Article: For a 400-year-old art form, opera had a bad fame: overweight actresses singing the words which were hard to understand in one of those romance languages you were supposed to learn in high school. And with tickets costing as much as $145 a performance, opera goers also had a certain appearance in people's mind: rich, well-dressed and old.[:] But now opera companies around the country are loosening their ties and kicking off their shoes in an attempt to keep opera alive and take it to a younger and not so wealthy audience. Opera producers have found that to attract this crowd, they need to make the opera closer to common people. Because young people don't or won't come to the opera, companies are bringing the opera to them, giving performances in such unusual places as parks, libraries and public schools. The Houston Grand Opera's choice is the public library, where it performs "mobile operas" shortened versions  of child-friendly operas. This summer's production is Hansel & Gretel. By performing smaller versions of large productions, producers are able to make people interested while keeping costs at a reasonable level. The San Francisco Opera, which will be celebrating its 75th anniversary this year, is staging Cinderella free of charge, keeping costs down by employing students from its Young Artists' Training Program. 
 Answer: Young people are not interested in opera.
Which is the main idea of this passage?

Article: Instead of a normal court hearing, the trial on Wednesday appeared more like a prepared drama. Hundreds of reporters waited outside the court, in the hope of learning "shocking" information about the case, which includes well-known military singer Li Shuangjiang's son, who gang-raped a woman with another four men on February. The case was not a public hearing because it includes teenagers, whose privacy must be protected under law, but many details had been exposed by the lawyers before the trial. Lawyers of all five suspects and the woman's lawyer made a lot of debate on the Internet before the trial, making the case more confused. Wu Ming'an, a law professor from the China University of Political Science and Law, said it was a pity to see such a "performance" by the lawyers. "It can be understood that the two parties freely spoke their opinions, but it's not professional or wise to see lawyers do the same," Wu said. "Instead, the lawyers should guide and persuade their clients  to calm down, especially for such a non-public and sensitive case." China has no clear rule to manage lawyers' behavior before trials, "but it should be general knowledge that the lawyers of the two sides cannot _ too many details, particularly in a case that includes teenagers", Wu added. Yi Shenghua, a lawyer who has been following the case, said it does more harm than good to both parties for such detailed information to be exposed before the trial. "It's OK for lawyers to speak, but what is said must be reasonable and legal. Although judgments should not be affected by public opinion, it's hard for them not to be," he said, suggesting judicial authorities should speak out if the case goes wrongly. Trials must be conducted based on evidence, while lawyers should protect their clients' rights instead of adding fuel to the flames, Yi said. In my eyes, the most important aspect of the case, lies in how to make lawyers do their work more professionally and reasonably. 
 Answer: Because many details had already been exposed before the trial.
Why was the case not a public hearing?

Article: It is pretty much a one-way street.While it may"be common for university researchers to try their luck in the commercial world,there is very little traffic in the opposite direction.Pay has always been the biggest _ ,as people with families often feel they cannot afford the drop in salary when moving to a university job.For some industrial scientists,however, the attractions of academia outweigh any financial considerations. Helen Lee took a 70%cut in salary when she moved from a senior post in Abbott Laboratories to a medical department at the University of Cambridge.Her main reason for returning to academia halfway was to take advantage of the greater freedom to choose research questions.Some areas of research have few chances of a commercial return,and Lee's is one of them. The powerful effect of a salary cut is probably less severe for a scientist in the early stages of an occupation.Guy Grant,now a research associate at the Unilever Centre for Molecular Informatics at the University of Cambridge,spent two years working for a medicine company before returning to university as a post-doctoral researcher.He took a 30%salary cut but felt it worthwhile for the greater intellectual opportunities. Higher up the ladder,where a pay cut is usually more significant,the demand for scientists with a wealth of experience in industry is forcing universities to make the transition to academia more attractive,according to Lee.Industrial scientists tend to receive training that academics do not,such as how to build a multidisciplinary team,manage budgets and negotiate contracts .They are also well placed to bring something extra to the teaching side of an academic role that will help students get a job when they graduate,says Lee,perhaps experience in manufacturing practice or product development."Only a small number of undergraduates will continue in an academic occupation.So someone leaving university who already has the skills needed to work in an industrial lab has far more potential in the job market than someone who has spent a11 their time on a narrow research project." 
 Answer: Her research interests.

What was Helen Lee's major consideration when she changed her j ob halfway?
