Problem: Guinea-Bissau:

After several years of economic downturn and political instability, in 1997, Guinea-Bissau entered the CFA franc monetary system, bringing about some internal monetary stability. The civil war that took place in 1998 and 1999, and a military coup in September 2003 again disrupted economic activity, leaving a substantial part of the economic and social infrastructure in ruins and intensifying the already widespread poverty. Following the parliamentary elections in March 2004 and presidential elections in July 2005, the country is trying to recover from the long period of instability, despite a still-fragile political situation.

When was there a military coup in Guinea-Bissau?
---
A: September 2003

Context and question: The pits and lands themselves do not directly represent the zeros and ones of binary data. Instead, non-return-to-zero, inverted encoding is used: a change from pit to land or land to pit indicates a one, while no change indicates a series of zeros. There must be at least two and no more than ten zeros between each one, which is defined by the length of the pit. This in turn is decoded by reversing the eight-to-fourteen modulation used in mastering the disc, and then reversing the cross-interleaved ReedSolomon coding, finally revealing the raw data stored on the disc. These encoding techniques (defined in the Red Book) were originally designed for CD Digital Audio, but they later became a standard for almost all CD formats (such as CD-ROM).
What does a land represent?
Answer: unanswerable

Problem: Computer security:

In 2013 and 2014, a Russian/Ukrainian hacking ring known as "Rescator" broke into Target Corporation computers in 2013, stealing roughly 40 million credit cards, and then Home Depot computers in 2014, stealing between 53 and 56 million credit card numbers. Warnings were delivered at both corporations, but ignored; physical security breaches using self checkout machines are believed to have played a large role. "The malware utilized is absolutely unsophisticated and uninteresting," says Jim Walter, director of threat intelligence operations at security technology company McAfee meaning that the heists could have easily been stopped by existing antivirus software had administrators responded to the warnings. The size of the thefts has resulted in major attention from state and Federal United States authorities and the investigation is ongoing.

How many credit card numbers were stole from Home Depot in 2014?
---
A:
between 53 and 56 million
