Problem: Database:

In recent years there was a high demand for massively distributed databases with high partition tolerance but according to the CAP theorem it is impossible for a distributed system to simultaneously provide consistency, availability and partition tolerance guarantees. A distributed system can satisfy any two of these guarantees at the same time, but not all three. For that reason many NoSQL databases are using what is called eventual consistency to provide both availability and partition tolerance guarantees with a reduced level of data consistency.

What can satisfy all guarantees at the same time?

The race was the most expensive for Congress in the country that year and four days before the general election, Durkin withdrew and endorsed Cronin, hoping to see Kerry defeated. The week before, a poll had put Kerry 10 points ahead of Cronin, with Dukin on 13%. In the final days of the campaign, Kerry sensed that it was "slipping away" and Cronin emerged victorious by 110,970 votes (53.45%) to Kerry's 92,847 (44.72%). After his defeat, Kerry lamented in a letter to supporters that "for two solid weeks, [The Sun] called me un-American, New Left antiwar agitator, unpatriotic, and labeled me every other 'un-' and 'anti-' that they could find. It's hard to believe that one newspaper could be so powerful, but they were." He later felt that his failure to respond directly to The Sun's attacks cost him the race.
How many votes did Cronin get against Kerry?
A: 110,970

Question: As of 2009, dial up, wireless and satellite services were available. Dial up internet services in Somalia were among the fastest growing on the continent, with an annual landline growth rate of over 12.5%. The increase in usage was largely due to innovative policy initiatives adopted by the various Somali telecom operators, including free local in-town calls, a flat rate of $10 per month for unlimited calls, a low charge of $0.005 per minute for Internet connections, and a one-time connection fee of $50. Global Internet Company, a firm jointly owned by the major Somali telecommunication networks Hormuud Telecom, Telcom Somalia and Nationlink, was the country's largest ISP. It was at the time the only provider of dial up services in Somalia's south-central regions. In the northern Puntland and Somaliland regions, online networks offered internet dial up services to their own group of subscribers. Among these firms was Golis Telecom Somalia in the northeast and Telesom in the northwest.

Before emerging as a pop star, Madonna has spent her early years in rock music alongside her bands, Breakfast Club and Emmy. While performing with Emmy, Madonna recorded about 12-14 songs which resemble the punk rock of that period. Her early rock roots also can be found on the demo album Pre-Madonna. Stephen Thomas Erlewine noted that with her self-titled debut album, Madonna began her career as a disco diva, in an era that did not have any such divas to speak of. In the beginning of the '80's, disco was an anathema to the mainstream pop, and according to Erlewine, Madonna had a huge role in popularizing dance music as mainstream music. The album's songs reveal several key trends that have continued to define her success, including a strong dance-based idiom, catchy hooks, highly polished arrangements and Madonna's own vocal style. Her second album, Like a Virgin (1984), foreshadowed several trends in her later works. It contained references to classical works (pizzicato synthesizer line that opens "Angel"); potential negative reaction from social groups ("Dress You Up" was blacklisted by the Parents Music Resource Center); and retro styles ("Shoo-Bee-Doo", Madonna's homage to Motown).
What is Madonna's second album?
A:
Like a Virgin
