1.The ability to analyze genomes — sequences of DNA — has grown more and more sophisticated. Scientists are able to examine the biological past in finer detail and with greater accuracy. A new analysis of the genetic links between early humans and chimpanzees has led to a hypothesis that the two species diverged more recently than previous estimates indicated. This gives credence to a very startling new theory: the ancestors of humans and chimpanzees might have hybridized to produce the lineage from which modern humans eventually developed. What can be inferred from the statements above?

A Hybridized species combine the best of both lineages.

B Political and religious pressures will affect the course of future research.

C Future research will enable scientists to determine the exact characteristics of this hybrid ancestor of modern man.

D Earlier genome analysis established genetic links between early humans and chimpanzees.

E Human DNA is more complex than that of chimpanzees.

2. The restaurant business wastes more energy than any other industry in the United States. Nearly 80 percent of the $10 billion spent on energy by the restaurant industry each year is squandered by the use of inefficient equipment. At the same time, approximately 70 percent of restaurants in the United States are small businesses that are usually too cash poor to invest in energy-efficient technology. Which of the following statements draws the most reliable conclusion from the information above?

A The availability of energy-efficient equipment will reduce the energy costs of the restaurant industry by approximately 30 percent.

B No industry in the United States spends greater than $10 billion each year on energy.

C By using energy-efficient technology, a small restaurant will reduce its expenses by a greater percentage than will a large restaurant.

D Approximately $2 billion of the amount spent on energy each year by the restaurant industry is not squandered.

E The replacement of inefficient equipment represents the largest potential source of energy savings for the restaurant industry.

题型：must be true-bible——原文说了分析DNA的科技进步导致一种新假设和有假设带来的新理论。——这个题比较有意思的是：之前bible一直在强调要小心might be true 的答案，所以如果是must be true一定是stimulus当中可以推出任何条件下都成立的statement。以往都是用原文信息顺推，这个题的则是倒退，即用原文给的信息逆向推理——用原文的new analysis of the genetic links between early human and chimpanzees...，既然是基于某种理论的新分析，那该理论肯定已经存在，即D选项。
题型：Main conclusion——原文说了两件事情：餐饮业每年话100亿美元在能源上，其中80%的费用是因为使用低效设备导致；美国餐饮业70%是中小型企业无法负担更换节能设备。——还是对于百分数理解不到位，很容易对剩余部分采用简单的取非方法来判断，比如这里说80%的钱因为使用低效设备，我就以为剩下的20%没有被浪费，其实原文只能证明剩下的20%没有被浪费在低效的设备上，有可能浪费在其他事情上面也有可能——正确答案被快速排出，因为看到答案使用了largest，愚蠢的认为是用百分数推测总数，但是原文已经给出了餐饮业花在能源的上的总数，所以当然换设备是最省钱的

2. Nearly 80 percent of the $10 billion spent on energy by the restaurant industry each year is squandered by the use of inefficient equipment. 80% 的能源因为使用不高效的机器而被浪费。 剩下20% 可能是不是因为机器被浪费的

1. 【Inference】D
A. the best of -- Wrong tone.    B. OUT OF SCOPE.    C. Future R Irrelevant E. more complex NOT SURE

2. 【Conclusion】E
Energy $10 b -- 80% inefficient E -- 70% poor XE - ?
D有点干扰，看起来80%浪费了 20%就没有浪费，不全面； 搬运解析：
(D)根据题干，80亿美元(每年100亿美元的能源支出的80%)被浪费在低效设备 上。题干还有20亿美元没有计算在内。这并不一定意味着这20亿美元中的一些 没有被挥霍;这只是意味着它没有被挥霍在低效设备上。例如，它可能被挥霍 在关门后忘记关灯的员工身上。
(E)正确。由于使用低效设备造成的浪费占每年100亿美元能源支出的80%，从其 他方面节省的费用最多只能占100亿美元的20%。因此，到目前为止，更换低效 设备是最大的潜在能源节约来源。
