another experiment more than a year later in which select loan clients from the same groups were given lottery tickets to thank them for participating in the first loan experiment. The client could choose any number of her group members to receive lottery tickets. If the client trusts that the other members would share their winnings with her either directly or through reciprocal behaviour at a later point in time, this increases her expected gain and hence should motivate her to give out more tickets. The tickets are either of Rs. 200 or divisible into Rs. 50, these were randomly assigned to filter the effect of trusting others in the group from altruistic motives.

The study finds that weekly group members were 26% more likely to meet fellow members outside the group meetings compared to women who met monthly. The effects were stronger for women who lived closer to each other. Also, researchers found that while only about 10% of monthly group members had met everyone in their group other socially in the last 30 days, 100% of members in the weekly group had met socially.

The increase in social interaction among members who met more frequently was accompanied by increases in risk-sharing. The researchers found that weekly group members were 29% more likely to make transfers to their friends and distant family after the loan cycle. Though researchers could not directly trace borrower to borrower transfers, they observed increased risk sharing through the trust game. Weekly clients were 48% more likely to distribute Rs. 50 vouchers, an outcome which suggests that weekly clients, more so than monthly client,  saw their fellow group members as individuals who would make reciprocal exchanges.

Most significantly, default risk decreased for the groups that met more frequently – weekly group members were 3.5 times less likely to default on their loans compared to the monthly group members. Researchers conclude that in this case, default decreased, not because of the pressure to repay, but rather because individuals with enhanced social capital (weekly members) were more likely to share risk and make monetary transfers.

Higher meeting frequencies result in reduced default risks, which should theoretically reduce costs for the lending organization. However, the cost of conducting more frequent meetings is also high for the MFI and for the individual. Because both monthly meetings and weekly meetings have significant costs and benefits associated with them, it is hard to conclude that one approach is clearly better than the other. Given the short-term and long-term increases in social capital associated with weekly meetings, organizations holding monthly meetings should consider moving to a weekly schedule. To further inform the policy debate, academics should conduct on the costs borrowers incur in attending repayment meetings.

Many have discussed the merits of individual liability versus joint liability methodologies in microfinance. This study builds on literature that suggests that the joint liability feature of JLG is not the mechanism which guarantees repayment: rather this study finds that more frequent group meetings leads to increases in social capital which improve risk sharing, decreasing default.

Researchers should investigate whether other development programs are also successful at boosting social capital and whether increases in social capital led to economically significant outcomes.

1. The passage implies that the primary motivation behind development organizations' efforts to build social capital is to:
   (A) Increase the penetration of formal insurance among low-income populations
   (B) Encourage cooperation and risk-sharing among households in the absence of formal insurance
   (C) Reduce the costs associated with conducting frequent meetings in microfinance programs
   (D) Promote individual liability methodologies over joint liability in microfinance lending

   (B) The size of the loans provided to each member
   (C) The proximity of members' residences to one another
   (D) The level of trust among group members

   (B) Weekly clients were more likely to exhibit altruistic behavior towards their fellow group members
   (C) The value of the vouchers had a significant impact on the likelihood of distribution among group members
   (D) The distribution of vouchers was a direct measure of the level of risk-sharing among group members
   (E) The frequency of meetings had no influence on the level of trust among group members
4. The passage suggests that the debate surrounding the relative merits of individual liability and joint liability methodologies in microfinance:
   (A) Has been resolved by the findings of this study, which clearly favor joint liability
   (B) Is the primary focus of the research conducted by CMF researchers
   (C) Has not been directly addressed by the findings of this study
   (D) Is less relevant than the debate surrounding the optimal meeting frequency in microfinance
   (E) Can be informed by the study's findings on the relationship between meeting frequency and social capital

The Tarantella is a traditional Italian folk dance and music style that originated in the southern regions of Italy, particularly in Naples and Calabria. The dance is characterized by its fast, upbeat tempo and lively, energetic movements. The music that accompanies the Tarantella is typically played on instruments such as the mandolin, guitar, accordion, and violin, and features a rapid 6/8 or 3/8 time signature.

The origins of the Tarantella can be traced back to the Middle Ages, when it was believed that the frenzied dance could cure the bite of the tarantula spider. According to folklore, the spider's venom would cause a condition known as "tarantism," which could only be cured by dancing to the fast-paced music of the Tarantella until exhaustion set in.

The Tarantella is usually performed by couples, with the dancers dressed in traditional, brightly colored costumes. Men typically wear tight-fitting pants and vests, while women don long skirts and aprons. The dance steps involve quick, light footwork, leaps, and spins, with dancers often clapping their hands and shouting to the rhythm of the music.

Over time, the Tarantella has evolved to incorporate elements from other musical styles, such as jazz and rock, creating unique fusion genres. Many contemporary musicians and dancers continue to innovate and develop this tradition, bringing it to new heights of artistic expression.

Today, the Tarantella remains an essential part of southern Italian culture and is often performed at festivals and celebrations. Its lively melodies and energetic dance steps continue to captivate audiences around the world, serving as a vibrant expression of Italian folk heritage.

第一篇：social capital

Social capital带来的economic outcomes导致了many development organizations build social capital through programs

```
   CMF researchers设计实验来量化增强social capital的回报

对于下面两种实验的总概述，实验目的都是：增加meeting frequency是否会增加social capital
    第一个实验介绍-测试频率更高的接触影响：按照不同的频率要求贷款人还款给MFI
```

第二个实验操作过程介绍-测试组间成员的信任度：给loan clients彩票lottery tickets，clients可以选择他们组里收到彩票数量的成员数量。第二个实验原理介绍：如果clients预计组员会有互惠行为，那么他们就会增加收到彩票数量的成员。实验排除了altruism的影响（每个人都随机收到200元单张彩票或者50元4张彩票，然后看他们分出去多少）

```
   两个实验的结果阐述：Frequency增加，30天内更可能见面,组内成员trust度更高

Trust度升高的同时伴随着increases in risk-sharing（本段同时说明了frequency高的一组：trust高，risk-sharing也高）

研究结果：Meet more frequently还款失约的风险减少，是因为加强的social capital让他们share risk

研究结果中推荐的方法的缺点：这个实验结果显示moving to a weekly schedule更好，但还需要academics展开对borrowers参加费用的cost的研究

解释研究中容易弄混的概念：social capital是通过improve risk sharing, decreasing default 而不是joint liability
