Problem: Super Nintendo Entertainment System:

Designed by Masayuki Uemura, the designer of the original Famicom, the Super Famicom was released in Japan on Wednesday, November 21, 1990 for ¥25,000 (US$210). It was an instant success; Nintendo's initial shipment of 300,000 units sold out within hours, and the resulting social disturbance led the Japanese government to ask video game manufacturers to schedule future console releases on weekends. The system's release also gained the attention of the Yakuza, leading to a decision to ship the devices at night to avoid robbery.

What event happened after the Yakuza noticed the sale of the original Famicom?

Problem: Comcast:

Critics noted in 2013 that Tom Wheeler, the head of the FCC, which has to approve the deal, is the former head of both the largest cable lobbying organization, the National Cable & Telecommunications Association, and as largest wireless lobby, CTIA – The Wireless Association. According to Politico, Comcast "donated to almost every member of Congress who has a hand in regulating it." The US Senate Judiciary Committee held a hearing on the deal on April 9, 2014. The House Judiciary Committee planned its own hearing. On March 6, 2014 the United States Department of Justice Antitrust Division confirmed it was investigating the deal. In March 2014, the division's chairman, William Baer, recused himself because he was involved in a prior Comcast NBCUniversal acquisition. Several states' attorneys general have announced support for the federal investigation. On April 24, 2015, Jonathan Sallet, general counsel of the F.C.C., said that he was going to recommend a hearing before an administrative law judge, equivalent to a collapse of the deal.

Who was the general counsel of the FCC in 2015?

Problem: Mandolin:

Many adaptations of the instrument have been done to cater to the special needs of Indian Carnatic music. In Indian classical music and Indian light music, the mandolin, which bears little resemblance to the European mandolin, is usually tuned E-B-E-B. As there is no concept of absolute pitch in Indian classical music, any convenient tuning maintaining these relative pitch intervals between the strings can be used. Another prevalent tuning with these intervals is C-G-C-G, which corresponds to Sa-Pa-Sa-Pa in the Indian carnatic classical music style. This tuning corresponds to the way violins are tuned for carnatic classical music. This type of mandolin is also used in Bhangra, dance music popular in Punjabi culture.

What is another popular madonlin tuning? 
---
A: C-G-C-G


Problem: Nintendo Entertainment System:

In response to these hardware flaws, "Nintendo Authorized Repair Centers" sprang up across the U.S. According to Nintendo, the authorization program was designed to ensure that the machines were properly repaired. Nintendo would ship the necessary replacement parts only to shops that had enrolled in the authorization program. In practice, the authorization process consisted of nothing more than paying a fee to Nintendo for the privilege. In a recent trend, many sites have sprung up to offer Nintendo repair parts, guides, and services that replace those formerly offered by the authorized repair centers.

 What did the repair centers not promise?
