Problem: Computer:

The set of arithmetic operations that a particular ALU supports may be limited to addition and subtraction, or might include multiplication, division, trigonometry functions such as sine, cosine, etc., and square roots. Some can only operate on whole numbers (integers) whilst others use floating point to represent real numbers, albeit with limited precision. However, any computer that is capable of performing just the simplest operations can be programmed to break down the more complex operations into simple steps that it can perform. Therefore, any computer can be programmed to perform any arithmetic operationalthough it will take more time to do so if its ALU does not directly support the operation. An ALU may also compare numbers and return boolean truth values (true or false) depending on whether one is equal to, greater than or less than the other ("is 64 greater than 65?").

Some trigonometry functions are what?
---
A: sine, cosine,

Problem: Great power:

All states have a geographic scope of interests, actions, or projected power. This is a crucial factor in distinguishing a great power from a regional power; by definition the scope of a regional power is restricted to its region. It has been suggested that a great power should be possessed of actual influence throughout the scope of the prevailing international system. Arnold J. Toynbee, for example, observes that "Great power may be defined as a political force exerting an effect co-extensive with the widest range of the society in which it operates. The Great powers of 1914 were 'world-powers' because Western society had recently become 'world-wide'."

What should a Western society possess?
---
A: unanswerable

Problem: Videoconferencing:

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 technology has become more widely available and affordable?
---
A: High speed Internet connectivity

Problem: Montevideo:

The Towers Square, is an area of remarkable aesthetic design, intended to be a platform for the development of business activities, art exhibitions, dance and music performances and social place. This square connects the different buildings and towers which comprise the WTC Complex and it is the main access to the complex. The square contains various works of art, notably a sculpture by renowned Uruguayan sculptor Pablo Atchugarry. World Trade Center 4, with 40 floors and 53,500 square metres (576,000 sq ft) of space is under construction as of 2010[update].[citation needed]

How much space is World Trade Center 4 projected to have?
---
A:
53,500 square metres
