Q: In August 1836, two real estate entrepreneurs—Augustus Chapman Allen and John Kirby Allen—from New York, purchased 6,642 acres (26.88 km2) of land along Buffalo Bayou with the intent of founding a city. The Allen brothers decided to name the city after Sam Houston, the popular general at the Battle of San Jacinto, who was elected President of Texas in September 1836. The great majority of slaves in Texas came with their owners from the older slave states. Sizable numbers, however, came through the domestic slave trade. New Orleans was the center of this trade in the Deep South, but there were slave dealers in Houston. Thousands of enslaved African-Americans lived near the city before the Civil War. Many of them near the city worked on sugar and cotton plantations, while most of those in the city limits had domestic and artisan jobs. In 1860 forty-nine percent of the city's population was enslaved. A few slaves, perhaps as many as 2,000 between 1835 and 1865, came through the illegal African trade. Post-war Texas grew rapidly as migrants poured into the cotton lands of the state. They also brought or purchased enslaved African Americans, whose numbers nearly tripled in the state from 1850 to 1860, from 58,000 to 182,566.

input: Make use of the article to answer the questions. Two good friends, Sam and Jason, met with a car accident on their way home one night. The next morning, Sam woke up blind. His legs were broken. The doctor, Mr Lee was standing by his bed, looking at him with a thoughtful expression. When he saw Sam awake, he asked, "How are you feeling, Sam?" Sam smiled and said, "Not bad, Doctor. Thank you for doing the operation ." Mr Lee was moved by Sam. When he was leaving, Sam said, "Please don't tell Jason about it." "... OK." Mr Lee replied. 

Months later when Jason's wounds _ , Sam was still very sick. Neither could he see or walk. What he could do was just stay in his wheelchair all day long. At first, Jason stayed with him for a few days. But days later, Jason felt very discouraged and embarrassed to spend time staying with a disabled man like Sam. So he went to see Sam less and less. He made new friends. From then on, he didn't go to visit Sam any more. Sam didn't have any family or friends other than Jason. He felt very sad. 

Things went from bad to worse. Sam died a year later. When Jason came, Mr Lee gave a letter to him. It was from Sam. In the letter Sam said, "Dear Jason, I am disabled. But I want you to be a healthy man. So I gave my eyes to you so that you can enjoy life as a healthy man. Now you have new friends. I'm glad to see that you are as healthy and happy as usual. I'm glad you live a happy life. You are always my best friend ... ... Sam". When he finished reading the letter Mr Lee said, "I have promised that I will keep this a secret until Sam is gone.

Scientists in Argentina have created the world's first cow to own two human genes that will enable it to produce human-like milk, which is matchless up to now. It is a breakthrough in the area of clone. 

Genetic engineering was used to introduce the "mothers' milk" genes into the animal before birth, according to the National Institute of Agribusiness Technology in Buenos Aires. 

As an adult, the cloned cow "will produce milk that is similar to humans" in what will prove "a development of great importance for the nutrition of infants", it said in a statement. 

"The cloned cow, named Rosita ISA, is the first one born in the world that owns two human genes that contain the proteins present in human milk," the statement said. 

In April, scientists in China published details of research showing that they had created GM Holstein dairy cows which produced milk containing proteins found in human breast milk. 

But the Argentine team says the Chinese only introduced one human gene, whereas their research involved two genes meaning the milk will more closely resemble that of humans. 

Rosita ISA was born on April 6 and was delivered by Caesarean section because she weighed around 100 pounds, roughly twice the normal weight of Jersey cows. 

Adrian Mutto, from the National University of San Martin said "Our goal was to raise nutritional value of cows' milk by adding two human genes, the protein lactoferrin and lysozyme, which can provide newly-born babies with anti-bacterial and anti-viral protection." 

Cristina Kirchner, President of Argentina, said that the scientific institute "makes all proud." She also revealed that she had rejected the "honor" of having the cow named after her. "They came to tell me that the name is Cristina, but what woman would like to have a cow named after her? It appeared to me to be more appropriate to call it Rosita." What are the answers to this following set of questions: 1. This cow has human what?
2. Where's it at?
3. What does it produce?
4. What was used to get the genes into the cow?
5. According to who?
