Read the following article and select the best answer. Article: For many blind people, computers are inaccessible. It can cost $1,000 to purchase "screen reader" software, but two blind computer programmers from Australia have solved this problem. Queensland University of Technology (QUT) graduate James Teh and business partner Michael Curran developed a free, open-source program, called NVDA, which provides a voice to read the words on a computer screen as the cursor moves over them. NVDA won the blind inventors an award in the grand final program of the ABC's New Inventors, which aired on September 23. They took home the award for an invention that "might make a real difference to people's lives or the environment." "A sighted person takes for granted that they can sit down at any computer and use it," Mr Teh said. "We really are in the information age -- everything is online these days. So access to computers for the blind is very important, which is why we wanted our software to be free." Mr Teh, who majored in software engineering at QUT, said blind students typically didn't have the money to purchase "screen reader" technology, at the time in their life when they most needed it. Now NVDA could be downloaded on to anyone's personal computer free of charge. "It can also be copied to a USB stick, which can be used on any PC at school or university, with no installation required," he said. Mr Teh and Mr Curran have drawn on their own experience as blind computer users to develop a product which has some unique features. For example, as the mouse moves up and down the screen, a sound becomes higher and lower to let you know where the cursor is located. NVDA has been translated into 27 languages, thanks to volunteer translators. To date, there have been over 50,000 downloads. Mr Teh and Mr Curran have been working on the project since 2006. They worked on their product without any pay for two years. When Mozilla offered some funding in 2008, Mr Teh was able to quit his day job and work full-time developing NVDA. Question: NVDA won an award in the program of the ABC's New Inventors because it _ . - causes no harm to the environment - influences people' s lives - is aiming at blind people - is easy to use
influences people' s lives

Read the following article and select the best answer. Article: Researchers invited 79 people between the ages of 18 and 50 years old who had been diagnosed with depression. 33 of the participants were offered 20 music therapy sessions, in addition to their usual treatment for depression. The other 46 participants received stan dard treatment, and acted as the control group. The one-on-one music therapy sessions each lasted 60 minutes and took place twice a week. Trained music therapists helped each participant to improvise music. On average, each participant attended 18 music therapy sessions. 29 individuals (88 percent) attended at least 15 sessions. The participants in both groups were followed up at three and six months and assessed forsymptoms of depression and anxiety. In the final analysis, researchers discovered that af ter three months of participation, individuals who received music therapy showed greatly fewer symptoms of depression and anxiety, and scored better on general functioning. Although improvements still remained after six months, the difference between the groups was no longer statistically significant. Co-researcher Christian Gold, Ph.D., explained the study findings: "Our trial has shown that music therapy, when added to standard care including medication, psychotherapy and counseling , helps people to improve their levels of depression and anxiety. Music therapy has specific qualities that allow people to express themselves and interact in a non-verbal way - even when they cannot find the words to describe their inner experiences." Given the success of the study, researchers say it needs to be repeated with a larger sample of people, and that further research is needed to assess the cost-effectiveness of such therapy. Outside experts believe this study shows that music ther apy is an effective addition to traditional therapy and improves outcomes. Mike Crawford, M.D., said, "This is a high-quality randomized trial of music therapy specifically for depression, and the results suggest that it can improve the mood and general functioning of...
