[Q]: Article: "Ten years ago I could never have imagined I'd be doing this,"says Greg Pal,33,a former software executive. "I mean ,this is essentially agriculture ,right? But the people I talk to, especially the ones coming out of business school , think this is the one hot area everyone wants to get into ." He means bugs. To be more accurate, the genetic change of bugs---very, very small ones---so that when they feed on agricultural waste such as woodchip or wheat straw ,they do something extraordinary . They excrete crude oil. Unbelievably ,this is not science fiction .Mr. Pal holds up a small cup of bug excretion that could ,in theory ,be poured into the tank of the big Lexus SUX next to us .Not that Mr. Pal was willing to risk it just yet .He gives it a month before the first vehicle is filled up with what he calls "renewable petroleum ".After that ,he smiles ,"It's a brave new world." Mr. Pal is a senior director of LS9,one of several companies in or near Silicon Valley.The company is not interested in using corn as material ,given the much-advertised problems created by using food crops for fuel .Instead ,different types of agricultural waste will be used according to whatever makes sense for the local climate and economy :wheat straw in California ,for example ,or woodchip in the south. Are Americans ready to be putting genetically changed bug excretion in their cars? "It's not the same as with food,"Mr. Pal say ."We are putting these bacteria in a very isolated container. Their entire universe is in that tank .When we've done with them .they are destroyed." " Besides ",he says ,"there is greater good being served."" I have two children, and climate change is something that they are going to face .The energy crisis is something that they are going to face .We have a collective responsibility to do this."

[Q]: Article: More than a century ago, the composer and bandleader John Philip Sousa warned that technology would destroy music, who said, "These talking machines are going to ruin the artistic development of music in this country. When I was a boy ... in front of every house in the summer evenings you would find young people together singing the songs of the day or the old songs. Today you hear these terrible machines going night and day. We will not have a vocal cord left." Music has greatly changed in the past hundred years, which has been everywhere in our world: rivers of digital melody flow on the Internet or on disc; MP3 players with forty thousand songs can be put in a back pocket or a purse. Yet, for most of us, music is no longer something we do ourselves, or even watch other people do in front of us. It has become a radically virtual medium, an art without a face. Ever since Edison invented the phonograph cylinder , people have been assessing what the medium of recording has done for and to the art of music. Sousa was a spokesman for the party of doom; in the opposite corner are the utopians , who argue that technology has not imprisoned music but liberated it. Before Edison came along, Beethoven's symphonies could be heard only in select concert halls. Now the recordings carry the man from Bonn to the corners of the earth. Glenn Gould, after renouncing live performance in 1964, predicted that within the century the public concert would disappear into the electronic air. Having discovered much of my favorite music through LPs and CDs, I am not about to join Sousa's party. Modern urban environments are often so soulless or ugly that I'm grateful for the humanizing touch of electronic sound. But neither can I accept Gould's slashing futurism. I want to be aware of technology's effects, positive and negative. Fortunately, scholars and critics have been methodically exploring this _ for many decades, trying to figure out exactly what happens when we listen to music with no musicians in the room.
Question: The author's attitude towards the recorded music may best be described as _ .
Options: (A) dissatisfied (B) defensive (C) optimistic (D) objective

[Q]: Article: The Italian island of Sardinia recently lost its oldest citizen. Family members say Antonio Todde died in his sleep early this month. Mr. Todde was 112 years old. It was less than three weeks away from his 113thbirthday. Record-keeping experts say he was the world's oldest man. His long life and that of other very old Sardinians are the subjects of a scientific project called Akea. Luca Deiana of Sassari University is directing the study. He says the name Akea comes from a traditional greeting on Sardinia. It means"health and life for 100 years". Professor Deiana and his team started to collect information for the study in 1997. They identified more than 220 Sardinians who were centenarians--100years old or older. His team required three documents to confirm a person's age. They were a government birth record, a church record and a statement by a close family member. The Akea study has produced two major findings. The first is Sardinia's extremely high number of centenarians. The island had about 135 centenarians for every one million people. In other Western countries, the average is about seventy five centenarians for every one million people. The second major finding is an unusual rate of female to male centenarians. Sardinia has two women centenarians for every male centenarian. In central Sardinia there are equal numbers of female and male centenarians. Studies in other parts of the world have shown a much higher percentage of female centenarians. The Akea study collected information about the health and diet of about 140 of the centenarians. About ninety percent of those in the study agreed to provide blood for scientific testing. The study team hope to identify genetic material in the blood that can be linked to successful aging. Study leaders say there is no single reason why people on Sardinia live so long. They believe the answer is a combination of genetic and environmental conditions.
