【正确答案】 A

【答案解析】[听力原文] A super attendant of the city's municipal building, Delia Sadorno, was responsible for presenting its new security plan to the public. City employees, citizens and reporters gathered in the hall to hear her describe the plan. After outlining the main points she would cover, she assured the audience that she would be happy to answer questions at the end of her presentation. Delia realized the plan was expensive and potentially controversial. So she was not surprised to see a number of hands go up as soon as she finished speaking. An employee asked, 'Would the new system create long lines to get into the building like the lines at airport security checks?' Delia had anticipated this question and had an answer ready. After repeating the question, she explained that the sufficient number of security guards would be working at peak hours to speed things along. The next question was more confrontational. 'Where will the money come from to pay for all of this?' The journalists who asked the question seemed hostile. But Delia was careful not to adopt a defensive tone. She stated that the money would come from the city's general budget. 'I know these are tight times', she added, 'but everyone agrees on the importance of safeguarding our employees and members of the public who come into the building.' Near the end of the 25 minutes she had said, Delia said she would take two more questions. When those were finished, she concluded the session with a brief restatement of how the new system would improve security and peace of mind in the municipal building. What is the focus of Delia Sadorno's presentation?
