Problem: Given the question: I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "Most types of capacitor include a dielectric spacer, which increases their capacitance. These dielectrics are most often insulators. However, low capacitance devices are available with a vacuum between their plates, which allows extremely high voltage operation and low losses. Variable capacitors with their plates open to the atmosphere were commonly used in radio tuning circuits. Later designs use polymer foil dielectric between the moving and stationary plates, with no significant air space between them."?

The answer is:
What are dielectrics used in?

Problem: Given the question: I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "Microsoft began an advertising campaign centered around Windows 8 and its Surface tablet in October 2012, starting with its first television advertisement premiering on October 14, 2012. Microsoft's advertising budget of US$1.51.8 billion was significantly larger than the US$200 million campaign used to promote Windows 95. As part of its campaign, Microsoft set up 34 pop-up stores inside malls (primarily focusing on Surface), provided training for retail employees in partnership with Intel, and collaborated with the electronics store chain Best Buy to design expanded spaces to showcase devices. In an effort to make retail displays of Windows 8 devices more "personal", Microsoft also developed a character known in English-speaking markets as "Allison Brown", whose fictional profile (including personal photos, contacts, and emails) is also featured on demonstration units of Windows 8 devices."?

The answer is:
Which company provided the public with the opportunity to try out Microsoft products hands-on?

Problem: Given the question: I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "Developed countries have people with more resources (housing, food, transportation, water and sewage treatment, hospitals, health care, libraries, books, media, schools, the internet, education, etc.) than most of the world's population. One merely needs to see through travel or the media how many people in the undeveloped countries live to sense this. However, one can also use economic data to gain some insight into this. Yet criticism and blame are common among people in the developed countries."?
++++++++++++++++++++++++++++++++
The answer is:
What main factor separates developed from undeveloped countries.
