Passage Two
In a small liboratory at the Medical University of South Carolina, Dr. Vladimir Mironov has been working for a decade to grow meat. A developmental biologist and tissue engineer, Dr. Mironov, is one of only a few scientists worldwide involved in bioengineering 'cultured' meat.
It's a product he believes could help solve future global food crises resulting from shrinking amounts of land available for growing meat the old-fashioned way.
“Growth of cultured meat is also under way in the Netherlands”, Mironov told Reuters in an interview, “but in the United States, it is science in search of funding and demand.”
The new National Institute of Food and Agriculture won't fund it, the National Institutes of Health won't fund it, and the NASA funded it only briefly, Mironov said.
"It's classic disruptive technology," Mironov said. "Bringing any new technology on the market, on average, costs $1 billion. We don't even have $1 million."
Director of the Advanced Tissue Biofabrication Center in the Department of Regenerative Medicine and Cell Biology at the medical university, Mironov now primarily conducts research on tissue engineering, or growing, of human organs.
"There's an unpleasant factor when people find out meat is grown in a lab. They don't like to associate technology with food," said Nicholas Genovese, a visiting scholar in cancer cell biology.
"But there are a lot of products that we eat today that are considered natural that are produced in a similar manner," Genovese said.
30. What does Dr. Mironov think of bioengineering cultured meat?
31. What does Dr. Mironov say about the funding for their research?
32. What does Nicholas Genovese say about a lot of products we eat today?
Passage Three
Bernard Jackson is a free man today, but he has many bitter memories. Jackson spent five years in prison after a jury wrongly convicted him of raping two women. At Jackson's trial, although two witnesses testified that Jackson was with them in another location at the times of the crimes, he was convicted anyway. Why? The jury believed the testimony of the two victims, who positively identified Jackson as the man who has attacked them. The court eventually freed Jackson after the police found the man who had really committed the crimes. Jackson was similar in appearance to the guilty man. The two women has made a mistake in identity. As a result, Jackson has lost five years of his life.
The two women in this case were eyewitnesses. They clearly saw the man who attacked them, yet they mistakenly identified an innocent person. Similar incidents have occurred before. Eyewitnesses to other crimes have identified the wrong person in a police lineup or in photographs.
Many factors influence the accuracy of eyewitness testimony. For instance, witnesses sometimes see photographs of several suspects before they try to identify the person they saw in a lineup of people. They can become confused by seeing many photographs or similar faces. The number of people in the lineup, and whether it is a live lineup or a photograph, may also affect a witness's decision. People sometimes have difficulty identifying people of other races. The questions the police ask witnesses also have an effect on them.
Question 33: What do we learn about Bernard Jackson?
Question 34: What led directly to Jackson’s sentence?
Question 35: What lesson do we learn from Jackson’s case?
