(Financial Times) -- The increasing amount of personal information that can been gleaned by computer programs that track how people use Facebook has been revealed by an extensive academic study. Such programmes can discern undisclosed private information such as Facebook users' sexuality, drug-use habits and even whether their parents separated when they were young, according to the study by Cambridge university academics. In one of the biggest studies of its kind, scientists from the university's psychometrics team and a Microsoft-funded research centre analysed data from 58,000 Facebook users to predict traits and other information that were not provided in their profiles. The algorithms were 88 per cent accurate in predicting male sexual orientation, 95 per cent for race and 80 per cent for religion and political leanings. Personality types and emotional stability were also predicted with accuracy ranging from 62-75 per cent. Facebook declined to comment. The study highlights growing concerns about social networks and how data trails can be mined for sensitive information, even when people attempt to keep information about themselves private. Less than 5 per cent of users predicted to be gay, for example, were connected with explicitly gay groups. Michal Kosinksi, one of the report's authors, told the Financial Times that the university's techniques could easily be replicated by companies to infer personal attributes a person did not wish to share, such as sexual orientation or political views: "We used very simple and generic methods. Marketing companies and internet companies could spend much more time and resources, and hence get much higher accuracy than we did." Last week , the EU agreed to water down proposals for a radical overhaul of data privacy regulation. The move reflects governments' reluctance to impede internet businesses that might spur economic growth, and follows fierce lobbying from technology companies including Facebook and Google. Personal data has become big business. Wonga, the UK online lender, makes credit judgments within seconds based on thousands of pieces of information, including an applicant's Facebook profile. Tesco, the supermarket chain, this month started to use its customers' shopping histories to sell targeted online advertising. The report also revealed some unexpected correlations -- such as people who liked 'curly fries' having higher IQs, while those who like Facebook's "Sliding on Floors With Your Socks On" page were unlikely to use drugs.

Question: "Has Facebook commented on the ability of computer programs that track how people use Facebook to discern undisclosed private information?"

Gravitational Potential Energy is affected by position. Like the leaves on trees, anything that is raised up has the potential to fall. It has potential energy. You can see examples of people with gravitational potential energy in 1.5 Figure below. Gravitational potential energy depends on two things. It depends on its weight, because a large falling rock can do more damage than a leaf falling from a tree. It also depends on its height above the ground. Like the skateboarder, the higher the ramp, the faster he will be going when he reaches the bottom. Like all energy, gravitational potential energy has the ability to do work. In this case, weight has the potential to deliver a force. More important for us is that it has the ability to cause change. What kind of change you may ask? Gravitational potential energy has the ability to cause motion.

Question: "Name two examples of the effect of gravitational potential energy that are given in the paragraph."

Answer: "Leave on tress"

Response: yes

Marsha loves playing with her noodle friend. She had it for a long time so it is now a dark brown color. When her mom first made it, it was white. The night she met her noodle friend was spaghetti night. Marsha's favorite dinner was spaghetti, which happened to be every Tuesday night. On one Tuesday, a piece of spaghetti fell on the kitchen floor. To Marsha, it looked like a stick man so she kept him. She named her new noodle friend Joey and took him everywhere she went. Sometimes Joey gets a little dried out so Marsha's mom told her to soak him in water every few days. There were a couple times that the family dog, Mika, has tried to take Joey from Marsha and eat him! So from now on, Marsha takes extra special care to make sure Joey is safe and sound at all times. During the day she keeps him in a plastic bag in her pocket. At night, she puts him under her pillow. She loves Joey and wants to always be friends with him.

Question: "When a noodle fell on the floor, what did it look like to Marsha?"

Answer: "A string"

On a day it celebrated 50 years of giving free legal advice, Southern Arizona Legal Aid announced it has received two grants totaling more than $7 million. One of the grants includes the creation of a Web site with legal advice for the poor. A three-year grant worth $6.6 million and a separate technology grant were announced at a press conference and dinner held Thursday at Evo. A. DeConcini Federal Courthouse, 405 W. Congress St. Deconcini was one of the organization's early board members. Thursday's celebration was the first public even held at the courthouse. About 100 members of the legal community attended, including state Attorney General Janet Napolitano and Arizona Supreme Court Justice Thomas Zlaket. Both grants come from the Legal Services., a private, nonprofit corporation established by Congress in 1974 to offer poor people equal access to the justice system. It's funded through congressional appropriation. The $6.6 million grant will pay for staffing operations. The Web site, which will be created with a $50,000 grant, is intended to offer legal advice to poor people across Arizona, said Paul Julian, chief executive officer of Southern Arizona Legal Aid. He said he wants every poor person in Arizona to have legal help. "This is another step in trying to realize that. We feel like we do a pretty good job of helping people who find us," Julian said. Julian said that though most people do not own computers, they can still access them at libraries, schools, and courthouses. He said the Web site will help bridge the "digital divide" that keeps the poor from using the Internet as a resource. Southern Arizona Legal Aid was founded in 1951 as the Legal Aid Society of the Pima County Bar Association. It offered free legal advice on civil matters including disputes in small claims court, divorce proceedings and obtaining Social Security benefits. Charles Ares, a member of the board of directors in the 1950s, said the office was kind of a charity operation.

Question: "Who will the Web site benefit?"
