question: Oracle Corporation is a multinational computer technology corporation, headquartered in Redwood Shores, California. The company specializes primarily in developing and marketing database software and technology, cloud engineered systems and enterprise software products particularly its own brands of database management systems. In 2015, Oracle was the second-largest software maker by revenue, after Microsoft.

The company also develops and builds tools for database development and systems of middle-tier software, enterprise resource planning (ERP) software, customer relationship management (CRM) software and supply chain management (SCM) software.

Larry Ellison co-founded Oracle Corporation in 1977 with Bob Miner and Ed Oates under the name Software Development Laboratories (SDL). Ellison took inspiration from the 1970 paper written by Edgar F. Codd on relational database management systems (RDBMS) named "A Relational Model of Data for Large Shared Data Banks." He heard about the IBM System R database from an article in the "IBM Research Journal" provided by Oates. Also derived from Codd's theories, Ellison wanted to make Oracle's product compatible with System R, but failed to do so as IBM kept the error codes for their DBMS a secret. SDL changed its name to Relational Software, Inc (RSI) in 1979, then again to Oracle Systems Corporation in 1982, to align itself more closely with its flagship product Oracle Database. At this stage Bob Miner served as the company's senior programmer. On March 12, 1986, the company had its initial public offering. In 1995, Oracle Systems Corporation changed its name to Oracle Corporation, officially named Oracle, but sometimes referred to as Oracle Corporation, the name of the holding company. Part of Oracle Corporation's early success arose from using the C programming language to implement its products. This eased porting to different operating systems (most of which support C).

Humans have sewn by hand for thousands of years. It was said that the first thread was made from animal muscle and sinew . And the earliest needles were made from bones. Since those early days, many people have been involved in the process of developing a machine that could do the same thing more quickly and with greater efficiency.

Charles Wiesenthal, who was born in Germany, designed and received a patent on a double-pointed needle that eliminated the need to turn the needle around with each stitch in England in 1755. Other inventors of that time tried to develop a functional sewing machine, but each design had at least one serious imperfection.

Frenchman Barthelemy Thimonnier finally engineered a machine that really worked. However, he was nearly killed by a group of angry tailors when they burned down his garment factory. They feared that they would lose their jobs to the machine.

American inventor Elias Howe, born on July 9, 1819, was awarded a patent for a method of sewing that used thread from two different sources. Howe's machine had a needle with an eye at the point, and it used the two threads to make a special stitch called a lockstitch. However, Howe faced difficulty in finding buyers for his machines in America. In frustration, he traveled to England to try to sell his invention there. When he finally returned home, he found that dozens of manufacturers were adapting his discovery for use in their own sewing machines.

Isaac Singer, another American inventor, was also a manufacturer who made improvements to the design of sewing machines. He invented an up-and-down-motion mechanism that replaced the side-to-side machines. He also developed a foot treadle to power his machine. This improvement left the sewer's hands free. Undoubtedly, it was a huge improvement of the hand-cranked machine of the past. Soon the Singer sewing machine achieved more fame than the others for it was more practical. It could be adapted to home use and it could be bought on hire-purchase. The Singer sewing machine became the first home appliance, and the Singer company became one of the first American multinationals.

However, Singer used the same method to create a lockstitch that Howe had already patented. As a result, Howe accused him of patent infringement . Of course, Elias Howe won the court case, and Singer was ordered to pay Howe royalties . In the end, Howe became a millionaire, not by manufacturing the sewing machine, but by receiving royalty payments for his invention. What are the answers to this following set of questions: 1. What was Isaac Singer's occupation?
2. What product did he improve upon?
3. And who was Elias Howe?
4. When was his birthdate?
5. What do these two men have in common regarding their nationality?

7. For how long has it been happening?
8. And how did they do it?
9. What was different about what these inventors were creating?

Answer: 1. inventor

4. July 9, 1819
5. Both are from America

7. thousands of years
8. used bones

input: Make use of the article to answer the questions. Washington (CNN) -- The United States is watching closely to the see the ultimate fate of the most powerful man in Pakistan, Gen. Ashfaq Parvez Kayani, the Pakistani army's chief of staff.

Pressured by Washington to crack down on terrorists at the same time he was kept in the dark about the U.S. raid to kill Osama bin Laden, Kayani "is facing more vocal and strident criticism than he has in the past," a senior U.S. military official told CNN. "We really think he is coming under increased scrutiny by junior and mid-grade officers."

This is the type of scrutiny senior Pakistani generals like Kayani are "not accustomed to facing," the official said.

Criticism of Kayani inside Pakistan had grown in recent months as he became close to the Obama administration and the Pentagon. But in the wake of the U.S. military raid into Pakistan to kill bin Laden, the criticism has increased from an officer corps furious that U.S. troops invaded Pakistan's territory without the Pakistani military, and especially Kayani, being consulted.

Adm. Michael Mullen, chairman of the U.S. Joint Chiefs of Staff, is one of Kayani's closest professional and personal allies, having met with him many times in the past several years.

"Mullen does consider him a friend," said the admiral's spokesman, Capt John Kirby. "That doesn't mean there aren't still disagreements. It doesn't mean Kayani doesn't feel betrayed."

U.S. officials are closely watching a group known as the "11 corps commanders," the senior Pakistani generals hand-picked by Kayani to command. Keeping their loyalty will be crucial for Kayani to keep his job. 1. Is this scrutiny something Kayani is used to?
2. who is Kayani?
3. what is his full name?
4. who is one of his cloest allies?
5. and who is he?
6. do they ever argue?
7. what is washington pressuring Kayani to do?
8. what secret was kept from him?
9. what was the point of the raid?
