Problem: Beyoncé:

Beyoncé has worked with Pepsi since 2002, and in 2004 appeared in a Gladiator-themed commercial with Britney Spears, Pink, and Enrique Iglesias. In 2012, Beyoncé signed a $50 million deal to endorse Pepsi. The Center for Science in the Public Interest (CSPINET) wrote Beyoncé an open letter asking her to reconsider the deal because of the unhealthiness of the product and to donate the proceeds to a medical organisation. Nevertheless, NetBase found that Beyoncé's campaign was the most talked about endorsement in April 2013, with a 70 per cent positive audience response to the commercial and print ads.

How much did Beyoncé get for a deal with a soft drink company in 2012?

A: $50 million


Problem: High speed Internet connectivity has become more widely available at a reasonable cost and the cost of video capture and display technology has decreased. Consequently, personal videoconferencing systems based on a webcam, personal computer system, software compression and broadband Internet connectivity have become affordable to the general public. Also, the hardware used for this technology has continued to improve in quality, and prices have dropped dramatically. The availability of freeware (often as part of chat programs) has made software based videoconferencing accessible to many.
What has become more available as the availability of freeware has decreased?

Context and question: The Karabakh war ended after a Russian-brokered cease-fire was put in place in 1994. The war was a success for the Karabakh Armenian forces who managed to capture 16% of Azerbaijan's internationally recognised territory including Nagorno-Karabakh itself. Since then, Armenia and Azerbaijan have held peace talks, mediated by the Organisation for Security and Co-operation in Europe (OSCE). The status of Karabakh has yet to be determined. The economies of both countries have been hurt in the absence of a complete resolution and Armenia's borders with Turkey and Azerbaijan remain closed. By the time both Azerbaijan and Armenia had finally agreed to a ceasefire in 1994, an estimated 30,000 people had been killed and over a million had been displaced.
How many people died as a result of the fighting betwen Armenia and Azerbaijan?
Answer: 30,000


Question: The infinitive form ends in t (archaically, ti). It is the form found in dictionaries and the form that follows auxiliary verbs (for example, můžu tě slyšet—"I can hear you"). Czech verbs have three grammatical moods: indicative, imperative and conditional. The imperative mood adds specific endings for each of three person (or number) categories: -Ø/-i/-ej for second-person singular, -te/-ete/-ejte for second-person plural and -me/-eme/-ejme for first-person plural. The conditional mood is formed with a particle after the past-tense verb. This mood indicates possible events, expressed in English as "I would" or "I wish".
