Problem: Northwestern University:

Many students are involved in community service in one form or another. Annual events include Dance Marathon, a thirty-hour event that raised more than a million dollars for charity in 2011; and Project Pumpkin, a Halloween celebration hosted by the Northwestern Community Development Corps (NCDC) to which more than 800 local children are invited for an afternoon of games and sweets. NCDC's work is to connect hundreds of student volunteers to some twenty volunteer sites in Evanston and Chicago throughout the year. Many students have assisted with the Special Olympics and have taken alternative spring break trips to hundreds of service sites across the United States. Northwestern students also participate in the Freshman Urban Program, a program for students interested in community service. A large and growing number of students participate in the university's Global Engagement Summer Institute (GESI), a group service-learning expedition in Asia, Africa, or Latin America, in conjunction with the Foundation for Sustainable Development. Several internationally recognized non-profit organizations have originated at Northwestern including the World Health Imaging, Informatics and Telemedicine Alliance, a spin-off from an engineering student's honors thesis.

What is the name of the Halloween celebration to which over 700 local children are invited?

Problem: Symbiosis:

One of the most spectacular examples of obligate mutualism is between the siboglinid tube worms and symbiotic bacteria that live at hydrothermal vents and cold seeps. The worm has no digestive tract and is wholly reliant on its internal symbionts for nutrition. The bacteria oxidize either hydrogen sulfide or methane, which the host supplies to them. These worms were discovered in the late 1980s at the hydrothermal vents near the Galapagos Islands and have since been found at deep-sea hydrothermal vents and cold seeps in all of the world's oceans.

When were the worms found?
---
A: the late 1980s


Problem: Kanye West:

On November 10, 2007, at approximately 7:35 pm, paramedics responding to an emergency call transported West's mother, Donda West, to the nearby Centinela Freeman Hospital in Marina del Rey, California. She was unresponsive in the emergency room, and after resuscitation attempts, doctors pronounced her dead at approximately 8:30 pm, at age 58. The Los Angeles County coroner's office said in January 2008 that West had died of heart disease while suffering "multiple post-operative factors" after plastic surgery. She had undergone liposuction and breast reduction. Beverly Hills plastic surgeon Andre Aboolian had refused to do the surgery because West had a health condition that placed her at risk for a heart attack. Aboolian referred her to an internist to investigate her cardiac issue. She never met with the doctor recommended by Aboolian and had the procedures performed by a third doctor, Jan Adams.

What condition along with complications for the plastic surgery caused the death of Donda West?
---
A: heart disease


Problem: Software testing:

Grey-box testing (American spelling: gray-box testing) involves having knowledge of internal data structures and algorithms for purposes of designing tests, while executing those tests at the user, or black-box level. The tester is not required to have full access to the software's source code.[not in citation given] Manipulating input data and formatting output do not qualify as grey-box, because the input and output are clearly outside of the "black box" that we are calling the system under test. This distinction is particularly important when conducting integration testing between two modules of code written by two different developers, where only the interfaces are exposed for test.

The tester is required to have full access to what piece of information?
