Here is a question about this article: For example, in order to meet the expectations for good color rendering in retail applications, research suggests using the well-established CRI along with another metric called gamut area index (GAI). GAI represents the relative separation of object colors illuminated by a light source; the greater the GAI, the greater the apparent saturation or vividness of the object colors. As a result, light sources which balance both CRI and GAI are generally preferred over ones that have only high CRI or only high GAI.
What is the answer to this question: What does GAI stand for?
****
So... gamut area index


The problem: Answer a question about this article:
Dominic's search for a close relationship with God was determined and unceasing. He rarely spoke, so little of his interior life is known. What is known about it comes from accounts written by people near to him. St. Cecilia remembered him as cheerful, charitable and full of unceasing vigor. From a number of accounts, singing was apparently one of Dominic's great delights. Dominic practiced self-scourging and would mortify himself as he prayed alone in the chapel at night for 'poor sinners.' He owned a single habit, refused to carry money, and would allow no one to serve him.
What did Dominic refuse to do?
****
The answer: carry money


Problem: Please answer a question about the following article about London:
By the 11th century, London was beyond all comparison the largest town in England. Westminster Abbey, rebuilt in the Romanesque style by King Edward the Confessor, was one of the grandest churches in Europe. Winchester had previously been the capital of Anglo-Saxon England, but from this time on, London became the main forum for foreign traders and the base for defence in time of war. In the view of Frank Stenton: "It had the resources, and it was rapidly developing the dignity and the political self-consciousness appropriate to a national capital."
By which century had London started becoming a prominent capital city?
A: the 11th century


Question: Read this and answer the question

YouTube relies on its users to flag the content of videos as inappropriate, and a YouTube employee will view a flagged video to determine whether it violates the site's terms of service. In July 2008, the Culture and Media Committee of the House of Commons of the United Kingdom stated that it was "unimpressed" with YouTube's system for policing its videos, and argued that "proactive review of content should be standard practice for sites hosting user-generated content". YouTube responded by stating:

Who of the house of commons spoke out on youtube's policies?
Answer: the Culture and Media Committee


Problem: In China, which uses simplified Chinese characters, the Xiàndài Hànyǔ Chángyòng Zìbiǎo (现代汉语常用字表, Chart of Common Characters of Modern Chinese) lists 2,500 common characters and 1,000 less-than-common characters, while the Xiàndài Hànyǔ Tōngyòng Zìbiǎo (现代汉语通用字表, Chart of Generally Utilized Characters of Modern Chinese) lists 7,000 characters, including the 3,500 characters already listed above. GB2312, an early version of the national encoding standard used in the People's Republic of China, has 6,763 code points. GB18030, the modern, mandatory standard, has a much higher number. The New Hànyǔ Shuǐpíng Kǎoshì (汉语水平考试, Chinese Proficiency Test) covers approximately 2,600 characters at its highest level (level six).
What lists 2,500 common characters?
The answer is the following: Chart of Common Characters of Modern Chinese


Input: Article: Reflection of the original signal also occurs when it hits an extended conductive surface, in a fashion similar to a mirror. This effect can also be used to increase signal through the use of a reflector, normally placed behind the active element and spaced so the reflected signal reaches the element in-phase. Generally the reflector will remain highly reflective even if it is not solid; gaps less than 1⁄10 generally have little effect on the outcome. For this reason, reflectors often take the form of wire meshes or rows of passive elements, which makes them lighter and less subject to wind. The parabolic reflector is perhaps the best known example of a reflector-based antenna, which has an effective area far greater than the active element alone.

Now answer this question: If you wanted to somehow clone the original signal you could use?

Output:
extended conductive surface
